Hello
I have PhotoScan Pro and I'm trying to scale a model with mesh and texture to the right size.
The model consists of several buildings and some ground between them with different elevations. I used 2206 cameras (mostly TIFF images with gps EXIF) and some jpg images taken from 4k video (without EXIF).
The model looks great - dense cloud is wonderful with 61M points. The mesh looks great with 90M faces. After 3 weeks of processing (aligning, generating dense cloud) I took a good gps unit with waypoint averaging to the site and took 6 samples of several locations. Then I placed 15 markers in the model and set the flags in most of the 2000+ cameras.
I have created 10 scale bars using the markers and set the distance in meters. I also set the GPS lat, long, and alt for 3 of the markers.
The EXIF information in the TIFF images came from a DJI Inspire and contains gps information in WGS. I also set the marker GPS information manually using WGS coordinates. I clicked 'update'.
No matter how many times I click 'update' and/or 'convert' , when I save the model as a obj or ply using 'Local Coordinants', the resulting saved model appears in GeoMagic and Meshlab as being 19mmx51mmx48mm in size.
Even worse, if I save the model as 'WGS-84' coordinates, the resulting model is only a straight vertical line of a few points that doesn't even appear in my textured model anywhere.
I cannot figure out how to save the model in a way that MeshLab or GeoMagic knows about the correct scale.
The reason I care about having the saved model be the right size is because I'm trying to merge the fantastic Photoscan model I created with point cloud data captured from a laser scanner. The laser scanner is very accurate and I want to get my Photoscan model the correct size using my gps coordinates and measured markers so it fits together with the laser scanned data.
Can someone help me out with this?
Thank you very much!!
