摘　　要：针对当前手机屏幕划痕检测存在的检测精度低,主观性强等问题,提出了一套定量检测方法。通过边缘检测算法得到划痕区域轮廓,在测量划痕区域像素点累加求出划痕面积;采用Rosenfeld细化算法求出弧长。实验表明,系统对划痕区域面积和弧长的检测精确度均可达98%以上。In view of the low detection precision and subjectivity in the current screen scratch detection of mobile phone screen,a quantitative method is proposed. Getting the contour of the scratched region by the edge detection algorithm.The area scratched is measured by adding pixels.The Rosenfeld thinning algorithm is used to obtain the scratched skeleton and then the arc length is obtained. The experimental results showed that the detection accuracy of the area and arc length of the scratched area can be more than 98%.
