Calibration Method for Aerial Vehicles
Utah State University
Aerial vehicles make good remote sensing platforms by reducing the cost and making imagery easier to obtain. The low altitude, small image footprint and high number of images make it difficult and tedious to georeference the images based on features. Auto-orthorectification techniques based on the position and attitude of the aerial vehicle would work well except the inherent errors in the aerial vehicle sensors reduce the accuracy of the orthorectification significantly. The orthorectification accuracy is improved by calibrating the aerial vehicle sensors. This is done by inverse orthorectifing the images to find the actual position and attitude of the aerial vehicle using ground references setup in a square.
