AI Technical Summary

Technical Problem

Existing CCD vision testing modules lack light source illumination during testing, resulting in insufficient reflected light intensity on the surface of the tested object, low image contrast, and difficulty in distinguishing target features from the background. This is especially true for objects with similar colors or complex surface textures, making feature extraction difficult.

Method used

A CCD vision testing module was designed, including a light source assembly. The LED ring light is conveniently installed and removed by adsorption between a magnet and an iron block, providing uniform illumination. The support rod and sliding frame structure allow the CCD module to be adjusted and fixed in the vertical direction, and precise adjustment is achieved by combining locking screws and dimension lines. It is also equipped with a housing frame for protection.

Benefits of technology

It ensures the accuracy and clarity of visual testing, can clearly acquire image information, adapt to different testing needs, avoids the difficulty in distinguishing target features due to low image contrast, and meets the testing requirements of different tested objects.

Abstract

The utility model belongs to the field of visual testing, particularly relates to a CCD visual testing module, and aims to solve the problems that an existing CCD visual testing module is low in image contrast, difficult to distinguish target features and background and poor in testing accuracy due to the fact that the existing CCD visual testing module is not provided with a light source for illumination in the testing process and the reflected light intensity of the surface of a tested object is insufficient. In order to solve the problem of difficulty in feature extraction of objects with similar colors or complex surface textures, the utility model provides the following scheme that the device comprises a test board, a supporting rod is welded to the top side of the test board, and a sliding frame is arranged on the outer wall of the supporting rod in a sliding and sleeving manner. When the LED annular lamp is used, the LED annular lamp can be conveniently mounted and dismounted on the mounting ring, a good illumination condition can be provided for the CCD module, the accuracy and definition of a visual test are ensured, the problems that the image contrast ratio is low and target characteristics and background are difficult to distinguish are solved, and meanwhile image information of a tested object can be clearly collected; the image of the tested object under different conditions can be obtained, so that different test requirements can be met.
