【摘要】：对遥测影像采用激光扫描匹配和配准,提高遥感对地探测的精度,传统的遥测影像匹配算法采用高分辨率SAR图像处理算法,实现对地遥测目标的特征融合检测,算法存在计算复杂,检测精度不高的问题。提出一种基于可变增益控制的遥测影像激光扫描匹配算法。构建遥测影响的三维影像数据提取模型,设计遥测影像对地探测的激光散射模型,采用激光扫描方法进行地理信息遥感标定,在尺度空间进行插值运算,进行遥测影像标定可变增益控制,准确实现对地理信息特征的激光扫描遥感标定。仿真结果表明,采用该算法进行遥测影像激光扫描匹配的准确率最高,提高对地遥感探测的目标识别能力。
[Abstract]:Laser scanning matching and registration are used for telemetry images to improve the accuracy of remote sensing to ground detection. Traditional telemetry image matching algorithm uses high-resolution SAR image processing algorithm. In order to realize the feature fusion detection of ground telemetry target, the algorithm is complicated. A laser scanning matching algorithm for telemetry images based on variable gain control is proposed. A 3D image data extraction model with telemetry effect is constructed. The laser scattering model of telemetry image is designed, and the remote sensing calibration of geographic information is carried out by laser scanning method. The interpolation operation is carried out in the scale space, and the variable gain control of telemetry image calibration is carried out. The simulation results show that the accuracy of laser scanning matching for remote sensing images is the highest, and the target recognition ability of ground remote sensing detection is improved.
