Does OpenCV support the ability to calculate lens distortion coefficients using a series of images which has just lines? I want to use lines because I am using a laser triangulated 3D measurement technique for finding range information. Attempted to use standard chess board however the results are less than desired. The images with lines represent captured single frame images of a fixture which a sheet of light laser strikes. The fixture is known to be precision machined and flat. Obviously, when seen by the camera, the line appears curved do to the lens distortion.

How can I perform this task using OpenCV calibrateCamera? Can I just walk along the imagine curve and pick points using a fixed step distance between points? Also, the points are calculated from a cog method.

I would attach an image to illustrate the line but I don't know how to attach imagines in this forum.

Thanks,

James

I am attaching a few imagines to illustrate.

Of course there are many more imagines that would attach an image to illustrate the line but I don't be use that the two I have attached. But the idea is that these lines are captured in the laser plane on a know how to attach imagines in this forum.flat surface. I would like to use these to perform the lens distortion calibration.
