Collaborative virtual and actual sheltering treatment method in shared enhanced real scene

Abstract

The invention discloses a collaborative virtual and actual sheltering treatment method in a shared enhanced real scene. The collaborative virtual and actual sheltering treatment method comprises the following steps of: generating an enhanced real scene; estimating the position of a point to be observed; projecting both a virtual object and a real object on an observation plane of the point to be observed, wherein the sheltering relationship between the virtual object and the real object is to be analyzed; taking the point to be observed as an initial point; taking a ray vertical to an imaging plane to scan the observation plane along the horizontal direction; carrying out sheltering encoding according to a successive sequence that the ray touches two sides of the virtual object and two sides of the real object when the ray scans the observation plane; determining whether the virtual object and the real object which are observed from the point to be observed are in either a sheltering relationship or a non-sheltering relationship according to the difference among sheltering codes; and specifically judging that the virtual object shelters the real object or the real object shelters the virtual object so as to reduce wrong judgment. According to the collaborative virtual and actual sheltering treatment method in the shared enhanced real scene, the quick judgment of the spatial sheltering relationship between the virtual object and the real object in a new video sequence region is achieved, and the accuracy in the judgment of the virtual and actual sheltering relationship in the enhanced real scene is improved.

Description

technical field [0001] The invention relates to the fields of virtual reality, augmented reality and computer graphics, in particular to a method for collaborative virtual-real occlusion processing in a shared augmented reality scene. Background technique [0002] The virtual and real occlusion processing of the augmented reality scene mainly refers to: judging and processing the possible occlusion or covering phenomenon between the virtual object and the real object according to the mutual spatial position information of the virtual object and the real object in the augmented reality scene. The spatial occlusion relationship between virtual objects and real objects not only directly affects the degree of virtual-real fusion between the virtual environment and the real environment, but also affects the visual fidelity generated by the augmented reality scene, and can affect the user's perception of spatial orientation and perception in the augmented reality scene. spatial in...

AI Technical Summary

Problems solved by technology

Since a single video sequence can only describe the real environment in a certain direction and range, it is difficult for the augmented reality scene based on a single video sequence to meet the scene perception and interactive operation in different directions, so it is necessary to use multiple video sequences to represent the multiplicity of the augmented reality scene. azimuth real environment

Using the main virtual and real occlusion processing methods of the current research status at home and abroad, the problem is that the real scene depth information of all video sequences must be calculated. When the number of video sequences describing the real environment is increasing, this requires the augmented reality system to have a strong Computing power, and may greatly reduce the real-time performance of the system and the timeliness of the user's work, thus restricting the generation effect and application promotion of augmented reality scenes
