All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
Referring to fig. 1 and 2, a mosaic tile image capturing apparatus includes: conveyer belt 100, the box 200 that shades, industry camera 300, light source board 500 and polarizer 400, conveyer belt 100 passes through the control of operating mode machine 700, the box 200 that shades sets up in the top of conveyer belt 100, the diapire fretwork of the box 200 that shades can erect the box 200 that shades through the support for the bottom of the box 200 that shades has certain distance with the transfer plane of conveyer belt 100. The light shielding box 200 is provided with a polarizer 400 and an industrial camera 300, wherein the left side of the polarizer 400 is connected with the left inner wall of the light shielding box 200, and the right side of the polarizer 400 is connected with the right inner wall of the light shielding box 200. The connection mode of the polarizer 400 and the light shielding box 200 can be realized by arranging grooves on the left inner wall and the right inner wall of the light shielding box 200, and the polarizer 400 is inserted into the grooves in a slot mode. By this mounting, the polarizer 400 is conveniently mounted and dismounted. The industrial camera 300 is fixedly connected with the upper inner wall of the light-shielding box 200. In the positional relationship between the polarizer 400 and the industrial camera 300, the polarizer 400 is disposed obliquely and forms an angle of 45 ° with the transmission surface of the transmission belt 100, the industrial camera 300 is located above the polarizer 400, and the main optical axis of the lens of the industrial camera 300 forms an angle of 45 ° with the polarizer 400.
