Camera Pose Estimation Based on Balls in Image
Hi,
I just stumbled across OpenCV and would like to know if it might help with my problem.
I look for a way to have a photo like the attached as an input and which outputs me world space camera coordinates and rotation. This data will be used to put the camera into a 3d program to render a 3d object onto the image.
The green markers I draw in the image will later be colored balls or other objects that will be placed in a perfect square of a known size which should help the solving.
Do you think this will be possible? Will a calibration photo also be needed?
Just need some pointers what to search for as I have no experience with this topic.
Thanks Andreas
Do you have to use the green balls? An easier (an more accurate way) would be to create a huge marker (1mx1m) and find that. This is much easier implement but it covers of course a larger part of the image. But it looks as if you want to place a car in the image, so maybe the object is large enough to cover the marker. (Or you take one shot with marker and one without with a static camera).
