基于网格的多目标模板匹配晶粒位置检测方法
Grid-based Multi-targets Template Matching Die Position Detection Method
摘要
Abstract
To address the limitations of traditional methods in terms of long detection time and low accuracy,a multi-objective template matching algorithm detecting position of die based on grid is proposed.By improving the traditional template matching method and combining with non-maximum suppression algorithm,the detection speed and accuracy of chip dice are improved.Experimental results show that the proposed algorithm has a recognition rate of over 97％for a single same die,and the single image processing time does not exceed 200 ms.It can overcome the detection difficulties caused by different brightness and meet the technical specifications.关键词
