摘要
针对大气环境下激光光斑瞄准偏差的问题,设计了激光光轴偏差测试系统,讨论了大气环境中由于诸多因素的影响而导致激光光斑几何中心与目标中心发生偏移而不能对准的现象。提出了数字图像处理技术与重心法相结合的一套新的偏差补偿算法。充分利用激光光斑全场数据,从理论和实验上对大气环境下的激光光斑瞄准偏差进行了分析和研究。外场实验结果表明,该方法可以对瞄准偏差进行有效补偿,具有较高的工程应用价值。
According to the problem of pointing error of laser spot in atmosphere environment, the laser axis error measuring system is designed. The phenomenon of the deviation between the geometric center and the target center of the laser spot because of the influence of various factors of the atmospheric environment are discussed. A new error compensation method by using digital image processing technologies and baryeenter method is proposed, and adequately using laser spot full-court data,the laser spot pointing error is studied theoretically and experimentally. The outfield experimental result shows that the method can make effective compensation to the pointing error. The proposed compensation method is shown to be valuable in engineering.
