General / no tie points on road surfaces
« on: April 28, 2023, 06:07:14 PM »
For awhile now, every time I fly an area with blacktop/roads, almost no tie points are found on the road surface. The dense cloud always looks like boiling tar on the roads. This even goes for roads that are significantly degraded with lots of patch work which should provide plenty for the SFM to grab on to (lots of contrast). Anyone have the same experience? My settings for align photos is shown in one of the attached photos. I've also attached one of the images from the flight. Attached is an image of the sparse cloud over the road where you can see there are almost no tie points. over lap 70%, side lap 75%. No issues with point cloud or accuracy anywhere else other than road surfaces. I feel like I'm just missing a setting or something.
