I’m currently doing a masters thesis, using ODM to generate a 3D point cloud and compare various different vegetation structure parameters to field measurements.
Part of my research involves a quality assessment of the ODM outputs, using both a qualitative assessment and the ODM report.
I have a question about a drone flight I did yesterday. I flew the drone in perfect conditions, with a flight plan and settings to maximize quality. The outputs look great, except for one thing, the ODM quality report states that “Reconstructed Points (Sparse) 647799 over 4818886 points (13.4%)”
Unless I am confused, that seems very low? Even though in all other aspects the quality of the outputs seem quite good.
Can anyone help me make sense of this? See dropbox link to the report below
