I’m working on a detailed building scan, outputting orthofacade’s of each section of building exterior for inspection.
The process has been working quite well, until I ran into issues with some of the orthofacade’s outputting mostly black nothing, instead of the crisp outputs from the rest of the building. I’ve run a series of tests and determined that this is due to the shape of the building and the way that Pix4DMapper is handling the orthofacade generation. The section of the building I’m running into issues with is a “Y” shape, like so:
The first orthofacade worked great:
The second did not:
After adding in several more MTPs and re-processing to ensure I had a great densified pointcloud, I finally realized that the actual problem was that the south side of the building was “blocking” the orthoplane. Even thought the orthoplane clipping box does not intersect the the south side, the program seems to be projecting from much further back, resulting in occlusion from the south part of the building.
I confirmed that occlusion was the cause by angling the orthoplan for that section of the building to verify that it wasn’t the pointcloud that was the issue:
I’m wondering what the best option is to output a proper orthofacade of these areas of the building that are occluded by other sections?
