Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0034] Such as figure 1 , which shows a schematic diagram of an application environment involved in an image correction method provided by an embodiment of the present invention. When splicing the various images captured by the panorama shooting device to generate a panorama, misplaced areas are likely to appear at the splicing of the two images. Such as figure 1 , which shows a schematic diagram of a panorama, figure 1 The area where the middle road is located is misaligned, such as figure 1 Shown in the dotted box. In order to process the misaligned area in the panorama, an embodiment of the present invention provides an image correction method. certainly, figure 1 The subsequent embodiments are only described by taking the dis...

The invention discloses an image correction method and device and belongs to the geographical map technical field. The method comprises following steps: obtaining the material image and the first target image region to be corrected in the panorama image; cutting out the second target image region matching with the first target image region from the material image, deforming to obtain the third target image region; confirming the fourth target image region from the third target image region; processing the pixel value of each pixel point in the fourth target image region to obtain the fifth target image region; splicing the fifth target image region to the panorama image to obtain the corrected panorama image. The misplaced region in the panorama image can be repaired and the appreciation of the visual of the panorama image is raised by obtaining the first target image region having dislocation from the panorama image, cutting out the second target image region matching with the first target image region from the material image, deforming the second target image region, and splicing the processed region to the panorama image.
Description
technical field [0001] The invention relates to the technical field of maps, in particular to an image correction method and device. Background technique [0002] With the rapid development of map technology, more and more panoramas appear, and users can obtain 360-degree panoramas of cities, streets or other environments according to the panoramas. Among them, the panorama is formed by taking a 360-degree shot at a fixed point by an image shooting device, obtaining images from various angles, and splicing each image through a splicing algorithm. When stitching each image, there may be misalignment at the edges of the two images, causing the boundaries of the two images in the panorama to be misaligned. [0003] When the dislocation area appears in the road area, building area and other areas in the panorama, since these objects have a strong structure, the user will feel that the panorama is severely distorted and has poor visual appreciation. In order to avoid this situa...
