Applying 3d Affine Transformation and Least Squares Matching for Airborne Laser Scanning Strips Adjustment without Gnss/imu Trajectory Data

Abstract

In this article we extend our previous work on the topic of ALS strip adjustment without GNSS/IMU trajectory data. Between overlapping strip pairs the relative orientation as a 3D affine transformation is estimated by a 3D LSM approach, which uses interpolated 2.5D grid surface models of the strips and the entire strip overlap as one big LSM window. The LSM… (More)
