Improving comsumer grade GPS referenced model with known scales

PIX4Dmapper PIX4Dmapper Questions/Troubleshooting
1

Hi all.
Im aware that using consumer grade GPS referenced photos, the accuracy of the project is limited to the accuracy of the GPS (1 to 5mts). Also Ive seen theres a way to manually scale a project with a relative coordinate system and creating manual GCPs with known distance. Issue is that If one chooses a relative coordinate system, the model will not be geo referenced at all (not even with the 1-5 meter precision). Is there a way to mix this methods to improve the inner accuracy without loosing the geo referenceing?

thanks!

Hi Maximo,

your problem is solved with the new Pix4Dmapper version (2.0). I had exactly the same problem.
The new 2.0 version has the scale constraints tools. Check the video that Olivier did: https://www.youtube.com/watch?t=501&v=3RJwV40ehGs with the new features.

hope it helps,
Marc
