How does solvePnP (iterative) initialize its solution

asked 2015-07-28 18:58:10 -0600

Documentation says that solvePnP uses iterative method by default. However iterative method needs an initial solution to work and it does not say how the solution is initialized. I would like to know this for my thesis.

Is it maybe a simple DLT (the one that needs at least 6 points) or something else?

OpenCV is OpenSource so let's check:

SolvePnP is here: github and it uses cvFindExtrinsicCameraParams2 if the Iterative-Flag is set. And that function is here.

So at least the comment says that it uses the DLT if you have a non-planar set of points.
