Paper Abstract

A mono-camera based calibration method for laser ranger finder (LRF) combined with a two-axes turntable measurement system is proposed in this paper. The LRF rotates around the two axes and two parallel calibration planes are used to intercept a laser beam in order to calculate the manually-set output point of the LRF. The space coordinate of the two laser beam spots is computed using monocular vision method. Then the manually-set output point of LRF is calculated based on the principle of light propagating linearly. At last multiple manually-set output points are collected to fit the axis parameters. The space coordinates of targets can be calculated by LRF measurement system through accurately calibrating the two-axes of the turntable. A quantitative experiments show that the measuring precision of the system is within 0.5mm. Our calibration method is simple, effective can be extended in other measuring system with a single, two and more axes turntable.
