A 3D Color Measurement System

This paper describes a novel 3 dimensional color measurement system. After the sensors and corresponding data processing board were presented, based on a calibration board with right-angled triangle outline, two calibration algorithms are presented to obtain the extrinsic parameters for sensors. One is the calibration algorithm between 2 dimensional laser range finder (2D LRF), the other is for 2D LRF and the color camera. The result parameters were obtained through solving the constrain equations by the correspond data between the 2D LRF and other two sensors. The 3D color reconstruction experiments of real data prove the effectiveness and the efficient of the system and the algorithms.
