| Abstract: | Along with the rapid development of production and science technology,the demand of precision,stability,efficiency and automation degree of CPU connecting pores detection is higher and higher.This paper proposed a method of CPU size detection based on closerange photogrammetry.By taking pictures of CPU connecting pores,we got their photographs,then used efficient template matching algorithm to extract the CPU slots and extracted the margin of CPU slots with improved Canny operator.At last,according to the geometry and gray characteristics,we measured the sizes of pores precisely to realize the detection of CPU connecting pores. |
