Hi,

First I would like to inform you that if you need personal Pix4D support, you can buy our services “Support and Upgrade”:

Then regarding your projects, each of them have many blocks up to 18.
This is due a lack of matching between different blocks because camera could not properly calibrate.
It happens when the surveyed area is very homogeneous such as forest, desert, water.
Trees and dense vegetation often have a very different appearance between overlapping images due to their complex geometry (thousands of branches and leaves). 
Flying at a higher altitude often reduces visual complexity and improves the results, especially in forest and dense vegetation environments. At higher altitude, there is less perspective distortion (therefore causing less appearance problems) and the dense vegetation has better visual properties. In other words, it is easier to detect visual similarities between overlapping images in such areas.

For processing, I would recommend you to:

  • Reduce the images scale to 1/2 (even 1/4 if you cannot achieve better results).
  • Use “All Prior”
  • Rematch “Custom/Rematch”


  • Reduce the number of matches

Hope this will help,

Best,
