<< 1-3. Image recording during cleaning operation >>
Hereinafter, an example of an object search processing procedure performed by the object search system 100 according to the present invention will be described with reference to flowcharts.
4 and 5 are flowcharts of processing relating to object search executed by the object search system 100 of the present invention. FIG. 4 shows a process of storing a recorded image during the cleaning operation of the self-propelled cleaner as the self-propelled electronic device prior to the object search. FIG. 5 shows processing executed on the communication terminal device side and the self-propelled cleaner side as the operation device when performing object search.

  First, it demonstrates based on FIG. The self-propelled cleaner 1 as a self-propelled electronic device performs autonomous traveling for the cleaning operation which is the original function, but photographs various places in the traveling room with the camera 41C, and records the recorded images. Stored in the device storage unit 61. The device control unit 11 secures a FIFO area for storing the recorded image in the device storage unit 61, and sequentially stores the recorded image in the FIFO area. When the FIFO capacity is full, the device control unit 11 sequentially erases the previously recorded images from the recorded images stored in the FIFO area, and stores a new recorded image in the vacant area.

In the standby state, the device control unit 11 monitors whether a start switch (not shown) included in the device operation unit 51 is turned on to instruct the start of the cleaning operation (step S11 in FIG. 4). If the instruction | indication of cleaning operation start is made (Yes of step S11), the apparatus control part 11 will control the power part 21 so that it may drive | work, avoiding the obstacle detected by the obstacle detection part 14. FIG. Further, the electric blower 33 and the brush motor 34 are rotated to perform a cleaning operation (step S13).
During traveling, every time a predetermined period elapses (step S15), the camera 41C takes an image and acquires a recorded image (step S17).
Subsequently, the object recognition unit 41A performs object recognition of the recorded image that has been shot, and adds the position information acquired by the position recording unit 71 to the recorded image. The position recording unit 71 sequentially updates information to a position that changes with traveling. The memory area of the position information 63 may be secured in the device storage unit 61, and the position information updated by the position recording unit 71 may be sequentially stored and updated in the position information 63. Further, the device control unit 11 adds a tag to the recorded image as the tag addition unit 11a (step S19).
The function of the tag addition unit 11a is to add a keyword related to the object recognized by the object recognition unit 41A to the recorded image. For example, when a key that has fallen on the floor in front of the travel path is shown in an image captured by the camera 41C, the object recognition unit 41A uses a well-known pattern recognition technique to classify an object (object) of the class “key”. Recognize that is reflected. The class here is a general concept of an object such as “key”, “clip”, and “pen”. As described above, a technique for extracting an object included in an image at a class level by applying pattern matching is known as general object recognition. As illustrated in FIG. 1, the device storage unit 61 may store in advance as a tag database 65 a feature amount and a tag of an object to be recognized.

In pattern matching, generally, features of an object to be recognized are extracted as feature amounts by a predetermined feature amount extraction process and stored in a memory. As the feature amount extraction processing, for example, SIFT (Scale-Invariant Feature Transform) that obtains a local feature amount that is invariant to scale change or rotation of an image based on the arrangement of shading as a local feature amount of an object
Various methods are known. When a recorded image is given, the same feature amount extraction process is applied to the recorded image to extract the feature amount, and if there is something similar to the feature amount stored in advance in the memory, it corresponds. It is determined that the object (object) is reflected in the image.

  For general object recognition, a technique for recognizing only an object instance, for example, a key having a specific shape among various objects included in a class of “key” is known as a specific object recognition technique.

As described above, the device control unit 11 adds position information and a tag at the time of shooting to the recorded image and stores them in the device storage unit 61. In addition, the self-propelled cleaner 1 may be provided with a real time clock (not shown in FIG. 1), and the date and time at which the photographing is pointed may be further added to the recorded image.
Subsequently, the device control unit 11 determines whether to end or continue the cleaning operation (step S21). When continuing (No of step S21), a routine returns to above-mentioned step S13, and continues a cleaning operation | movement and intermittent imaging | photography.
When the cleaning operation is finished (Yes in step S21), the device control unit 11 returns the self-propelled cleaner 1 to the charging stand arranged in the room (step S23). When returning to the charging stand, the cleaning operation process is terminated (step S25). Various conditions are conceivable as conditions for ending the cleaning operation. In particular, when the remaining capacity of the rechargeable battery 12 is less than a predetermined value, it is determined that it is necessary to return to the charging stand. Alternatively, or in addition thereto, it may be determined that the cleaning operation is terminated when a predetermined period has elapsed since the start of the cleaning operation. Furthermore, when the spot mode for cleaning the periphery of the position designated as the operation mode is selected, the cleaning operation may be determined to be finished when a predetermined range is cleaned around the designated position.

