摘　　要：目前复杂环境下光斑移动目标定位误差大,无法从复杂环境下提取目标对象,导致光斑移动目标定位效率较低,因此,提出了复杂环境下光斑移动目标定位方法。采用无人机激光扫描技术,计算光斑移动目标方位角,根据关键点计算初始坐标,输出无人机的光斑目标定位结果,构建三维地图更新光斑移动位置,利用高斯分布模型建立光斑移动数学模型,结合重心法完成光斑移动目标的定位。实验结果表明,所提方法的光斑移动目标定位误差率仅为2%,光斑移动目标定位耗时为10 s,为实现光斑移动的准确定位提供了关键依据。At present,the positioning error of the spot moving target in a complex environment is relatively large,and the target object cannot be extracted from the complex environment,which results in a low positioning efficiency of the spot moving target.Based on this,a method for locating the light spot moving target in a complex environment is proposed.Use the UAV laser scanning technology to calculate the azimuth of the spot movement target,calculate the initial coordinates according to the key points,output the spot target positioning result of the UAV,construct a threedimensional map to update the spot movement position,and use the Gaussian distribution model to establish the spot movement mathematical model.Combined with the center of gravity method to complete the positioning of the spot moving target.The experimental results show that the positioning error rate of the moving spot of the proposed method is only 2%,and the positioning time of the moving spot is 10 s,which provides a key basis for the accurate positioning of the moving spot.
