One of the frustrations is the lack of standardization of drone EXIF tags (as well as sensor diameter meaning etc). Will need to check live on your drone. | |
Aug 19, 2022 at 22:56 | comment | added | Khaled | @Houska could you please explain why did you choose FlightYawAngle from EXIF and not GimbalYawAngle. My understaining: the camera is mounted on gimbal and the gimbal yaw angle is independant from drone itself, it is positive angle clockwise varying from -180 to 180 degrees from North but which North, magnetic or geographic like the one used on maps, no idea. | |

Explain what I meant

Aug 19, 2021 at 14:38 | comment | added | Houska | I thought about it briefly, but ran out of steam/interest before thinking too much. Adjusting for terrain via a single point, whether the drone position or an approximation of the centre of the image, shouldn't be too hard. Reflecting the differences in the DEM across the image, e.g. if one corner is higher than another, would be a hassle. | |
