Hello.

Does anyone knows if there is free software available for photogrammetry ? Do you have any experience on this ?

I have a little project and i want to create 3D models of some objects based on photos of them. The models must be very precise so "creating" them from scratch on Blender is not the first option.

Thanks for your time.

Wow

I did experiment this with Blender for a little object for printing it in 3d, but it was quite hard to do.

Here is a serie of videos of the method I used in Blender to do this.

But if you intend to do this with a serie of different photos you shot, this can be a nigthmare.

The problem will always be the distortion of the different pictures.

In the videos I linked, you'll see that all the pictures are not distorted because it is planned.

Blender or not Blender, the problem will always be the photos.

Ideally, make a plan that can turn on 180°, put your object on it and take pictures while you turn your object without moving your camera.

And think about how Matrix was done.

Thank you Supertramp

Another solution with colmap & meshlab (GPLV3)

But the way I thought how to take the picture wasn't very far from the video for using colmap.

And if you build a rotating plan for not the camera to move, this should make the work easier for your computer.
