AI Technical Summary
Technical Problem
During screen testing, it is difficult to distinguish between foreign objects and dead pixels, resulting in low detection accuracy.
Method used
By acquiring the first detection image of the screen, the diameter and number of abnormal points are determined. The shooting angle is adjusted to acquire the second detection image. The number and position of abnormal points in the two images are compared to screen defects. Non-defective points are screened out, and duplicate detection points are identified as screen defects.
Benefits of technology
It improves the accuracy of screen dead pixel detection and reduces the number of non-dead pixels being misidentified as dead pixels.

Abstract
本申请公开了一种屏幕坏点的检测方法、检测设备及存储介质，涉及屏幕缺陷检测技术领域，公开了屏幕坏点的检测方法，包括：获取基于待检测屏幕采集的第一检测图像，并确定第一检测图像的异常点的直径尺寸和数量；若直径尺寸小于或等于预设尺寸，数量小于或等于预设数量，调整待检测屏幕的拍摄角度，并采集待检测屏幕的第二检测图像；若第一检测图像的异常点数量大于第二检测图像的异常点数量，确定第一检测图像和第二检测图像之间的重复检测点为屏幕坏点。对不同拍摄角度采集到的两张图像进行分析，以异常点数量为基准选定图像之间的重复检测点作为屏幕坏点，通过异常点数量进行分析，减少反光、灰尘等干扰导致的误判，提升检测准确率。
