I am trying to produce some orthomosaic, but I have some problemes near roof edges. For example, I have produced a perfect DSM using 3rd party software that look like this:
Because it is not possible to import DSM directly to Pix4D and produce ortho using my own DSM, I need to convert above DSM to point cloud and import this point cloud to Pix4D. Converting a raster DSM to point cloud is not really difficult using for example GlobalMapper, The problem is when Pix4D tries to reconvert point cloud to its usable DSM, it rounds edges, something like this:
And this DSM causes to produce a bad ortho. like this:
As you can see there are some movements near bottom edges, and some rounded edges around it.
Anybody any solution?
