Calibration of cameras and scanners on UAV and mobile platforms

Boresight and lever arm calibration of cameras and scanners on UAVs or mobile platforms is performed by optimizing the flight/travel path of the UAV/platform relative to control points or tie points. The flight/travel paths account for the potential bias of boresight angles, lever arm and times delays to produce an accurate estimation of the orientation of these cameras/scanners relative to the GNSS/INS coordinate system of the UAV/platform.

Method of processing an image

A non-transitory computer-readable medium encoded with a computer-readable program, which when executed by a processor, will cause a computer to execute a computational method, the computational method including collecting an image data, wherein the collecting the image data comprises collecting a first plurality of RGB images and a second plurality of hyperspectral images. The method further includes orthorectifying the image data to produce an RGB based orthophoto and a partially rectified hyperspectral orthophoto. The method further includes selecting tie features from each of the RGB based orthophoto and the partially rectified hyperspectral orthophoto. Lastly, the method includes registering the features of the partially rectified hyperspectral orthophoto into the tie features of the RGB based orthophoto.
