研究了线结构光传感器的数学模型，并给出了齐次坐标系下的表达形式。根据线结构光传感器的特点，提出了一种用简单的齿形靶及一个一维工作台实现求光平面在摄像机坐标系的位置参数的高准确度的测试方法，解决了对抽象光平面的瞄准问题。通过实验验证，证实了这种测试方法的可行性。
The mathematical model of linear structured light sensor is studied, and the expression under homogeneous coordinate system is given. According to the characteristics of linear structured light sensor, a test method of high accuracy for obtaining the position parameters of the light plane in the camera coordinate system by using a simple toothed target and a one-dimensional workbench is proposed. Aim at the problem. The experimental verification proves the feasibility of this method.
