I have been experimenting with reality capture for some SfM workflows and have thus far been quite happy with the performance of the system. However, one area where I have been unsuccessful so far is in adding in a prior about my camera systems pose. I am using a custom imaging system, such that pose is not added automatically to the EXIF of the images, so I am adding it after the fact.
I have established that I am able to pass pose information to Reality Capture (RC) using EXIF tags commonly associated with drones (Gimbal Pitch/Yaw/Roll), as that changes the pose prior which shows up in the RC view pane. I suspect that there is a transformation occurring when moving between my specified pose prior to RC's orientation co-ordinate system, however thus far have been unable to pin down exactly what that is. This is important as it seems my pose prior isn't being transformed properly in some fundamental ways (i.e. camera is pointing away from the ground plane when it should be facing towards it).
Any assistance in understanding how prior pose is being transformed (i.e. what if any assumptions are made, should I be using a different EXIF tag?) and any pre-processing I can do before feeding in my prior to make it play nice with RC would be greatly appreciated.
