Abstract: In this research, we propose a two-axis dual-CCD image-servo shooting platform as a development principal basis, which adopts dynamic target tracking method and image processing technique to search, detect and identify the intruding target and execute a continuous tracking action. Herein, we use the architecture of dual-CCD cameras as the basis of the stereo vision construction to find the actual 3D spatial coordinate of target through eliminating the radial and horizontal offsets of camera by using camera calibration technique. Based on the geometric relation and the pixel difference between the dual-CCD images, we can calculate the precise spatial coordinate of target in the dual-CCD coordinate. From the experimental results, the precision of target hitting in dynamic target tracking mode can be promoted to 5mm.
