Detailed ways

The concept, specific structure and technical effects of the present utility model will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, characteristics and effects of the present utility model.

Example 1

This embodiment provides an image acquisition device, which is applied to the box 13, or an ideal lighting environment, such as an open indoor and outdoor space, or a dark room that can be closed, for detecting the object to be tested 4, especially the electronic product. Appearance, as shown in Figure 1, the image acquisition device is mainly composed of a receiving platform 2 for placing the detection area of the object to be tested 4, a mirror 3 arranged above the receiving platform 2 and located on one side of the detection area, and a A first camera 1 and the like are formed on the top of the platform 2 and the reflector 3 and used to collect images of the detection area and the area where the reflector 3 is located.

It can be seen from the above structure that when the object to be tested 4, such as a mobile phone, tablet computer and other electronic products are placed on the receiving platform 2, the side image of the object to be tested 4 is displayed in real time through the reflector 3. Therefore, with the cooperation of the reflector 3, the The image acquisition device can use a single camera to capture the front image and side image of the object to be tested 4 without setting multiple cameras to capture the image of the object to be tested 4 , thus simplifying the structure and reducing equipment costs. In addition, the front and side information of the object to be tested 4 can be obtained through a single image, which is beneficial to simplify the process of image processing, that is, to simplify the operation, improve the efficiency of detection, and facilitate the subsequent identification of various appearance features of the object to be tested 4, such as Defects, scratches, etc.

Specifically, as shown in FIG. 1 , there are preferably multiple mirrors 3 in this embodiment, and they are arranged around the circumferential layout of the detection area. Therefore, when the object to be measured 4 is placed in the detection area, the setting structure realizes the measurement of different angles of the side of the object to be measured 4, such as the four directions of east, west, northwest, to avoid omission of one side, and no need for secondary shooting, which is convenient for subsequent testing. Obviously, the number of the mirrors 3 in this embodiment can be set to one, two or three other numbers according to actual needs, for example, only one side image or two side images of the object to be tested 4 needs to be detected. Or the side image of the object to be tested 4 is displayed through a ring-shaped mirror 3 . Therefore, the specific number of the reflecting mirrors 3 is not described in detail in this embodiment.

As shown in FIG. 1 , preferably, the shooting direction of the first camera 1 is generally perpendicular to the detection area, such as vertical or with a slight inclination angle perpendicular to the detection area, so that the front and side images captured by the first camera 1 are It is ideal to avoid the phenomenon of deformity, which is not conducive to subsequent image feature recognition.

As a better preferred manner, as shown in FIG. 2 , the mirrors 3 in this embodiment can be connected end to end in sequence, and the enclosed area is the detection area. Through this arrangement, the mirror 3 is made to surround the side of the object 4 to be tested as much as possible, that is, its circumference is surrounded in all directions, so as to avoid a partial area of the side of the object to be tested 4 and the chamfered area not displayed on the mirror 3, so as to avoid the situation of missed detection. Of course, when there are a plurality of reflecting mirrors 3 in this embodiment, they can also be arranged around at intervals, and it is only necessary to keep the length of the reflecting mirrors 3 greater than the length or width of the object to be measured 4.

As shown in FIG. 1 , the number of the reflecting mirrors 3 in this embodiment is preferably four, and they are arranged opposite to each other. The images of the object to be tested 4 are acquired from the four directions of front, rear, left, right, and right of the object to be tested. The reflecting mirror 3 may preferably be a flat mirror, so as to better reflect the side portion of the object to be tested 4 and prevent the phenomenon of image deformation in the mirror from occurring.

In addition, the reflector 3 in this embodiment can also be designed as a curved mirror according to actual needs, so as to match the object to be measured 4 whose side is a curved surface, so that the length of the object to be measured 4 in the image obtained by the camera is closer to the object to be measured. the length of the object 4 itself.

As shown in FIG. 2 , the receiving platform 2 may be constituted by a base plate 22 for mounting the reflector 3 and the like. Among them, the bottom plate 22 is formed with a part of the protrusions forming the protrusions 221 and the like that match the shape of the detection area. It can be seen that the detection area where the object to be tested 4 is placed can be slightly higher than the bottom of the reflector 3 through the raised portion 221 , which ensures that the side surface of the object to be tested 4 can be displayed in the reflector 3 as low as possible.

