| 摘 要： | 为了在探测图像中实现对激光光斑的精确定位，进而达到系统对激光光源精确定向的目的，引入了亚像素检测的算法.并针对小同大小的光斑分别采用了重心法和基于空问矩的综介检测方法.进行了理论分析和实验验证.取得了小同光强下光斑坐标均值和均方差数据。结果表明.这种方法在扩展检测动态范围的基础上可以使激光光斑定位精度达到在0.2个像素以内。这一结果对保证系统对激光源的精确定向是有帮助的。

| Abstract: | Laser spot detection is the key technique in the imaging laser detecting system.In order to find the pinpoint direction of the laser source and locate the accurate laser spot position,the arithmetic of sub pixel measurement was put forward.For different laser spots,it was studied with the method of gravity model and the method based on spatial moments both in the theory and experiment.The statistic data of the mean value and root-mean-square of the spots' coordinates at different laser intensity approved th... |
