Research on measurement method for disk cam based on image processing technology
摘要
Abstract
To satisfy the demand of online detection,a new measurement method for disk cam based on image processing technology is proposed.First of all,the image is preprocessed with enlarging,morphological filtering,smoothing,threshold segmenting and object extracting,and the binary image of the disk cam is obtained.Secondly,the image is preliminarily adjusted according to the minimum bounding box of the inner contour,fine-tuned based on precisely linear fitting,to place the disk cam in proper position.Finally,the coordinates of the disk cam's rotation center is calculated,and points in the outer contour of the disk cam are sampled to compared with design values,and the result is output after detection.The results show that it can satisfy the requirements of online detection owing to its high efficiency and simplified operation.关键词