As a preferred way, in order to reduce the manufacturing cost, a part of the raised part 221 is hollowed out to form a hollow part 222 matching the shape of the detection area; 4 of the receiving plate 21. Through the detachable connection between the receiving plate 21 and the hollow portion 222, the manufacturing process of the bottom plate 22 is reduced, and the disassembly and replacement are convenient.

Preferably, the receiving plate 21 in this embodiment is a transparent panel, so that the detection area becomes a transparent area, which facilitates the subsequent photographing of the image of the object to be tested 4 through the camera from the back of the receiving plate 21 . In addition, through the connection structure between the raised portion 221 and the receiving plate 21, the receiving platform 2 does not need the entire detection area to be a transparent area, only the area where the receiving plate 21 is located is a transparent area, which reduces production and manufacturing costs.

In addition, in order to facilitate the fixing of the receiving platform 2 in the box body 13 or on the corresponding bracket, the receiving platform 2 further comprises: a mounting base plate 24 fixedly connected with the bottom plate 22. Moreover, the mounting substrate 24 may preferably be provided with a hollow area (not shown in the figure) to match the hollow portion 222 of the bottom plate 22 , so as to facilitate the subsequent photographing of the image of the object to be tested 4 through the camera from the back of the receiving plate 21 .

As shown in FIG. 3 , the edge of the hollow portion 222 is partially concave to form an inner edge surface 2211 , so that the receiving plate 21 can be placed through the inner edge surface 2211 to realize the engagement between the convex portion 221 and the receiving plate 21 . Obviously, the receiving plate 21 and the protruding portion 221 in this embodiment can also be integrally formed, which will not be repeated here.

In detail, the shape of the detection area in this embodiment is preferably any one of a square, a rectangle, and a circle. By adapting the shape of the detection area to the outline of the object to be tested 4, it prevents the partial area of the side of the object to be tested 4 from being parallel to the mirror 3, which causes the image formed in the mirror 3 to be deformed, which is beneficial for subsequent Feature recognition. As shown in FIG. 2 , the present embodiment only takes a rectangular shape as an example for brief description, so as to match the shapes of most electronic products such as mobile phones and tablets. Since the detection area is a rectangle, when the rectangular object to be tested 4 is placed in the rectangle, the distance between each reflector 3 and the object to be tested 4 is approximately the same, which can better ensure that the image formed by each reflector 3 is located in the first Within the depth of field of a camera 1, in order to avoid that the images displayed by the mirrors 3 in the images collected by the first camera 1 cannot be kept clear at the same time. In addition, the reflecting mirrors 3 in this embodiment are two long-side reflecting mirrors 3 and two short-side reflecting mirrors 3, which are only described as an example. Of course, the reflector 3 can also be designed to be of the same length according to actual requirements, which will not be repeated here.

In this embodiment, the reflector 3 can be located above the receiving platform 2, or its bottom can be connected to the receiving platform 2, and this embodiment only takes the connecting of the reflector 3 and the receiving platform 2 as an example for illustration, in order to facilitate the The light is gathered to avoid light leakage, resulting in bright spots and other background interferences in the image formed in the mirror 3, which facilitates the separation of the object to be tested 4 from the background image in the subsequent image processing process.

In addition, as shown in FIG. 2 and FIG. 4 , the reflector 3 in this embodiment can be composed of a reflector body 31 , a fixed plate 32 for fixing the reflector body 31 , a rotating plate 33 connected to the fixed plate, and a rotating plate 32 . Actively connected mirror brackets, etc. Therefore, the rotation angle of the mirror body 31 can be easily adjusted by this structure.

In addition, the rotating plate 33 is provided with a rotating hole 331 . In actual use, the rotating plate 33 can be driven by inserting a corresponding rotating shaft into the rotating hole 331 , thereby realizing the angle adjustment of the mirror 3 .

In addition, as shown in FIG. 4 , there are at least two rotating holes 331 opened on the rotating plate 33 , one of which is a shaft hole and the other is a rotating shaft hole. Wherein, when the mirror 3 rotates, it rotates around the central axis inserted into the shaft hole, and the adjustment of the mirror 3 is driven by the rotating shaft inserted into the shaft hole, thereby realizing the circular rotation of the mirror 3, which facilitates the adjustment of the mirror 3. Precise control of reflection angle. Wherein, there are preferably two rotating shaft holes in this embodiment, and they are located on the same circumference.

