New ALS boresight calibration method removes scene requirements

Researchers have developed a new method for boresight calibration of airborne laser scanning (ALS) systems that removes the need for specific scene content. This scene-agnostic approach utilizes point-to-point correspondences extracted from overlapping ALS strips, offering a more flexible and widely applicable solution compared to traditional plane-based methods. The proposed formulations, evaluated across various flight conditions and inertial systems, demonstrate the ability to recover or absorb boresight effects under standard mapping geometries, suggesting that calibration can be performed during routine mapping operations without special scene prerequisites.
