| 摘 要： | 针对传统的自动焊线杌采用模版法进行LED微芯片检测速度慢、效果不理想的问题,提出了一种无需模版的检测方法.该方法首先进行图像分割和改进的中值滤波处理,然后采用自适应阈值算法将图像二值化,再利用邻域检测将图像中的微芯片适当加权,最后通过质心定位微芯片.部分可并行化的操作(改进的中值滤波、加权操作)利用GPU并行运行,提高...

| Abstract: | As the traditional method of using templates to LED microchip detection with low efficiency,this paper proposes a detection method without template.First image is divided and improved median filtering processing,secondly to adopt new adaptive threshold algorithm binary image.Thirdly,the image is weighted by the neighborhood detection,finally through calculating quality center localization microchip.Then use GPU makes the whole operation parallelization to accelerate positioning speed.Experimental results sh... |
