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 ...

Abstract

Systems and methods for registration of image pairs, including camera response function normalization are disclosed and include selecting a pair of images from a set of images, each of the pair of images having associated metadata, determining a camera response function for each of the images in the pair of images using the associated metadata, normalizing each camera response function for across the set of images, and applying the normalized camera response function to the pair of images. A deformation map is generated in a multi-scale process using registration parameters, to deform one of the pair of images to align with another of the pair of images. The image pairs may be selected by identifying image pairs having an overlap that exceeds an overlap threshold, having a sequential proximity in an image series satisfying a proximity threshold, and/or having estimated image capture attitudes within an attitude threshold.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority and benefit to U.S. Provisional Patent Application No. 62 / 756,522, filed November 6, 2018 and entitled "RESPONSE NORMALIZATION FOROVERLAPPED MULTI-IMAGE APPLICATIONS," which is hereby incorporated by reference in its entirety. technical field [0003] One or more embodiments of the present disclosure relate generally to imaging systems, and more specifically, for example, to systems and methods for combining two or more overlapping images into a data set. Background technique [0004] In the field of image processing, there is a continuing need for efficient and reliable ways to analyze and process images captured by imaging devices. Some systems include one or more image sensors and / or cameras to capture images of one or more fields of view (eg, images of a scene). In one approach, multiple captured images are aligned and / or stitched together by identifying points in one image ...
