Abstract

The invention relates to the technical field of image processing, and particularly relates to a method and a device for eliminating image feature mismatching for panoramic stitching. The method comprises steps: S101, more than two to-be-stitched panoramic division maps are acquired; S102, image denoising and histogram equalization are carried out on the panoramic division maps; S103, feature extraction is carried out on the panoramic division maps obtained in the S102; S104, rough feature matching is carried out on the panoramic division maps obtained in the S103; S105, median filtering is carried out on the panoramic division maps in the S104; and S106, a precise feature matching pair is acquired: through feature extraction, rough feature matching and then median filtering, the precise feature matching pair is acquired, the image feature mismatching is eliminated, and the stitching effects are enhanced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a panoramic stitching method and device for eliminating image feature mismatch. Background technique [0002] Today, with the rapid development of the monitoring system, the scale of the system is getting bigger and bigger, and there are more and more monitoring points. The staff have no time to take care of more and more monitoring images. With the continuous expansion of the monitoring range, it is necessary to monitor the entire bridge. , airports, a long stretch of highway or high-rise buildings for monitoring, the field of view of most cameras cannot reach such a large monitoring range, so the requirements for video surveillance with a large field of view are gradually increasing, and a high-end demand has gradually formed. As a solution, panoramic video stitching has also received more and more attention. Image feature matching is an important link in the process ...
