A Flexible and Accurate Calibration Method for Line Structured Light

Line structured light calibration establishes the relationship between the camera and the laser plane. Different from conventional calibration algorithms, the proposed method needs only one scan of the stair block, and then we can obtain the optimal laser plane function. We first demonstrate our line structured light system's mathematical model. Secondly, a constrained nonlinear multivariable function is constructed with the aid of the stair block. Finally, we can obtain the optimal laser plane function by solving the optimization function. In the experimental section, Our calibration method is proved with high accuracy and flexibility by several experiments.
