Multi Camera Setups and Calibrations

Link Tree

The NxLib provides a number of functions that simplify the use of different coordinate systems. How they are created by different commands, how you can create your own coordinate systems and how you can influence the resulting coordinate system of your 3D data is discussed in the topic on Links, Coordinate Systems and LinkTree.

Multi Camera Setups

The NxLib provides functions for using multiple cameras together, so that all of their data is automatically lined up. This is discussed in the topic on multi camera setups. A special case of this is that you can use a monocular camera to texture the 3D data returned by a stereo camera. This is discussed in the topic on texturing point clouds.

Calibrations

The NxLib also provides ways in which you can change the coordinate system of the calculated 3D data. You can align your data with fixed points in the real world by performing a workspace calibration. When your camera should work together with a robot and you need to coordinate the robot’s movement with data from the camera, you can perform a hand-eye calibration.
