摘要
本文针对传统正射影像数据处理产生的多重映射及纠正变形等问题,提出了一种新型的真正射影像生产方法。该方法通过对初始点云的修测与编辑,识别出相邻像素中的可见影像,并使用射入角最小的原始影像进行拼接。通过临淮岗复线船闸工程实际应用的结果表明:本文所提出的真正射影像的生产方法既可以解决传统正射影像制作中存在的多重映射与纠正变形等问题,还可以提高正射影像成果的精度。
Aiming at the problems of multi-mapping and distortion correction caused by traditional orthophoto data processing, a new real production method of orthophoto image is proposed in this paper. By modifying and editing the initial point cloud, the visible image in adjacent pixels is recognized, and the original image with the smallest injection angle is used for stitching. The results of practical application of Linhuaigang double-track lock project show that the real image production method proposed in this paper can not only solve the problems of multiple mapping and correction of deformation in traditional orthophoto image production, but also improve the accuracy of orthophoto image results.
