specific Embodiment 1

[0127] Such as Figure 13 , the specific embodiment of the present invention one is:

[0128] First construct the image pyramid hierarchical structure, decompose the input image into a series of bandpass layers of different frequency bands; then fuse each bandpass layer separately to obtain the bandpass layer of the stitched image: finally reconstruct the bandpass layer of the stitched image to obtain The final stitched image. Because the image fusion is carried out in different frequency bands, it can effectively avoid the ghosting of the image fusion; and because the multi-band decomposition and reconstruction of the image is a reciprocal process, using this method can ensure the correctness of the resulting spliced ​​image. Specific steps are as follows:

[0129] Step1: Construct the hierarchical structure of the image pyramid, and obtain the Gaussian pyramid G0 of each image and the decomposed Gl, G2, ..., GN;

[0130] Where G0 is the original image, w(m, n)=h(m)h(n) ...

Abstract

The invention relates to the technical field of image processing, in particular to a method and device for smoothing seams of panoramic stitching images. By decomposing each panoramic partition image into multi-layer frequency bands, the fusion of images is carried out separately in different frequency bands, which can effectively avoid ghost images during image fusion, and achieve smoothness at the seams of panoramic stitching images, and due to the multi-layer frequency bands of images Decomposition and reconstruction are a reciprocal process, and using this method can guarantee the correctness of the resulting stitched image. The generation of panoramas meets the requirements of video surveillance with a large field of view. With the continuous expansion of the monitoring range, it is necessary to monitor the entire bridge, airport, a long section of road or high-rise buildings. The field of view of most cameras cannot reach this A large monitoring range has gradually formed a high-end demand. Smoothing the seams of panorama stitched images can make the panorama look smoother.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for smoothing seams of panoramic stitching images. 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. The joints of panorama stitching often cannot be spliced ​​smoothly....
