线结构光传感器标定点获取方法研究

Method for acquiring characteristic pointsin the calibration of line structure-light sensor

提出了一种基于双重交比不变性的线结构光传感器标定点获取的方法 ,利用该方法和设计的标定靶标 ,可方便的获取大量的高精度的标定点 ,解决了线结构光传感器标定点不易产生且数量少的问题 ,从而可以在一定程度上提高标定的精度 .

Based on the cross-ratio invariance theorem, a new method for acquiring characteristic points in the calibration of line structure-light sensor was proposed. A larger number of high precision characteristic points were easily acquired using this method and the designed calibration target. The problem that it is difficult to acquire a lot of high precision characteristic points was resolved and the calibration precision was improved. The simulation results verify the feasibility of this method.
