Very well explanation, thanks for the video.

I recently used LM to tighten up skew lines to find the 3D location of a set of cameras in relation to a source, thus knowing the 3D locations of the source points. Of course the system was not scaled, I just used best guess. I was only really interested in the shape.

Thanks for your educative videos especially on photogrammetry. I want to ask if its possible to use phone camera to reconstruct a 3D model of a building? Please, do suggest any way I can approach the study of possible. Thanks.

There are unknown way to visualize subspace, or vector spaces.

You can stretching the width of the x axis, for example, in the right line of a 3d stereo image, and also get depth, as shown below.

TIP: To get the 3d depth, close one eye and focus on either left or right line, and then open it.


This because the z axis uses x to get depth. Which means that you can get double depth to the image.... 4d depth??? :O

Thanks for good explanation cyrill
I always watch your videos
I have a question
I want to find out about the universities which offers photogrammetry for phd but I have no idea how to find out about it
May you give me a clue?!
