Abstract

The paper considers the question of stitching of infrared images obtained from different points and with the modified internal parameters of the camera. As test data, we use images taken by the thermal camera. To combine pairs of images, we use the several auxiliary algorithms are required, including: elimination of noise on images (denoising); restoration of sharpness on images (deblurring); search for basic elements on pairs IR images; separation of images into elements with given threshold values; search for correlations between base elements; elimination of false matches; search for the image conversion coefficient; search for the boundary of stitching and check the conditions for overlapping objects; if necessary, the perform the color correction operation and change the color balance; stitching pair of images and finding a common border. On the set of test images show the effectiveness of the proposed approach.
