This embodiment provides an image acquisition device, be applied to box 13, or the daylighting environment of ideal, such as open indoor outer space, or in the dark room that can seal, be used for detecting determinand 4, especially the outward appearance of electronic product, as shown in fig. 1, this image acquisition device mainly comprises accepting platform 2 by the detection zone that is used for placing determinand 4, set up and accept platform 2 top and be located the speculum 3 of one side of detection zone, set up and accept platform 2 and speculum 3's top and be used for gathering the first camera 1 of the image in detection zone and speculum 3 place region etc..

By the structure, when the object to be measured 4, such as a mobile phone, a tablet personal computer and other electronic products, is placed on the bearing platform 2, the side image of the object to be measured 4 is displayed in real time through the reflector 3, so that the image acquisition device can shoot the front image and the side image of the object to be measured 4 by adopting a single camera with the help of the cooperation of the reflector 3, the image of the object to be measured 4 does not need to be shot through arranging a plurality of cameras, the structure is simplified, and the equipment cost is reduced. In addition, the front and side information of the object 4 to be detected can be obtained through a single image, which is beneficial to simplifying the image processing flow, namely simplifying the operation, improving the detection efficiency, and facilitating the subsequent identification of various appearance characteristics of the object 4 to be detected, such as defects, scratches and the like.

Specifically, as shown in fig. 1, the reflecting mirrors 3 in the present embodiment are preferably plural and arranged in a circumferential arrangement around the detection area. Consequently, when determinand 4 placed in the detection zone, realize the measurement to the different angles of determinand 4's lateral part through this structure that sets up, if four directions in southeast, west and north, avoid having one side to appear omitting, need not take the secondary, the subsequent detection of being convenient for. Obviously, the number of the reflectors 3 in this embodiment may be set to be one, two, or three or other numbers according to actual requirements, for example, only one side image or two side images of the object 4 need to be detected, or the side image of the object 4 is displayed through one annular reflector 3. Therefore, the specific number of the reflectors 3 will not be described in detail in this embodiment.

As shown in fig. 1, preferably, the shooting direction of the first camera 1 is substantially perpendicular to the detection area, for example, perpendicular to the detection area or slightly perpendicular to the detection area with a certain inclination angle, so that the front image and the side image shot by the first camera 1 are ideal, thereby avoiding the occurrence of the malformation phenomenon and being unfavorable for the subsequent image feature recognition.

Preferably, as shown in fig. 2, the mirrors 3 in this embodiment may be connected end to end, and the enclosed area is a detection area. By the arrangement mode, the reflector 3 surrounds the side part of the object to be detected 4 as much as possible in an all-around mode, namely the circumferential direction of the reflector 3, partial areas of the side part of the object to be detected 4 are avoided, and the chamfer area is not displayed in the reflector 3, so that the condition of missing detection is avoided. Of course, when there are a plurality of reflectors 3 in the present embodiment, they may be disposed at intervals, and it is only necessary to keep the length of the reflector 3 greater than the length or width of the object 4 to be measured.

As shown in fig. 1, the number of the reflecting mirrors 3 in the present embodiment is preferably four, and two are arranged to face each other. To acquire images of the object 4 from four directions of the object 4. The reflecting mirror 3 may preferably be a flat mirror to better reflect the side of the object 4 to be measured and prevent the phenomenon that the image formed in the mirror is distorted.

In addition, the reflector 3 in this embodiment may also be designed as an arc mirror according to actual requirements to match the object 4 to be measured whose side is an arc, so that the length of the object 4 to be measured in the image acquired by the camera is closer to the length of the object 4 to be measured.

As shown in fig. 2, the receiving platform 2 may be constituted by a base plate 22 or the like for mounting the reflecting mirror 3. The bottom plate 22 is partially protruded to form a protrusion 221 matching the shape of the detection area. Therefore, the detection area for placing the object 4 can be slightly higher than the bottom of the reflector 3 through the protrusion 221, and the side surface of the object 4 can be ensured to be displayed in the reflector 3 to the utmost extent.

Preferably, in order to reduce the manufacturing cost, a part of the protrusion 221 is hollowed to form a hollowed-out portion 222 matching the shape of the detection area; the receiving platform 2 further comprises: a bearing plate 21 for covering the hollow part 222 and for placing the object 4 to be tested. Through the detachable connection between the bearing plate 21 and the hollow part 222, the manufacturing process of the bottom plate 22 is reduced, and the bottom plate is convenient to disassemble and replace.

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 shooting of the image of the object 4 by the camera from the back of the receiving plate 21. In addition, through the connection structure between the protruding portion 221 and the receiving plate 21, the receiving platform 2 does not need to have the whole detection area as a transparent area, and only the area where the receiving plate 21 is located is the transparent area, so that the production and manufacturing costs are reduced.

