Extrinsic Calibration of UAV and Multi RGB-D Cameras with Non-overlapping by using an External Camera

This paper presents a novel extrinsic calibration approach for rigid RGB-D cameras with non-overlapping view and UAV, which enables the tracking mission and autonomous flight to support the pilots during the control operation. The checkerboards with QR-marker are used as calibration patterns. Furthermore, a QR code attached on the top of UAV is used to define the UAV reference coordinate system. B...
