General / Combining Laser scan and point cloud data
« on: January 18, 2022, 12:55:37 PM »
I've read that it is possible to combine laser scanned point cloud and UAV photo data.

I have a large point cloud of a building in e57 format uncolored and a set of geotagged photos of the roof and yard area in colour. These photos also have targets if necessary. The Geotags are in WGS84 but the cloud is in a local coordinate system. The cloud is registered but not unified.

Can someone point me to a straightforward workflow to combine this data. Do I need to process the photo data to a dense cloud first? Do I need to add the target points to the scan data? Any help would be greatly appreciated.

General / Dense point cloud not as good as earlier Agisoft version

Checking back on an old roof survey job, I processed the photos and it seems that the dense point cloud has many holes where none previously existed. Can anyone explain why this might be happening and how the quality can be improved. I've noticed similar results on other jobs but this is my first like for like comparison between old agisoft and new metashape.

General / Problems with shapes/vertex markers
« on: January 26, 2021, 02:02:09 PM »
Since installing the latest versions of metashape, when  I draw a shape on a cloud, model or DEM the program displays the vertices as 'flag' markers. Also I can't change the shape outline without adding a new vertex whereas in the older versions I could just drag on old vertex to the preferred position. Does anyone know how this can be changed back to the older settings?

Camera Calibration / Working with Material from a Different Camera
« on: December 09, 2019, 08:51:35 AM »
I've been tasked with processing material from a different drone from a third party provider. The camera will obviously be different from the one that we regularly use.
Will I need to do any adjustments to agisoft before processing the material?
