Problems solved by technology

[0003] However, there are many problems in the application of the existing virtual reality large space solutions. The cost of multiple cameras erected above the site is high, and it is difficult to debug and maintain.
In addition, when the number of users in the scene is too dense, some actions will be blocked by other users. Since this action cannot be captured and recognized, it will cause the lack of corresponding actions in the virtual reality scene, affecting the user's virtual reality interaction experience.

Abstract

The invention discloses a computer vision large-space positioning method and a system based on SLAM. The method comprises the steps that a shooting module shoots a scene image in a user visual field range, an inertia measurement module detects user posture information; a transmission module transmits the scene image and the user posture information to the server side; an image preprocessing moduleprocesses to obtain scene coordinate information and a user trunk posture; an SLAM module constructs an instant map according to the scene coordinate information and the user posture information, a content generation module generates a user virtual model in the instant map to obtain a virtual reality large-space scene, and the transmission module transmits the virtual reality large-space scene tothe display module for display. Visibly, a camera installed on the user terminal enables the cost of the virtual reality large-space scheme to be remarkably reduced, the shooting view angles of multiple users in different directions in the large space are integrated, the action posture of each user is completely and clearly recognized, and the virtual reality interaction experience of the users is good.

Description

technical field [0001] The invention relates to the technical field of spatial positioning, in particular to a large-space positioning method and system based on SLAM for computer vision. Background technique [0002] Virtual reality large space technology refers to the use of wireless transmission, machine vision, spatial positioning and other technologies to realize real-time virtual reality interaction of multiple people in a wide scene. It can be seen that virtual reality large space technology is very suitable for online applications. Application scenarios such as multi-person VR battles, large space experience halls, virtual reality intelligent classrooms and virtual playgrounds. [0003] However, the existing large-scale virtual reality solutions have many problems in application. The multiple cameras installed above the venue are expensive and difficult to debug and maintain. In addition, when the number of users in the scene is too dense, some actions will be block...
