#742: v.coregister / v.align : A module to translate and rotate a point cloud to best match one another --------------------------+------------------------------------------------- Reporter: stevensj | Owner: [email protected] Type: enhancement | Status: new Priority: normal | Milestone: 6.4.0 Component: Vector | Version: unspecified Resolution: | Keywords: lidar, point, cloud Platform: Unspecified | Cpu: Unspecified --------------------------+------------------------------------------------- Comment (by helena):
Replying to [ticket:742 stevensj]: > Often LiDAR data is collected as strips (e.g. airborne), or point clouds with different sources (e.g. ground-based). When the two files are combined they might be slightly offset, resulting in nasty artefacts. It would be excellent to have a module that would allow one point cloud to be adjusted to best fit another one. The same module would also be able to pin a dataset to ground control points. .... We have just started to look into this - we have ground based laser scanner and we need to co-register multiple scans in 3D and we also work with a lot of airborne data (although the newest data usually come gereferenced pretty accurately). Please email me (hmitaso at unity.ncsu.edu) so that we can exchange more details about the potential module and the best methods for the task.
