I've found a number of how-tos for solving video but I'm just looking to put an element in a photo and can't seem to find a how-to for that. Is it possible in blender to do a camera solve with a still image? Thanks.

  • $\begingroup$ I don't think I get what you are asking . . . there isn't any parallax or rate of change ratios that can be compared to a constant like that. You shouldn't need it $\endgroup$

  • $\begingroup$ In cinema 4d they have a camera calibrator tag where you can load an image for the camera and then draw lines that represent the x, y and z axis. once you have a few lines drawn for each axis that follows lines in the photo you can select 2 lines and use them as a pin which means the world origin. Once all of that is done, c4d can solve the camera. It's all based on a single image, not a video. I'm just wondering if you can do the same in blender. Here's a video of it in c4d - youtube.com/watch?v=CIt6jKXEITc $\endgroup$ Jul 8, 2015 at 18:41

    $\begingroup$ not using the tracker, but there is a great (free) addon that will help you here (sounds like it works the same as cinema 4d). $\endgroup$

    $\begingroup$ @David your recommendation is awesome, this should be an answer. (including the github link github.com/stuffmatic/blam ) $\endgroup$

There is an addon called BLAM: Camera Calibration Toolkit it can be used to match geometry to still images.

It uses the grease pencil to determine the perspective and focal length, and has tools for geometry reconstruction.

see http://stuffmatic.com/blam-blender-camera-calibration-toolkit/ It can be downloaded here: http://stuffmatic.github.io/

UPDATE: Blam is no longer mantained and has been replaced by fspy:

https://fspy.io/

For a detailed post on how to use blam and Fspy read: How can I recreate geometry using a photograph?
