Abstract

The article is devoted to the problem of creating panoramas in conditions of differences in the color palette and illumination level of stitched images caused both by the features of the optical system and by the weather and other factors. A procedure for correcting brightness and color is proposed to minimize differences between stitched images and to reduce negative impacts.
The features of detection of key points by various methods during the stitching of panoramic images under conditions of shooting at different heights are presented.
The effect of an additional procedure for correcting brightness and color on the number of found key points is described. The quality of the final panoramic images and the time of their stitching were evaluated. In the course of the work, statistical data were obtained and their comparative analysis was carried out.