In addition, in order to facilitate the fixing of the receiving platform 2 in the housing 13 or on a corresponding support, the receiving platform 2 further comprises a mounting base plate 24 fixedly connected to the base plate 22. Moreover, the mounting substrate 24 may preferably have a hollow portion (not shown) for matching with the hollow portion 222 of the bottom plate 22, so as to facilitate the subsequent shooting of the image of the object 4 from the back of the receiving plate 21 by a camera.

As shown in fig. 3, the edge of the hollow portion 222 is partially recessed to form an inner edge surface 2211, so that the receiving plate 21 is placed on the inner edge surface 2211, and the protrusion 221 and the receiving plate 21 are engaged with each other. Obviously, the bearing plate 21 and the protrusion 221 in this embodiment may also be integrally formed, and will not be described herein.

In detail, the shape of the detection area in the present embodiment is preferably any one of a square, a rectangle, and a circle. The shape of the detection area is matched with the outline of the object to be detected 4, so that the phenomenon that the image formed in the reflector 3 is deformed due to the fact that the partial area of the side part of the object to be detected 4 is not parallel to the reflector 3 is prevented, and subsequent feature recognition is facilitated. As shown in fig. 2, the present embodiment is only briefly described with a rectangular shape as an example to match the shapes of most electronic products such as mobile phones and tablet computers. Because the detection area is the rectangle, consequently when rectangular determinand 4 is placed in the rectangle, the distance between each speculum 3 and determinand 4 is roughly the same, can be better guarantee that the image that each speculum 3 becomes is located the depth of field of first camera 1 to the image that each speculum 3 shows can't keep clear simultaneously in the image that first camera 1 gathered to avoid appearing. The mirrors 3 in the present embodiment are two long-side mirrors 3 and two short-side mirrors 3, and this is merely an example for explanation. Of course, the reflector 3 may also be designed to have the same length according to actual requirements, and will not be described herein.

In this embodiment, the reflector 3 may be located above the supporting platform 2, or the bottom of the reflector may be connected to the supporting platform 2, and this embodiment only takes the example that the reflector 3 is connected to the supporting platform 2, so as to facilitate light collection, avoid light leakage, and cause bright spots in the image formed in the reflector 3 and other background interferents, and facilitate separation of the object to be measured 4 from the background image in the subsequent image processing process.

As shown in fig. 4, the reflector body 31 is a transparent polygonal prism, and the polygonal prism has a prism surface coated with a mirror coating 311, and the mirror coating 311 is attached to the fixing plate 32. Therefore, the mirror coating can better reflect the image of the object to be measured into the camera.

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

As shown in fig. 4, the shape of the reflector body 31 is preferably a transparent triangular prism, so that the rotation track of the edge of the reflector body 31 is circular through the triangular prism, the occupied area of the cross section of the triangular prism in the track is reduced, the area of the reflector surface 32 is maximized, and the image acquisition of the first camera 1 is facilitated. In addition, it should be noted that the shape of the reflector body 31 may also be designed as other polyhedral prisms, such as a quadrangular prism, a pentagonal prism, etc., according to actual situations, and will not be described herein in detail.

In addition, the two rotating plates 33 are preferably provided in the present embodiment, and close the opposite ends of the mirror body 31 to prevent light from being incident from the opposite ends of the mirror body 31, thereby preventing the image in the mirror coating 311 from being interfered by other light.

Further preferably, the triangular prism has a cross-sectional shape of an isosceles right triangle. So that two outer prism faces of the reflector body 31 are just perpendicular to each other, and the camera can conveniently obtain the image reflected by the mirror coating from top to bottom.

In addition, it should be noted that in the present embodiment, the side wall of the rotating plate 33, which is attached to the reflector body 31, is coated with a light-blocking coating, such as a black coating, to prevent light from entering from the two opposite ends of the reflector body 31, so as to prevent the image in the mirror coating 311 from being interfered by other light.

Wherein, the reflector body 31 is locked by the locking member after rotating to a preset angle on the connecting member 5.

Thus, the adjustment and fixation of the rotation angle of the mirror body 31 are achieved by the cooperation of the locking member and the connecting member 5. In addition, the angle adjustment of a single reflector 3 can be realized through the connecting piece 5, and adjacent reflectors 3 can be connected together to form 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. Moreover, the fixed connection between the reflector 3 and the bearing platform 2 can be realized through the connecting piece 5, and the rotation adjustment of the reflector 3 is not influenced.

Obviously, other components may be used in the present embodiment instead of the lock nut to lock the rotating shaft, and the present embodiment is not limited in particular. In addition, it should be noted that the first sliding slot 511 and the second sliding slot 521 in this embodiment may also be disposed on the reflector body 31, and the angle of the reflector 3 is adjusted and fixed by a rotating shaft disposed on the connecting member 5, which is not described herein again.