<< 1-4. Object search process >>
Next, processing at the time of object search will be described. FIG. 5 shows two flowcharts together. The flowchart on the left side is a process executed by the terminal control unit 111 on the communication terminal apparatus 110 side, and the flowchart on the right side is a process executed by the device control unit 11 on the self-propelled cleaner 1 side. The communication terminal device 110 and the self-propelled cleaner 1 perform processing in cooperation while performing communication via the communication network 90.

  First, it is assumed that the user of the communication terminal device 110 performs an operation on the terminal operation unit 114 to select a menu for executing object search. Then, the terminal control unit 111 that monitors the operation input of the terminal operation unit 114 (step S31), responds to the operation (Yes in step S31), and displays a screen that accepts an input of a keyword as a query. (Step S33). At this stage, the terminal operation unit 114 functions as the query input unit 114a. Note that display data of a menu screen for executing an object search and a screen for accepting an input of a query are stored in advance in the terminal storage unit 115. It is assumed that the user performs an operation for inputting a query on the screen to the terminal operation unit 114. Then, the terminal control unit 111 that monitors the operation input (Step S35) responds to the operation (Yes in Step S35) and sends the input query from the terminal communication unit 112 via the communication network 90. Send to the traveling vacuum cleaner 1. Then, a request is made to search for an image to which a tag related to the query is added (step S37).

Let's move on to the description of the self-propelled cleaner 1 side. In the self-propelled cleaner 1, the device control unit 11 that monitors whether the device communication unit 81 has received a request for object search (step S51), responds to the request (Yes in step S51). A recorded image to which a tag related to the query is added is extracted from the device storage unit 61 (step S53). This process of the device control unit 11 corresponds to the function as the search unit 11b.
Returning to the description of the communication terminal device 110 side. When one or more recorded images are extracted as the search results, the device control unit 11 transmits the images from the device communication unit 81 to the communication terminal device 110 via the communication network 90 (step S53). If there is no corresponding image, a search result to that effect is transmitted to communication terminal apparatus 110.

The terminal control unit 111 of the communication terminal device 110 monitors whether or not the terminal communication unit 112 has received a search result from the self-propelled cleaner 1 (step S39). In response to receiving the search result (Yes in step S39), the search result is displayed on the terminal display unit 113 (step S41). At this stage, the terminal display unit 113 functions as the search result output unit 113a.
When the image corresponding to the search result is found, the terminal control unit 111 displays the list on the terminal display unit 113 together with the position information added to the image. If there is no corresponding image, a message to that effect is displayed on the terminal display unit 113. When the date and time when the image was taken is added to the search result image, the date and time may be displayed together with the image.

  The above is the processing of the device control unit 11 and the terminal control unit 111, but the user finds an image that matches the one that the user is looking at by looking at the image displayed on the terminal display unit 113, and the position information displayed together with the image Based on this, you can identify where you are looking for.

Then, it is monitored whether any displayed image is selected by the user (step S43). If any image is selected (Yes in step S43), the position information added to the selected image is transmitted to the self-propelled cleaner 1 (step S45).

  The device control unit 11 of the self-propelled cleaner 1 performs the same processing as steps S51 to S53 in FIG. 5 and then monitors whether or not the device communication unit 81 has received the position information from the communication terminal device 110. (Step S55). When the position information is received (Yes in step S55), the device control unit 11 starts the traveling of the self-propelled cleaner 1 in response to the position indicated by the position information. When the movement to the target location is completed while avoiding the obstacle (Yes in step S59), the device control unit transmits the arrival at the target location to the communication terminal device 110 (step S61).

Returning to the description of the processing of the terminal control unit 111. The terminal control unit 111 waits for the terminal communication unit 112 to receive a notification that the self-propelled cleaner 1 has arrived at the target location (step S47). When the notification is received (Yes in step S47), the terminal control unit 111 causes the terminal display unit 113 to display a message indicating that the self-propelled cleaner 1 has arrived at the target location (step S49), and ends the process. .
The device control unit 11 performs control so that when the self-propelled cleaner 1 arrives at the target location, the surrounding state is captured by the camera 41C and transmitted to the communication terminal device 110. The terminal control unit 111 When the communication unit 112 receives the image, the terminal display unit 113 may be controlled to display the received image.
