| Abstract: | A new non-contact measurement system for micro size based on CCD image is put forward. The non-contact measurement principle for geometry of part using image measurement technology is introduced. The main measurement approaches include: image collecting,image pre-processing, image binaryzation, edge detection and system calibration etc. The system measuring micro accessory geometrical size by non-contact method are designed and the components of the system, the key technology and the actual measuring experiment are explained. The measurement precision is analyzed. The results of the practical measurement show: the method is correct and feasible. |
