An aerial camera boresight calibration system

A boresight calibration system for calibrating line of sight data of an imaging system disposed on an aircraft, the line of sight data indicative of a line of sight determined during use for an image captured by the imaging system, the boresight calibration system arranged to:

• calculate boresight calibration parameters for images captured by the imaging system disposed on the aircraft using:
• line of sight data associated with first images of an existing bundle adjustment solution captured in a first aerial survey;
• and
• at least one image capture parameter associated with the first images, the at least one image capture parameter indicative of respective positions of at least one movable image capture component of the imaging system when the first images are captured in the first aerial survey, the at least one moveable image capture component movable relative to the aircraft;
• and
• apply the boresight calibration parameters to line of sight data associated with second images captured in a second aerial survey that have not been bundle adjusted, the boresight calibration parameters applied according to the respective positions of the at least one movable image capture component of the imaging system when the second images are captured in the second aerial survey.
