VISION TESTING DEVICE WITH ENHANCED IMAGE CLARITY |
摘要 |
<p>The vision testing device of the present invention is A vision testing device with an enhanced image clarity for determining good or bad of a testing object by photographing a testing object assembled or mounted during the component assembly process and comparing the photographed image with a previously inputted target image, comprising: a stage part for fixing or transferring the testing object to a testing location; a lighting part for providing lighting to the testing object located on an upper portion of the stage part; a first camera part for obtaining a 2-dimensional image of the testing object located in a center of the lighting part; a plurality of second camera parts placed on a side section of the first camera part; a plurality of grid pattern irradiating parts placed between cameras of the second camera parts; a vision processing unit for reading the image photographed by the first camera part and the second camera parts and determining good or bad of the testing object; a control unit for controlling the stage part, the grid pattern irradiating parts, and the first and second camera parts; and a light diffusion part. The present invention enhances the uniformity of light being irradiated on the surface of the testing object. In addition, the present invention enables a more clear shooting of an image by removing a half mirror placed on the front of a camera part in the center, and enables convenient maintenance by miniaturizing the size of the device and dispersing the configuration.</p> |
