An arched through hole 22 is opened on the baffle plate 43. The arched through hole 22 extends to one end away from the top cover plate 41, and the product passes through the arched through hole 22. Furthermore, the height of the baffle plate 43 is shorter than that of the camera cover plate 42. The height of the baffle plate 43 can pass through the conveyor belt below, so at the opening of the cover body 2, the distance between the baffle plate 43 and the conveyor belt plane is smaller than the distance between the camera cover plate and the conveyor belt plane, and the conveyor belt drives the product through the baffle plate 43. The length of the baffle plate 43 is relatively short, which can prevent the bottom of the baffle plate 43 from contacting the conveyor belt, thereby not affecting the transmission of the product. In addition, 5 cover plates 4 are arranged above the conveyor belt, and a conveyor belt is arranged at the opening at the bottom of the cover body 2. Therefore, the cover body 2 and the conveyor belt can jointly constitute a shooting space, and the through holes on the 5 cover plates 4 are adapted to the camera group 1 and the product, which can further reduce the impact of external light on the internal shooting space.

[0034] It should be noted that, refer to Figure 4 The cover body 2 of this embodiment can be installed on a straddling rack, which includes a supporting frame, which includes a first supporting frame and a second supporting frame, which are symmetrically and non-contactly arranged on both sides of the conveyor belt, and the height of the first supporting frame and the second supporting frame is higher than the height of the conveyor belt. Crossbars are arranged on the first supporting frame and the second supporting frame close to the height of the conveyor belt, and multiple crossbars are evenly installed around the height of the conveyor belt. The crossbars are connected by a mounting plate, and the sliding mechanism connected to the camera assembly 1 is fixed on the mounting plate. The top ends of the support bars of the first supporting frame and the second supporting frame that are farthest apart are laterally arranged with support bars. The beam connects the first supporting frame and the second supporting frame to form a frame as a whole that spans the conveyor belt. In the cover body 2, two camera covers are respectively installed on the first supporting frame and the second supporting frame, and two shielding plates are connected to the first supporting frame and the second supporting frame. The top cover is connected to the top of the camera cover and the shielding plate to form the cover body together. The spanning frame provides support for the camera group 1 and the cover body 2.
