Thanks a lot Alexey for your repley, I already done that. But, the issue is when I create markers, then imported the 3 known point (which supposed to be placed on one of there markers), but they are Not. Also, Could you please explain to me how to determine the rest of markers' coordinates (x, y, z) (20 markers) in Metashape? / is it possible to do it in Agisoft Metashape?
What I have done so far:
• loading photos into Agisoft Metashape
• removing unnecessary images;
• aligning photos;
• building dense point cloud; created 20 Markers
• building mesh
• generating texture;
• building tiled model;
• building orthomosaic
Then, I added the unknown points to the software, it appears in the tool bar, but not in the model (nor on the markers)
* I have 3 known point (were measured by Total Stations only).
* I used Solo 3DR Drone
* I do Not have Camera Position (GPS was not built with the drone I used)
