Abstract

The embodiment of the invention discloses a panoramic image correction method and system. According to the panoramic image correction method and system, parameters of two fisheye lenses on a panoramiccamera and image coordinate values of all pixel points in two fisheye images shot by the two fisheye lenses are obtained; according to the parameters of the two fisheye lenses and the image coordinate values of all the pixel points in the two fisheye images, a camera coordinate value corresponding to each pixel point is obtained, and the camera coordinate values are converted and undated to be world coordinate values in a preset world coordinate system; according to the updated camera coordinate value corresponding to each pixel point in the two fisheye images, correction data of the fisheyeimages shot by the two fisheye lenses are obtained. The image coordinate values of all the pixel points in the fisheye images shot by the panoramic camera in any time can be regenerated through the correction data, and thus when the two regenerated fisheye images are spliced into a panoramic image, the dislocation phenomenon of the spliced part is avoided.

Description

technical field [0001] The present invention relates to the technical field of panoramic images, in particular to a panoramic image correction method and system. Background technique [0002] A panoramic camera refers to a camera that can shoot a 360° panorama at one time. It allows users to have scenes that cannot be captured by traditional cameras in a new way. In addition to taking pictures, a panoramic camera can also be used for shooting dynamic images, also known as a panoramic camera. . The viewing angle range of existing camera lenses is less than 360°, therefore, a panoramic camera must be equipped with at least two camera lenses to capture panoramic images. Different from the traditional camera / smartphone’s method of rotating and shooting panoramic images, the panoramic camera can simultaneously capture images in the horizontal and vertical directions, and the multiple images obtained can be panorama stitched to generate a 360° panoramic image. [0003] At presen...
