Embodiment Construction
[0019] The present disclosure provides improved systems and methods for aligning image pairs, including a novel end-to-end solution that addresses camera response function normalization. The solution disclosed herein allows for the co-operation of multiple images at once, and is particularly suitable for processing infrared images captured during unmanned aerial system (UAS) flights. Infrared images such as thermal images may respond differently depending on altitude, differences in environmental conditions during flight, heated image capture systems, flight angle, image parameters, and other factors. Image capture systems can be configured to compensate for these variations during image capture, but the resulting images are not always normalized.
[0020] In various implementations, the camera response function (CRF) normalization process includes an algorithm that applies offset and gain corrections to the captured images such that stitching artifacts will be minimized. In ...
