A solar cell detection method and system

Abstract

The application discloses a kind of solar cell detection method and system, utilize strip light source and area array camera to collect multiple frames solar cell image, multiple frames solar cell image is spliced to obtain the solar cell image to be detected, the solar cell image to be detected is carried out gamma correction, obtain the solar cell image to be detected after correction, the solar cell image to be detected after correction is carried out defect detection, through strip light source and area array camera acquisition, camera and light source cost are greatly reduced, and equipment installation space is saved, and because area array camera resolution is lower, image detection time can be shortened, improve detection efficiency, simultaneously using image splicing and gamma correction to optimize image, improve the uniformity of image overall brightness, can guarantee higher detection rate and lower misjudgment rate, ensure the accuracy of detection result, to improve the economy, efficiency and flexibility of detection under the condition of guaranteeing detection accuracy.
