Hi community,
I’m experiencing a recurring issue when processing my images with Pix4Dmapper. After generating the orthomosaic and the DTM, I notice visible stripes along the flight lines (in the direction of the flight). These stripes affect the visual quality of the final product and also make it harder to carry out certain analyses based on the data.
In the DTM, the problem is even more critical:
there are noticeable elevation differences between the stripes, which creates an artificial pattern on an otherwise flat agricultural field.
Project details
- Drone: Ebee X
- Camera: Aeria X
- Frontal / lateral overlap: 75% / 75%
- Terrain type: Agricultural, very flat
- Software: Pix4Dmapper
- Flight time: 12:00 PM (stable lighting conditions)
I’ve tried adjusting parameters during the calibration step and DSM generation, but the issue remains.
Has anyone experienced this same effect?
Do you have any recommendations on how to avoid or correct these stripes, both in the orthomosaic and especially in the DTM?
I suspect this might be related to soil reflectance affecting the camera sensor. Has anyone found a way to mitigate this?
Maybe some kind of image calibration or preprocessing?
Thanks in advance for any help!
