Camera Calibration and Augmented Reality
OpenCV camera calibration from chessboard and circle grids, with reprojection-error analysis and a 3D car drawn over a live webcam.
Team project.
What was built
We calibrated cameras with OpenCV from chessboard and circle-grid photos, measured how the reprojection error changes with the number of images, and compared two webcams and a mobile-device camera. The result goes to solvePnPRansac and projectPoints to draw a moving car on the live image.
