Hi all,
I am trying to work with a video that was shot by a Canon Powershot G16. By taking ~3 frames per second, I am able to build a decent looking model from this video, showing the bumps in the terrain properly. I want to make sure calibration parameters are included as well, but as soon as I enter what I think are the right parameters, the model becomes 2D planar.
According to the specs, the pixel size of this camera is 7.44 mm x 5.58 mm.
It's a compact camera, which has 5x optical zoom focal length from 6.1-30.5mm. The 35mm equivalent of this range is 28–140mm.
According to the metadata of my video, the focal length I shot was 6.1mm.
Both 7.44 mm x 5.58 mm & 6.1mm and 7.44 mm x 5.58 mm & 28 mm result in a planar model. In both cases, I entered the "camera type" to be Frame.
Can someone advice what the right combination of parameters should be?
Many thanks.
