Abstract: A novel non-contact, high accuracy and automatic area measurement method for cartridge surface ablation, which combines coordinates measurement with image detection, was presented. Basic requirement of design is to improve the measuring speed possibly under the prerequisite for ensuring expected measuring accuracy. Some key structures and parameters of the system components were de?signed .The corresponding measures were taken to ensure accuracy during scanning and mosaicing the surface of cartridge. An imaging system with manual adjustable parameters was selected, and the ve?racity of irregular ablation region segmentation was greatly increased using a gray unbalance method. Experiments and practical applications show that this method is reliable with certain accuracy and high efficiency for the area measurement on curved surface.
