Description

technical field [0001] The invention belongs to the technical field of automatic optical detection, and in particular relates to an image acceleration processing system suitable for LCM automatic optical detection. Background technique [0002] At present, TFT-LCD production testing is mainly manual, to ensure that NG products are not allowed to flow out and to avoid excessive screening, so as to avoid material waste and cost loss, which requires more eyesight, energy and patience of workers. With the improvement of the resolution and size of LCD panels, it is difficult for human eyes to distinguish some faint defects, and these faint defects cannot flow into high-grade products. In addition, under the requirement of output, production line workers need to quickly and uninterruptedly inspect the appearance of various screens or modules repeatedly, which is easy to cause visual fatigue, resulting in missed or over-inspection. At the same time, in order to save labor costs, v...

[0005] 2) With the increase in the number of cameras for taking pictures, the amount of image calculation data has correspondingly increased sharply. The data size of a picture taken by one CCD is usually about 30MB, and a panel inspection needs to take about 15-20 pictures; Therefore, the amount of image data to be processed by each panel is as high as several T;

[0007] 4) A traditional PC or multiple PCs can no longer cope with the calculation and processing of such a large amount of data
