Strip alignment (also known as strip adjustment) can help improve the consistency between several adjacent UAV-LiDAR flight lines. Strip alignment workflows utilize algorithms which align the LiDAR point clouds from one strip to another without necessarily knowing the source of the error.
1- Image matching and finding tie points
2- Relative Orientation triangulation
3- Absolute Orientation with 3D conformal and M34 method
4- You can also choose different matching method or orientation method to run the code
