线结构光传感器结构参数标定的新方法

A NEW TECHNIQUE TO CALIBRATE THE STRUCTURED PARAMETERS OF THE LIGHT-STRIP SENSORS

摘要: 本文提出了一种简单、快速、高精度的线结构光传感器结构参数的标定方法．为求得光平面和摄像机间的位置关系，设计了一种简单、实用的梯形靶标，以测量光平面上点的坐标，并采用罚函数约束求解参数．该方法对可见光和不可见光的场合均适用．实验证明，这种方法具有较高精度．

Abstract: This paper describes a new method for the accurate calibration of the line structured light visual sensors.In order to get the relationship between the light-plane and the camera,we design a simple and useful toothed target to measure the point on the light-plane.Then we use a punishing function restrained calibration method to caculate the parameters.This method applies in both visible and invisible light.
