(Embodiment 1)
(1) Overview In the placement support system 1 according to the first embodiment, the cargo placement area is a truck bed, and supports the work of placing cargo on the truck bed.

As shown in FIGS. 1 and 2, the placement support system 1 supports a worker 300 in a loading operation of loading cargo B1 onto a loading platform 110 of a truck 100 at a cargo handling area 201 of a facility 200 such as a warehouse, for example. . The worker 300 is, for example, a driver of the truck 100. The cargo B1 is, for example, a cardboard box containing articles. Identification information is given to each of the plurality of packages B1. For example, a barcode C1 (one-dimensional barcode or two-dimensional barcode) is displayed as identification information on the side of the package B1, that is, the side of the cardboard box. Here, the barcode C1 may be printed on the side of the cardboard box, or a sticker on which the barcode C1 is printed may be affixed to the side of the cardboard box.

Belt conveyors 210 and 211 are installed in the facility 200 to convey cargo B1 in the warehouse to the loading platform 110 of the truck 100. The belt conveyor 210 transports the cargo B1 in the warehouse to the material handling area 201. A part of the belt conveyor 211 extends to the loading platform 110 of the truck 100, and the belt conveyor 211 conveys the cargo B1 conveyed by the belt conveyor 210 to the loading platform 110 of the truck 100. The worker 300 performs the work of loading a plurality of packages B1, which are transported to the loading platform 110 by the belt conveyor 211, onto the loading platform 110.

As shown in FIG. 3, the placement support system 1 of this embodiment includes a cargo information calculation section 14 and a video display section 20.

The cargo information calculation unit 14 calculates cargo information. The cargo information includes at least information on the planned placement position of each of the plurality of packages B1 scheduled to be placed in the placement area A1 (in the present embodiment, the internal space of the box-shaped loading platform 110) within the placement area A1.

Based on the cargo information, the video display unit 20 displays an instruction video P1 that indicates the planned placement position of the work object Bx, which is the work target among the plurality of cargoes B1, at a position associated with the real space. .

As a result, a worker who is working to place the work object Bx in the placement area A1 can perform the work while watching the instruction video P1 displayed at a position associated with the real space, and place the work object Bx in the placement area A1. Since it is difficult to make a mistake in the location of loading, it is possible to improve the efficiency of loading work. Furthermore, since the cargo information calculation unit 14 calculates cargo information including the planned placement positions of the plurality of packages B1, it is possible to reduce the burden on the worker and improve the workability of the cargo work. .

Here, the work object Bx is a work object among the plurality of objects B1, and is a object to be placed next by the worker 300 in the placement area A1.

Furthermore, displaying the instruction image P1 at a position associated with the real space includes directly displaying it at a certain position in the real space, and the image display unit 20 determines the coordinates of the position in the real space where the instruction image P1 is displayed. This includes displaying the instruction image P1 at a position converted into the coordinates of the display area where the instruction image P1 is displayed. That is, the instruction video P1 may be displayed directly at a certain position in the real space by the video display section 20, or may be displayed on the display surface of the video display section 20.

When the video display unit 20 is a projection device that projects a video onto an object in real space, the display area of the video display unit 20 is the real space, and the instruction video P1 is directly displayed in the real space. The video display unit 20 displays the instruction video P1 at a certain position in the real space as a position associated with the real space. Here, the video display section 20 may project the instruction video P1 at a position where the coordinates of the projection position of the instruction video P1 in real space are converted into (associated with) the coordinates of the display area of the video display section 20.

The video display unit 20 may be a transmissive head-mounted display compatible with augmented reality (AR) that displays the instruction video P1 superimposed on the real space visible through the transmissive display. In this case, the display area in which the video display unit 20 displays the instruction image P1 is the display surface of the head-mounted display, and the instruction image P1 is displayed on this display surface. The video display unit 20 displays the instruction image P1 at a position where the coordinates of the virtual display position of the instruction image P1 in real space are converted (associated) with the coordinates of the display surface of the head-mounted display.

