Abstract The camera intrinsic parameters in digital close-range photogrammetry were studied.The imaging and distortion model were analyzed.Then,the camera intrinsic parameters were calibrated with the method based on plate pattern.A multi-feature plate pattern was designed according to the application and the characteristics of the system.Furthermore,a corner detection function suit for the plate pattern was coded after analyzing the detecting algorithm. At last,an experiment was carried out to examine the plate pattern and the detection function.The average error in corner detecting was less than 0.02 pixel in this examination.

Key words： Metrology Digital close-range photogrammetry Intrinsic parameters Standard pattern;Corner detection
