Abstract

The invention discloses a method and device for processing panoramic images. The method includes acquiring multi-channel fish-eye images, performing synchronous processing on the multi-channel fish-eye images, and performing dark level calibration on each synchronously processed fish-eye image. , so that the multi-channel fisheye images can obtain the same gray value reference; the image consistency processing is performed on the multi-channel fish-eye images with the same gray value reference to compensate the brightness difference of the fish-eye images; the multi-channel image after image consistency processing Distortion correction is performed on the fisheye image to obtain multi-channel fish-eye expansion images, and the multi-channel fish-eye expansion images are stitched into a panoramic image. This application performs image processing operations such as synchronization, dark level calibration, and image consistency processing on multi-channel fisheye images, so that panoramic images and panoramic videos with consistent overall brightness can be obtained after splicing and fusion, which greatly improves the quality of panoramic images and panoramic images. The image quality of the video.

Description

technical field [0001] The present application relates to image processing technology, in particular to a panoramic image processing method and device. Background technique [0002] With the rapid development of virtual reality and augmented reality technology, panoramic video and panoramic images are widely accepted because they can bring users a 360-degree omnidirectional and immersive viewing experience. [0003] In the existing panorama processing and mosaic technology, image processing, mosaic fusion, etc. are still to be performed after image acquisition, encoding and compression. Due to the influence of imaging conditions and other factors, the panoramic image obtained after image stitching usually has the problem of inconsistent overall brightness of the image, resulting in poor image display effect and poor user experience. Contents of the invention [0004] In order to solve the above technical problems, the present application provides a panoramic image process...
