I have uploaded all the files into the drive.
The whole point is to be able to produce a correct DTM model/terrain profile/mosaic map for the whole area as uploaded in OneDrive. I have to use an open source method to produce the terrain model instead of relaying on results produced in pix4d for now.
Apart from having a problem with -ve contour/DTM, merging projects have been proven very difficult without GCPs (although i have many MTPs laying on overlapped areas but not calibrated when merged). I have repeated the merging efforts too many times and each time i have to delete and redo it again and again but to no avail. it’s very stressful and lost not knowing how to merge properly.
There are questions such as:
Before merging (on individual sub-project level):
- Should individual project’s camera setting remain original (not optimised) , & internal camera set to ALL (NOT ALL PRIOR), as long as they pass quality check. What if i change one of the sub-project’s internal camera to ALL PRIOR & also its loaded optimized camera setting (due to 90% relative difference in camera optimization). Would all these settings affect merged project’s accuracy? should them be corrected on the individual project level, or only correct them while merging the project?
- Should we change ALL sub-projects’ internal camera setting to ALL PRIOR for ALL, or only for those affected with misalignment of dots?
2.Should we also change camara optimisation for all back it ORIGINAL, or should be use
When it comes to merging, initially i came across a problem with misplaced red and blue dots on one of the sub-projects (total 5 to be merged), but it was resolved by changing all sub-projects’ internal cameras to “All prior”. Subsequently, i also changed the camera model back to original (instead of the optimized one) for all the sub-projects in the merging window. BUT this resulted in 4/5 sub-projects’ point cloud appeared in RED, forming RED sea, and failed.
I seriously need your team to look into those problems as i am hitting the wall now not knowing what to do next to improve DTM, & Merging.
TQVM and please help.
