Abstract

The invention discloses a combined interactive base map updating method and device, and the method comprises the following steps: carrying out the coarse registration and fine registration of a panoramic base map and an updated image, obtaining a matching point, and calculating a total transformation parameter according to the matching point; acquiring an overlapped image between the panoramic base map and the updated image according to the total transformation parameter; obtaining an invariant region set between the overlapped image and the updated image; determining a color correction parameter according to the invariant region set, and performing color correction on the updated image based on the color correction parameter; and carrying out linear weighted fusion on the edge of the updated image after color correction and the edge of the overlapped image, and splicing the fused image to the panoramic base map to obtain an updated panoramic base map. The method can improve the accuracy of resolution, scale and content registration between the panoramic base map and the updated image by performing coarse and fine registration on the image, corrects the image by using correction parameters, reduces the color difference between the images, and can obtain the panoramic base map with an ideal color correction effect.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an interactive base map update method and device. Background technique [0002] In the panoramic video monitoring system, multi-channel network monitoring video data is converted into visualized panoramic monitoring video data, and the spatial transformation relationship between the field of view of each camera and the panoramic base map is calculated to calibrate it to the panoramic map. The camera's real-time video data is embedded in the static panoramic base map, which realizes the fusion and preview of the panoramic monitoring video data, which greatly facilitates the monitoring personnel to observe the spatial position relationship of each camera. [0003] In the actual scene, some areas may change over time, and there is a big difference between the panorama basemap. The left side is the panorama basemap to be updated, the changed area is in the box, and the The co...