Further, the video display unit 20 may be, for example, a non-transparent head-mounted display that displays the instruction video P1 superimposed on an image of the real space created based on a video taken by a camera of the real space, or a tablet terminal, etc. It may also be an information terminal. In this case, the display area in which the video display unit 20 displays the instruction image P1 becomes the display surface of a non-transparent head-mounted display or information terminal display, and the instruction image P1 is displayed on the head-mounted display or the information terminal display. . Then, the video display unit 20 displays the instruction image P1 at a position where the coordinates of the virtual display position of the instruction image P1 in real space are converted (associated) with the coordinates of the display surface of the display of the head-mounted display or the information terminal. indicate.

The identification information detection unit 40 includes a barcode reader 41 (see FIG. 1) that reads the barcode C1 displayed on the luggage B1. The identification information detection section 40 is provided at a position where it can read the barcode C1 displayed on the baggage B1 conveyed by the belt conveyor 211. The identification information detection unit 40 has a communication function to communicate with the processing device 10 via the network 50. The identification information detection unit 40 transmits data including the identification information read from the work object Bx to the processing device 10. In this embodiment, the communication between the identification information detection unit 40 and the processing device 10 is a wired communication method, but a wireless communication method may be used.

The processing device 10 includes an arithmetic processing section 11, a communication section 12, and a storage section 13.

The communication unit 12 communicates using, for example, a wired communication method based on the Ethernet (registered trademark) standard. The communication unit 12 communicates with the video display unit 20 , the arrangement detection unit 30 , and the identification information detection unit 40 via the network 50 . In this embodiment, the communication method of the communication unit 12 is a wired communication method, but a wireless communication method may be used.

The storage unit 13 includes, for example, a nonvolatile memory such as an electrically rewritable EEPROM (Electrically Erasable Programmable Read-Only Memory). The storage unit 13 stores the attribute information of the package B1 scheduled to be loaded onto the truck 100 in association with the identification information of the package B1.

Here, the attribute information includes information regarding the external dimensions (length, width, and height dimensions) and weight of the luggage B1. In this embodiment, the attribute information includes information regarding precautions when handling the package B1 (for example, fragile items, the posture of the package B1 when placed in the placement area A1, the direction of the package B1, etc.). Further, in this embodiment, the attribute information includes information regarding the order in which each of the plurality of packages B1 is taken out from the loading platform 110. For example, when there are two or more delivery destinations for the plurality of packages B1 loaded on the truck 100, the order in which the packages B1 are unloaded is stored in the storage unit 13 as the unloading order for each of the plurality of packages B1.

Note that the storage unit 13 may include an auxiliary storage device such as a hard disk drive. Further, the storage unit 13 may be provided outside the processing device 10 or may be provided in a server device that communicates with the processing device 10 via the network 50.

The arithmetic processing unit 11 is composed of, for example, a microcomputer having a processor and a memory. That is, the arithmetic processing unit 11 is realized by a computer system having a processor and a memory. The computer system functions as the arithmetic processing unit 11 by the processor executing an appropriate program. The program may be pre-recorded in a memory, or may be provided via a telecommunications line such as the Internet, or recorded on a non-transitory recording medium such as a memory card. The arithmetic processing section 11 of this embodiment includes the functions of a cargo information calculation section 14 , a display control section 15 , a determination section 16 , an acquisition section 17 , and an output section 18 .

