一种基于Blob分析的摄像头模组缺陷检测方法

摘要

According to the defect detection of the traditional artificial of the camera module, it put forward a method based on the Blob analysis of the camera module. On the basis of the characteristic of the camera sensor, we design a special optical system, it can get the distinct and the requirement of the image. At the same time, using the Blob analysis algorithm to detect the dust of the sensor, then we conduct two consuming and the compared with the Microsoft experiments. The result is that the optical system by myself can be satisfied with the needs of the detection, and the efficiency is about 99.7%, and the method can meet the requirement of the detection of the camera module.%针对传统的摄像头模组灰尘人工检测方法的不足，提出了一种基于Blob分析的摄像头模组灰尘检测方法。根据摄像头模组图像传感器（Sensor）的特性，设计了专用的光照系统，获得清晰、满足要求的图像。同时采用了基于Blob分析对摄像头模组Sensor灰尘颗粒进行检测，通过检测的耗时性以及与金相显微镜精度对比，实验结果表明：自行设计的光照系统能够满足Sensor上污点的检测，同时运用Blob分析法对摄像头模组Sensor检测方法的效率较高，该方法能够满足摄像头模组缺陷检测的要求。
