Hi @ja.pelaez, thanks for bringing this up.
My answers below:
Accuracy values for pictures
Right now, when there is no information in the EXIF/Xmp of the images about the horizontal and vertical accuracy of the pictures, default accuracy values of 5m (horizontal) and 10m (vertical) are set like in Pix4Dmapper.
If the recommended EXIF/Xmp tags for horizontal and vertical accuracy of images are available, then these are read and used instead of the default values.
These are the tags regarding accuracy:
for geolocation: Xmp.Camera.GPSXYAccuracy and Xmp.Camera.GPSZAccuracy
for orientation: Xmp.Camera.IMUYawAccuracy, Xmp.Camera.IMUPitchAccuracy, Xmp.Camera.IMURollAccuracy.
All EXIF/Xmp tags read by Pix4Dmatic are listed here: EXIF and XMP tag information read by Pix4D – Support. As long as the required tags are in the images, the camera is compatible with Pix4Dmatic, more in Which cameras are supported in Pix4Dmatic – Support.
Note that we are working on a .csv import of geolocation and orientation data, that will help set new values for the accuracies if they are not available in the Xmp data of the images. Once this import is available, we will also work on a table that shows all the geolocation and orientation data, so that this workflow becomes more transparent.
Quality report: absolute and relative geolocation variance
Here is the current content of the quality report: Quality report - Pix4Dmatic – Support
The values you are asking are not available for the moment, but we plan to work on a more extensive quality report. Your request is noted. Do you have examples when these values are particularly useful? This will help illustrate the need for these values.
