I run a test project made up of several different flights. One of them resulted in darker images. However, pix4dMapper resolved the model with accuracy and the large difference in picture exposition did not affect the DSM or orthomosaic accuracy. Some of the areas of the underexposed flight, though, appear too dark in the orthomosaic. I want to edit those particular pictures (wih XnView or Lightroom) and load them to the project. As image name and pixel location would be the same…there should be no problem to recompute DSM colour and orthomosaic using the calibration and DSM information from the previous project processing.
Does someone know if that is even possible?
