Camera Calibration
Defines the 3D to 2D mapping
Multiple cameras calibrated to a common world coordinate system.
Common world coordinates allows volumetric calibration
Use a Pinhole camera model plus radial distortion correction
Notes:
Camera Calibration defines the mapping between a 3D point in the world to a 2D point on the camera image.
Our system uses multiple cameras that are calibrated to a common world coordinate system.
Using common world coordinates allows us to calibrate the commonly observed volume, which is the 3D intersection of the views from all cameras.
This is a multi-camera volumetric calibration
