Particular camera setup and calibration process with opencv -

-

this first post , delighted part of community.

i've 2 webcams , want use detect 2d coordinates of center of white tennis balls. , find 3d coordinate of centers. cameras setup this. there's circular region of radius 7 feet , cameras placed on opposite end of each other means if camera1 placed @ 0 degree of circular region camera2 placed @ 180 degree of same region on straight line opposite of each other on circumference of circular region.

i need calibrate cameras , need find intrinsic , extrinsic parameters.i'm using opencv this.

can use cvstereocalibrate() camera setup?

i'm asking because if @ camera setup see there's point on camera1 , camera2's captured image collinear epipoles of both cameras. epipolar line point. issue calibration procedure? if yes possible tell me how solve problem?

this camera setup stereo cameras toed-in (really cross-eyed :). calibrate need correspondence points each image. can find these around edges ... way around in peripheral vision of each camera , think mirrored algorithm expect (have think one). have not tried this, think warp image doughnut assuming didn't confuse algorithm beyond recognition. stereo correspondence algorithms have problems this, think, because far in 1 near in other.
