colmap #60

Thank you for your work. Why is the camera posture obtained by using colmap on the monocular video so far from the camera posture obtained by ARkit? You said that colmap cannot recover the metric scale of the camera's posture. How do we get the metric scale? How does the metric scale behave in ARkit?

You can try to use evo to recover the scale of the poses from COLMAP. Poses from ARKit are usually quite accurate and reliable.

Thank you for your reply. After consulting evo related materials, I found that the automatic calibration scale in evo requires a standard set to be calibrated, and now I only have the camera attitude data recovered from colmap, how do I obtain this standard?

ARKit can be used to obtain poses with metric scale.
