Problems solved by technology

However, due to the limitations of the current 3D modeling, the realism of this method is still relatively lacking. At the same time, due to the large amount of data and high requirements for real-time processing, it also poses a huge test to the performance of the computer.

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0027] 1. Stitching of panoramas

[0028] Panoramic image stitching refers to a scene rendering method that uses partially overlapping image samples obtained by camera translation or rotation to generate a larger or even 360-degree omnidirectional image. That is, a set of partial images of a real scene is given, and then this set of images is stitched to generate a new view containing this set of partial images. figure 1 It is the basic process of image stitching.

[0029] At present, panoramas can be basically divided into cylindrical, spherical, and cubic forms. Spherical panoramas have the best effect and are most suitable for visual conversion of camera parameter models and are widely used. The stitching of panorama generally has the following ste...

Abstract

The invention discloses a panorama-based panoramic virtual tour method. The method comprises the following steps of: splicing and generating a panorama on the basis of image characteristic detection technology and low-noise image fusion technology; removing black edges from the panorama; and implementing an algorithm of an efficient panorama browser and the like. In the steps of characteristic detection, characteristic matching, mismatch removal, parameter optimization, image fusion and the like of panorama splicing technology, algorithms, such as scale invariant feature transform (SIFT), random sample consensus (RANSAC), k-d tree, Bundle Adjustment and the like are improved and applied to achieve a high processing speed and a vivid virtual tour effect. The method has a high practical value.

Description

technical field [0001] The invention belongs to the field of virtual reality, and in particular relates to stitching and browsing panoramas using image processing technology. Background technique [0002] Through the Internet or other carriers, the tourist landscape is dynamically and realistically presented in front of tourists, allowing tourists to choose the tour route, speed and viewpoint according to their own wishes, and to visit the beautiful scenery thousands of miles away without leaving home. This is virtual tour. As an important way to realize the virtual tourism experience, the 3D engine is mainly used to create a virtual tourism environment on the computer. Through the interactive experience with the virtual environment, people can enter a virtual tourist attraction on a personal computer and browse in real time in the virtual landscape. [0003] At present, there are two main methods of virtual tour using computer vision technology: [0004] 1. A virtual tou...