The load information calculation unit 14 calculates load information for each of the plurality of loads B1 scheduled to be placed in the placement area A1, that is, to be loaded onto the loading platform 110 of the truck 100. The load information includes at least a planned placement position within the placement area A1 for each of the plurality of loads B1 scheduled to be placed in the placement area A1 (in the present embodiment, the loading platform 110 of the truck 100). Specifically, the load information calculation unit 14 acquires attribute information of the plurality of loads B1 scheduled to be loaded onto the loading platform 110 of the truck 100 from the storage unit 13. The cargo information calculation unit 14 calculates cargo information including the planned placement position of each of the plurality of packages B1 within the placement area A1, based on the attribute information of the plurality of packages B1. In other words, the cargo information calculation unit 14 calculates how to stack the plurality of packages B1 in the placement area A1 (planned placement positions). For example, the load information calculation unit 14 calculates the planned placement position so that the heavier baggage B1 among the plurality of pieces of baggage B1 is placed on the lower side. In this way, the cargo information calculation unit 14 calculates the cargo information based on the attribute information of the plurality of packages B1 scheduled to be placed in the placement area A1, and calculates the cargo information according to the number and type of the packages B1 scheduled to be placed. The optimal planned location can be determined. Further, the attribute information includes information regarding the order of take-out, and the load information calculation unit 14 can calculate load information including the planned placement positions of the plurality of packages B1 based on the order of take-out of the plurality of packages B1. can. For example, the load information calculation unit 14 calculates the planned placement position so that the baggage B1 that is taken out later among the plurality of parcels B1 is placed at a position far from the entrance/exit 113 in the placement area A1. The load information calculation unit 14 calculates the planned placement position so that the baggage B1 that is taken out first among the plurality of parcels B1 is placed near the entrance/exit 113 in the placement area A1. Therefore, the cargo information calculation unit 14 can calculate the planned placement position so that the work of taking out the plurality of packages (B1) can be easily performed.

The acquisition unit 17 acquires the identification information of the workpiece Bx transmitted from the identification information detection unit 40. The acquisition unit 17 outputs the acquired identification information to the display control unit 15.

The display control unit 15 associates the instruction video P1 indicating the planned placement position of the work object Bx, which is the work target among the plurality of goods B1, with the real space using the video display unit 20, based on the cargo information. Display in position. Specifically, the display control section 15 determines the arrangement of the work object Bx based on the cargo information calculated by the cargo information calculation section 14 and the identification information of the work object Bx acquired by the acquisition section 17. Image data of an instruction video P1 indicating the planned position is created. The display control unit 15 transmits the image data of the created instruction video P1 to the video display unit 20. When the video display section 20 receives the image data, it displays the instruction video P1 on the projection surface by projecting an image created based on the image data onto the projection surface.

The determination unit 16 determines whether or not the placement of the work object Bx placed in the placement area A1 is appropriate based on the detection result of the placement detection unit 30. The determination unit 16 determines the placement state of the baggage B1 in the placement area A1 based on the image data of the distance image transmitted from the placement detection unit 30 to the processing device 10. Based on the cargo information calculated by the cargo information calculation section 14, the determination section 16 determines the planned placement position of the cargo B1 calculated by the cargo information calculation section 14 and the actual placement position of the work object Bx. Determine whether there is any error.

For example, if the error between the scheduled placement position of the cargo B1 calculated by the load information calculation unit 14 and the placement position of the work object Bx is less than a threshold value, the determination unit 16 determines that the placement position of the work object Bx is appropriate. It is determined that If the error between the planned placement position of the cargo B1 calculated by the load information calculation unit 14 and the actual placement position of the work object Bx is larger than the threshold, the determination unit 16 determines that the placement position of the work object Bx is incorrect. Determine that it is appropriate. In this way, the determining unit 16 determines whether or not the arrangement of the work object Bx placed in the arrangement area A1 is appropriate based on the detection result of the arrangement detecting unit 30, and uses the determination result of the determining unit 16 as the work object Bx. It can be used to correct the placement of object Bx or placed baggage B1.

The output section 18 outputs the arrangement state of the plurality of packages B1 detected by the arrangement detection section 30. The output unit 18 outputs electronic data indicating the arrangement state of the plurality of packages B1 to, for example, a mobile terminal owned by the worker 300. In this way, the output unit 18 outputs the detection results of the placement detection unit 30, and the detection results of the placement detection unit 30 can be used when moving the baggage B1 from the placement area A1. Here, the output mode is not limited to outputting electronic data indicating the arrangement state of the plurality of packages B1, but may print out a list indicating the arrangement state of the plurality of packages B1.

