General / Getting Artifacts around buildings and other structures in Orthomosaic
« on: June 20, 2022, 04:22:15 PM »
Hi,
I have tried considering these settings while processing orthomosaic.
Build ortho : geographic
Surface : DEM
Refine seamlines = checked
Enable hole filling = Checked
Enable Ghosting Filter = unchecked
Refine Seamlines checked and unchecked doesn't show much changes.
I have also tried Point cloud classification and genarated DEM using only Ground points but there is much X Y shift between the building edgs and problem of lean edges.
I cannot manually draw the patch for each buildings for seamline correction because I have around 10 thousand buildings in my ortho.
I have attached few screenshots of ortho. Kindly suggest some good settings so that we can avoid artifacts. I have the flight overlap of 75 front and 80 side of each image. And camera resolution is 24MP.
