General / Smoothing boundaries between drone flight paths on DEM
« on: April 22, 2022, 02:56:00 AM »
I've created a textured model based on drone imagery and then built/exported a DEM in Metashape. However, there are pronounced ridges along the edges of my flight path areas, appearing as if showing the edge of a terrace. How can I smooth these seams/ridges? They should be apparent in the attached image. Any advice is appreciated!

General / Aligning and Merging Chunks of Drone Photos
« on: December 02, 2019, 05:05:17 PM »
I have 8000 photos split up into 28 chunks. Each chunk contains photos taken during a single flight session that someone else took for me. All photos in each chunk were aligned using GPS points/reference preselection. I haven't processed dense cloud in these chunks yet; only sparse cloud.

When I go to Align Chunks, I see a pair preselection option but not a reference preselection, which I was hoping for. But I can quickly merge all chunks (skipping the Align Chunks step) and it seems to overlap correctly because my cameras have GPS metadata. Now that I have everything in one chunk I can proceed as normal, correct? Move straight to Build Dense Cloud, skipping Align Chunks?


Hello! Thanks in advance for your help.

I have successfully produced a model from GPS referenced drone pics. Overall the model looks good. My bounding box is correctly around the model, with the red side below it. It is also in the correct UTM zone.

My question is: why are my predefined views tilted? If I select top (or bottom for that matter), it is shown at an angle instead, tilted, and when I export an orthophoto it too, of course, is tilted at the same angle. I need to export this as both a DEM and Orthophoto to import into a GIS. See image for tilt, shown using the "top" predefined view.

I seem to remember this happening before, but I use Photoscan irregularly and can't remember what I did to fix this before.

Thank you!
