摘要
设计了一种由红外激光器和数字单目摄像头组成的非接触测距系统。该系统利用激光三角法对单目摄像头采集到的激光光斑图像进行位置信息处理,从而得到目标物离摄像头的距离信息。实验结果表明,该测距系统测量范围为2~100 cm,能对目标物离摄像头的距离及其大小进行准确测量,测量精度达到了毫米级。
The laser ranging system based on infrared laser and digital monocular camera was investigated.This system mainly performed the location information processing on the laser spot image collected by laser triangulation method in order to acquire the range information.The experimental results showed that the measurement of the ranging system could detected the distance varied from2-100cm,and it could measure both the distance and the size of the object,with a measurement accuracy reaching millimeter level.