(motion)
The operation of the placement support system 1 according to the first embodiment will be explained with reference to FIG. 4 and the like.

First, the attribute information and identification information of a plurality of packages B1 that are scheduled to be placed on the loading platform 110 of the truck 100, which is the placement area, or loaded on the loading platform 110, are input into the processing device 10 (S1). A user (such as the worker 300) may directly input the attribute information and identification information of the package B1 into the processing device 10, or the processing device 10 may input the attribute information and identification information of the package B1 from another computer connected to the network 50. Information may also be obtained.

When the load information calculation unit 14 of the processing device 10 acquires the attribute information and identification information of the plurality of packages B1 scheduled to be loaded on the cargo platform 110, the cargo information calculation unit 14 calculates the load information including the planned placement position of each of the plurality of packages B1 on the platform 110. Product information is calculated (S2).

Thereafter, when the baggage B1 (work object Bx) is carried by the belt conveyors 210, 211 to the loading platform 110 of the truck 100, the identification information detection unit 40 detects the identification information displayed on the work object Bx (S3 :Yes). The identification information detection unit 40 transmits the identification information detection result to the processing device 10.

When the acquisition section 17 of the processing device 10 receives the identification information transmitted from the identification information detection section 40, the display control section 15 selects the parcel B1 corresponding to the identification information acquired by the acquisition section 17 from among the plurality of parcels B1. Let the object be Bx. Then, the display control unit 15 determines the planned placement position of the work object Bx based on the cargo information, and generates image data for displaying an instruction video instructing the planned placement position at a position associated with the real space. It is transmitted from the communication section 12 to the video display section 20. As a result, the video display unit 20 displays the instruction video P1, which instructs the planned placement position of the work object Bx corresponding to the identification information acquired by the acquisition unit 17 among the plurality of packages B1, at a position associated with the real space. do.

When the video display section 20 receives the image data from the processing device 10, it displays the instruction video P1 on the projection surface by projecting an image created based on the image data onto the projection surface (S4). In the examples shown in FIGS. 1 and 2, the instruction image P1 is a rectangular mark indicating the place where the work object Bx is to be placed (for example, the top surface of the placed baggage B1), and the image display unit 20 displays the instruction image P1 as the place where the work object Bx has been placed. Projected onto the top surface of baggage B1. In this way, when the top surface of the placed baggage B1 placed in the placement area A1 among the plurality of parcels B1 is the planned placement position of the work object Bx, the video display unit 20 instructs the placed baggage B1. Project the image P1. In the example of FIGS. 1 and 2, the instruction image P1 is displayed on the top surface of the baggage B1 on which the work object Bx is placed. Therefore, the worker 300 can easily understand where to place the work object Bx based on the instruction image P1, and can improve the workability of the loading work of placing the baggage B1. Further, the video display unit 20 determines a projection plane on which the instruction image P1 is projected based on the detection result of the arrangement detection unit 30, and projects the instruction image P1 onto this projection plane. Therefore, the image display unit 20 can determine the projection surface on which the instruction image P1 is projected, taking into consideration the placed baggage B1 placed in the placement area A1.

The arrangement detection unit 30 intermittently photographs a distance image of the arrangement area A1 and transmits image data of the distance image to the processing device 10. The determining unit 16 determines the difference between the image data received from the arrangement detecting unit 30 and the image data previously received from the arrangement detecting unit 30, and compares the difference with a reference value (S5).

If the difference is less than or equal to the reference value (S5: No), the determination unit 16 waits to receive image data from the placement detection unit 30, and upon receiving the image data from the placement detection unit 30, repeats the process of step S5. .

On the other hand, if the difference exceeds the reference value (S5: Yes), the determination unit 16 determines that a new baggage B1 has been placed in the placement area A1, and determines whether there is any baggage B1 left to be placed in the placement area A1. A determination is made (S6).

