VISION TESTING DEVICE WITH ENHANCED IMAGE CLARITY

摘要

The vision testing device of the present invention is a vision testing device with enhanced image clarity for discriminating a satisfactory or a non-satisfactory testing object by shooting a testing object assembled or mounted during a component assembly process, and comparing the image taken with a previously inputted target image, and comprises: a stage part for fixing or transferring the testing object to the testing location; a lighting part located on the upper portion of the stage part, for providing lighting to the testing object; a first camera part located in the center of the lighting part, for obtaining a 2-dimensional image of the testing object; a second camera part placed in plurality on the side of the first camera part; a grid pattern irradiating part placed between the camera of the second camera part and a camera; a vision processing unit for reading the image taken in the first camera part and the second camera part, and discriminating whether the testing object is satisfactory or non-satisfactory; a control unit for controlling the stage part, the light irradiating part, and the first and the 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.
