my question is related to the motion tracking feature in Blender. I have successfully applied this feature to track the movement of a series of markers in a column during an Earthquake, based on a series of photos and a fixed camera.

I am wondering if is it possible to track 3D displacements of markers as a function of time. Basically from a series of photos from a fixed point, taken at regular intervals is it possible for 3D surfaces ?. For instance it would be interesting to monitor the deformations of a slope or mass of soil based on a series of marker, but in this case it is a 3D problem.

Thank you.

  • $\begingroup$ The tracker works by matching distinct features in an image, To reconstruc 3D motion, the tracking process needs some form of parallax, where the camera or the object are seen from different angles, else the tracking can only determine motion in 2d, and will only give you information on the movement of the pixels within the image. $\endgroup$ – cegaton Nov 20 at 0:02