Moreover, as shown in FIG. 4 , the shape of the mirror body 31 is a transparent multi-faceted prism, and one face of the multi-faceted prism is coated with a mirror coating 311 , and the mirror coating 311 is attached to the fixing plate 32 . Therefore, the image of the object to be tested can be better reflected into the camera through the mirror coating.

Further preferably, the included angle between the mirror coating 311 of each reflecting mirror 3 and the receiving platform 2 is 15 degrees to 30 degrees. By setting the angle of the included angle, the image presented in the reflector 3 can be clearly displayed. Preferably, the included angle is preferably 20 degrees to obtain an ideal imaging effect.

As shown in FIG. 4 , the shape of the mirror body 31 is preferably a transparent triangular prism, so that the rotation trajectory of the edge of the mirror body 31 is circular through the triangular prism, and the cross section of the triangular prism is reduced in the trajectory. The occupied area of the reflective mirror surface 32 is maximized, which is beneficial to the image acquisition of the first camera 1 . In addition, it should be noted that the shape of the mirror body 31 can also be designed as other polyhedral prisms, such as quadrangular prisms, pentagonal prisms, etc., according to the actual situation, which will not be described here.

In addition, the number of rotating plates 33 in this embodiment is preferably two, and the opposite ends of the mirror body 31 are closed to prevent light from entering from the opposite ends of the mirror body 31, thereby avoiding the image in the mirror coating 311. interfered with by other light.

Further preferably, the cross-sectional shape of the triangular prism is an isosceles right triangle. In order to make the two outer and two facets of the mirror body 31 just perpendicular to each other, it is convenient for the camera to obtain the image reflected in the mirror coating from top to bottom.

In addition, it is worth mentioning that, in this embodiment, the side wall of the rotating plate 33 adhering to the mirror body 31 is coated with a light-blocking coating, such as a black coating, to prevent light from passing from the opposite two sides of the mirror body 31 . end incident, so as to prevent the image in the mirror coating 311 from being disturbed by other light rays.

In addition, as shown in FIG. 2 , the mirror bracket can be composed of a connecting piece 5 for movably connecting two adjacent mirror bodies 31 , a locking piece for lockingly connecting the mirror body 31 and the connecting piece 5 , etc. constitute. The mirror body 31 is locked by the locking member after being rotated on the connecting member 5 to a predetermined angle.

It can be seen from this that the adjustment and fixation of the rotation angle of the mirror body 31 is achieved through the cooperation of the locking member and the connecting member 5 . In addition, not only the angle adjustment of a single reflecting mirror 3 can be realized through the connecting member 5, but also adjacent reflecting mirrors 3 can be connected together to form an end-to-end connection. The number of the connecting pieces 5 in this embodiment is the same as the number of the reflecting mirrors 3 . In addition, the fixed connection between the reflector 3 and the receiving platform 2 can also be realized through the connecting member 5 , and the rotation adjustment of the reflector 3 is not affected.

Specifically, as shown in FIG. 2 , the connector 5 in this embodiment is mainly composed of a first body 51 with a first chute 511 and a second body 51 connected with the first body 51 and with a second chute 521 . The body 52 is composed of a rotating shaft connected with one of the reflecting mirrors and inserted into the first sliding groove 511 , a rotating shaft connected with the other reflecting mirror and inserted into the second sliding groove 521 , and the like. The first body 51 is rotatably connected to the rotating shaft inserted into the rotating hole 331 of one of the mirrors 3 through the first sliding slot 511 , and the second body 52 is inserted into the rotating hole of the other reflecting mirror 3 through the second sliding slot 521 . The rotating shaft in 331 is connected in rotation; the locking member includes: a locking nut for locking the connecting shaft. Wherein, the first body 51 and the second body 52 are preferably perpendicular to each other, so that the shape enclosed by the mirrors 3 after being connected is a rectangle.

It can be seen from this that the rotation of the mirror 3 angles is achieved by the sliding of the rotating shaft between the corresponding chutes, and then after rotating to the set angle, the locking of the rotating shaft can be realized by the locking nut. Obviously, in this embodiment, other components can also be used to replace the lock nut to realize the locking of the rotating shaft, and the comparison in this embodiment does not make a specific limitation. In addition, it should be noted that the first chute 511 and the second chute 521 in this embodiment can also be provided on the mirror body 31 , and the angle adjustment of the mirror 3 can be realized through the rotating shaft disposed on the connecting member 5 . and fixed, so I won't go into too much detail here.

