Hi @fitsalem and @hui,

Could you check if the camera parameter is the same as the one shared in this thread?

[DJI Zenmuse XT2: Calibrated camera (RGB and thermal 19mm)](https://community.pix4d.com/t/dji-zenmuse-xt2-calibrated-camera-rgb-and-thermal-19mm/8958)

Sometimes the pixel size is read incorrectly, and you need to enter the correct one.

Best,  
Rosana (she/her)
