AI Technical Summary

Problems solved by technology

[0004] However, the direct stitching method requires complex initialization operations, such as camera calibration
Although the feature-based method does not require initialization, it causes problems such as lack of invariance when processing double fisheye images.

Abstract

The present invention provides an image generation method, device and system. The method includes: obtaining an initial panoramic image corresponding to a first pair of fish-eye images; extracting a first characteristic image from the initial panoramic image; and extracting a first characteristic image from the second pair of fish-eye images. Extract visual feature information; wherein, the resolution of the second Pisces image is higher than the resolution of the first Pisces image; the first feature image and the visual feature information are fused to obtain a fused panoramic image . It can achieve high-precision, high-resolution fused panoramic images without requiring high-demand hardware equipment or cumbersome operations such as initialization. It can also increase the speed of obtaining high-resolution fused panoramic images.

Description

technical field [0001] The present invention relates to the technical field of computer image processing, in particular to an image generation method, device and system. Background technique [0002] With the development of omnidirectional cameras, 360-degree panoramic images have attracted much attention in recent years, and 360-degree panoramic image generation technology is widely used in biology, medicine, modeling and virtual reality and other fields. A 360-degree panoramic image is also referred to as a three-dimensional panoramic image or a panoramic surround view image. The 360-degree panoramic image generation technology is a three-dimensional virtual display technology that uses a digital camera to look around the existing scene from multiple angles, then uses a computer for post-stitching, and completes it by loading a playback program. [0003] The methods for generating 360-degree panoramic images in the prior art are mainly divided into two types, direct stitc...