Preferably, the first chute 511 and the second chute 521 in this embodiment are arc-shaped slots. The rotation of the mirror 3 is a smooth circular rotation through the arc-shaped groove.

In addition, as shown in FIG. 2 , the connector 5 includes: a third body 53 which is connected with the first body 51 and the second body 52 and is detachably connected with the receiving platform 2 . Through the detachable connection between the third body 53 and the bottom plate 22 of the receiving platform 2 , the connection between the mirror 3 and the receiving platform 2 is realized without affecting the rotation thereof.

Embodiment 2

This embodiment also provides an image acquisition device, which is a further improvement on the above-mentioned embodiment. The improvement lies in that, as shown in FIG. 5 , the image acquisition device in this embodiment further includes: The N groups of first light source lamps 6 above the platform 2 are used to fill light on the object 4 to be measured, wherein N is a positive integer.

The first light source lamp 6 illuminates the object to be tested 4 with supplementary light, so that the image obtained by the camera is clearer, which is convenient for subsequent image processing, such as separation of the object to be tested 4 from the background, threshold processing, image segmentation, and feature extraction.

Specifically, there are multiple first light source lamps 6 in each group, located above the reflector 3 , and arranged around a plane perpendicular to the shooting direction of the first camera 1 . Therefore, the first light source lamp 6 can illuminate all parts of the object to be tested 4 from above, especially the side parts, so as to avoid the phenomenon that the front image of the object to be tested 4, the side image and the background brightness are not easily distinguished in the collected images. .

In detail, as shown in FIG. 6 , the shape of the area surrounded by the first light source lamp 6 can be designed as any one of square, rectangle and circle according to actual requirements, and this embodiment only takes a rectangle as an example for description. Further preferably, the first light source lamps 6 in this embodiment are preferably two groups, and the adjacent two groups of the first light source lamps 6 are arranged at intervals from bottom to top along the direction of the first camera 1 perpendicular to the shooting detection area, so as to pass through. The cooperation of the two groups of first light source lamps 6 keeps the light irradiated on the surface of the object to be tested 4 uniform. The light plays the role of supplementing the strong light or supplementing the weak light, so as to avoid the phenomenon such as bright spots appearing in the part of the object to be tested 4 .

In detail, the first light source lamps 6 are preferably rectangular surface light sources, and the number of the first light source lamps 6 is four, and they are arranged opposite to each other. Among them, two of the first light source lamps 6 are long-side rectangular surface light sources, and the other two are short-side surface light sources.

In addition, as shown in FIG. 6 , the image acquisition device in this embodiment further includes: a first bracket 7 for fixing the first light source lamp 6 , and the first bracket 7 has a detection area and a reflection area for the first camera 1 to shoot. The hollow area 71 of the mirror 3; the coupling member 8 for movably connecting the first light source lamp 6 and the first bracket 7; the locking member for locking the first light source lamp 6 and the coupling member 8; After the light source lamp 6 is rotated on the coupling member 8 to a preset angle, it is locked by the locking member.

It can be seen from this that the first bracket 7 is provided with a hollow area 71 for shooting by the camera 1, and a plurality of connecting pieces 8 arranged along the circumference of the hollow area 71, and since the connecting piece 8 and the first light source lamp 6 are movable It is connected, so the structure is simple, which not only facilitates the installation and disassembly of the first light source lamp 6, but also can easily adjust the irradiation angle of the first light source lamp 6 through the cooperation of the coupling member 8 and the locking member, so that the first light source lamp 6 can be easily adjusted. After the light source lamp 6 is rotated to an appropriate irradiation angle, it is ensured that the light irradiated by the object to be measured 4, such as a mobile phone, is relatively uniform, thereby ensuring that the camera 1 can capture a clear image.

In detail, as shown in FIG. 6 , the coupling member 8 in this embodiment is mainly composed of a vertical portion 81 with a circular arc groove 83 , a horizontal portion 82 connected to the vertical portion 81 and adjacent to the first bracket 7 , and The side walls of the first light source lamp 6 are connected with a fulcrum (not marked in the figure) and the like. Wherein, the vertical part 81 is rotatably connected with the support shaft through the arc groove 83; the locking member is a locking nut for locking and connecting the support shaft.

It can be seen from this that the adjustment and fixation of the irradiation angle of the first light source lamp 6 is realized by the sliding of the rotating shaft between the corresponding sliding grooves.