If there is no baggage B1 left to be placed in the placement area A1 in the determination process of step S6 (S6: No), the processing device 10 ends the process of supporting placement of the baggage B1.

In the judgment process of step S6, if the baggage B1 to be placed in the placement area A1 remains (S6: Yes), the judgment unit 16 determines the placement state of the baggage B1 in the placement area A1 based on the detection result of the placement detection unit 30. seek. Then, the determination unit 16 determines whether or not the placement of the work object Bx placed in the placement area A1 is appropriate based on the placement state of the baggage B1 in the placement area A1. That is, the determining unit 16 determines the error between the arrangement state of the baggage B1 determined from the detection result of the placement detecting unit 30 and the cargo information calculated by the cargo information calculating unit 14 (that is, the layout of the plurality of packages B1). demand.

If the error between the arrangement state of the cargo B1 and the cargo information is less than the threshold value (S7: No), the determination unit 16 determines that the arrangement of the work object Bx is appropriate, and proceeds to step S3 to proceed to the next step. performs processing to support the placement of baggage B1.

On the other hand, if the error between the arrangement state of the cargo B1 and the cargo information exceeds the threshold (S7: Yes), the determination unit 16 determines that the arrangement of the work object Bx is inappropriate, and moves to step S2. Then, the cargo information calculation unit 14 calculates the cargo information again. In other words, when the worker 300 places the work object Bx at a position different from the scheduled placement position, the load information calculation unit 14 calculates the load Bx to be placed based on the current placement state of the load B1 in the placement area A1. Calculate the planned placement position again. Therefore, even if the work object Bx is placed incorrectly or the worker 300 intentionally places the work object Bx in a position different from the planned placement position, based on the current placement state of the baggage B1, The placement position of the remaining baggage B1 can be determined.

Note that when the determination unit 16 determines that the arrangement of the work object Bx is inappropriate, the display control unit 15 displays an image indicating that the arrangement of the work object Bx in the arrangement area A1 is inappropriate. It may be displayed on the section 20. For example, the display control unit 15 projects an image (a mark, a character, etc.) indicating that the placement is incorrect onto the workpiece Bx placed at an inappropriate position. Thereby, the placement support system 1 can make the worker 300 aware that the placement of the work object Bx is inappropriate. Note that when the determination unit 16 determines that the placement of the work object Bx is inappropriate, the placement support system 1 may output a warning by voice etc. This can make you realize that the placement of the information is inappropriate.

Further, when the determination unit 16 determines that the placement of the work object Bx is inappropriate, the display control unit 15 causes the video display unit 20 to display an instruction video indicating an appropriate scheduled placement position of the work object Bx. It's okay. Thereby, the placement support system 1 can present the correct scheduled placement position of the work object Bx to the worker 300 again.

In this way, when the determination unit 16 determines that the arrangement of the work object Bx is inappropriate, the video display unit 20 performs the first process. The first process is a process in which the video display unit 20 displays at least one of an image indicating that the placement of the work object Bx in the placement area A1 is inappropriate and an instruction image indicating an appropriate planned placement position. be. By the video display unit 15 performing the first process, it is possible to present to the worker 300 that the placement of the work object Bx is inappropriate, or the appropriate planned placement position of the work object Bx. .

Further, when it is determined in step S6 that there is no remaining baggage B1, the determination unit 16 determines the placement state of the baggage B1 in the placement area A1 based on the detection result of the placement detection unit 30, and It may be determined whether or not the placement of the placed work object Bx is appropriate. For example, the determination unit 16 compares the placement state of the package B1 obtained from the detection result of the placement detection unit 30 with the cargo information calculated by the cargo information calculation unit 14 (that is, the planned placement positions of the plurality of packages B1). Find the error. If the error between the placement state of the baggage B1 and the planned placement position is less than the threshold value, the determination unit 16 determines that the placement of the work object Bx is appropriate and ends the process. On the other hand, if the error between the placement state of the baggage B1 and the planned placement position exceeds the threshold, the determination unit 16 determines that the placement of the work object Bx is inappropriate.
