本文在广义坐标系中采用投影和透视变换理论建立了网条结构光三维视觉检测模型。在此基础上 ,通过对网条结构光光条影像特征分析 ,提出了一种利用网条结构光光条影像特征标定三维视觉检测模型参数的方法 ,并进行了实验研究。该标定方法具有简单、有效 ,处理速度快 ,辅助设备少 ,易于实现等特点 ,在保证精度的同时简化了标定过程 In this paper, the projection and perspective transformation theory is used to establish a three-dimensional visual inspection model of structured light in a generalized coordinate system. Based on the analysis of the image features of light strips, the paper presents a method of using three-dimensional vision to detect the model parameters by using the characteristics of the light strips of the net structure, and conducts experimental research. The calibration method is simple, effective, fast processing speed, less auxiliary equipment, easy to implement and so on, to ensure accuracy while simplifying the calibration process
