Image Quality Troubleshooting
If you observe poor image quality during the spot check or if you receive error
messages during processing, use the settings below to troubleshoot the image
quality.
Blurry Images
To correct motion blur, adjust the shutter speed using the
Target Tv
parameter in the
script menu.
Target Tv
(shutter speed) default:
1/1250
To correct moderate motion blur:
Set to 1/1600.
To correct severe motion blur:
Set to 1/2000.
Overexposure
If the images are overexposed but do not show any motion blur, it can be due to
flying in extremely bright conditions. To correct this, set the
Allow use of ND filter
parameter to YES in the script menu.
Allow use of ND filter
default:
No
To correct overexposure:
Set to Yes.
Processing Errors
If you receive errors from Pix4Dmapper during processing, increase the overlap and
sidelap during survey configuration to improve the quality of the image set.
Overlap
default:
50%
Sidelap
default:
60%
To improve processing:
Set overlap to 60% and sidelap to 70%.
