Global calibration for multiple cameras in profile measurement system based on light-sectioning method

摘要

A multi-camera global calibration method based on an LCD target and solid target with edges is proposed. Calibration and data fusion for the cameras are achieved in an unified world coordinate system. Extended abstract In 3-D surface profile measurement system with multiple cameras, the global calibration for the cameras can realize the mapping of the sampled data from image coordinates to world coordinates and determine the measurement precision. The system is required to respond rapidly and operate simply and expediently in industrial applications.
