To use this target, before each flight take a photo using each camera of the entire open package with the targets facing straight up (though no shadows on the entire target area). Accurate and robust calibration targets are essential for metrology and photogrammetry purposes. A vision calibration target can be used in two-dimensional and three-dimensional vision systems. camera_calibration allows easy calibration of monocular or stereo cameras using a checkerboard calibration target. Find optical-zoom cameras and interchangeable camera lenses for every project. First, launch the calibration node along with rviz. or on paper.
