How to create a 2D room map with multiple frames of an image / film?

Question

I would like to create a simple 2D map of the room, taking pictures (ceiling) in all directions (360 ° - for example, motion pictures), recognize the walls by detecting the edges, delete other unwanted objects, compare the images to the correct position (see walls, panorama) and finally, create an approximate two-dimensional map (looking at it from above). Obtaining a scale will be another parameter that may be useful.

I have my own ideas at the moment, using, for example, the Sobel algorithm, but it would be interesting if someone out there knows some kind of project or software (GPL, freeware prefered), doing this already, since I'm still I am looking for some examples that can help me.

Thank.

Answer 1

There are two ways to see how this works (kinda):

1) Determine the distance between the wall and the point at which the photograph was taken. A simple, consistent way to do this would be to use a laser or similar external measuring device. If you had to rely only on the device, you would need to consider the height of the person taking the photo, the camera angle and, of course, the characteristics of the lens of the device itself (for example, focal length distortion).
