Hi,
My problem occure with a scene where I used georeferenced targets (surveyed with a tacheometer) to georefence my 3d model.
First, I have run photoscan to align, build geometry and produce texture with my set of images.
The process goes to the end producing a quite good 3D model.
The geometry seems to be accurate.
Then, I switch to the ground control markers creation mode to create the markers on my targets to next declare the real coordinates.
So, I create the markers by pointing them on the photographs where they are visible.
Looking to the markers in the point cloud, it seems that some markers are well positioned whereas others are completely at a wrong place...
Then, when I set the georefenced coordinates, the result is not good (looking for the alignment of different 3D models supposed to be all georeferenced in the same system).
Finally, the problem seems associate with the misplacement of some markers.
I could only keep the markers that seems well placed but doing this I wonder if my model is really accurate. Moreover, the georeferencing seems remaining inaccurate when I look to the others georeferenced parts.
Does someone have encountered the same issue ?
And what can I do or test ?
Thank you in advance for your help.
