JavaCV and OpenCV Camera Calibration with sample code

[jviolette123]

We are using Axis 1011.

Check out these images for comparison. One is the original, the other is after the correction. Look at the edges to see how many pixels off the edges are. When the image is up close, errors are insignificant (more pixels to get the distance). As the robot moves away from the hoops, the rectangle gets smaller in the frame, and moves towards the edges.

Check out this radial shot and measure the pixels per cm between rings 1-2 and the pixels per cm between rings 7-8.
