Method and device for positioning virtual character in interactive system

Abstract

The invention relates to the technical field of AR, and provides a method and equipment for positioning a virtual character in an interactive system, and the method comprises the steps: extracting the semantic information of a real object and the distance between the real object and a rendering terminal from a collected environment image of a real scene, and transmitting the semantic information and the distance to a collection terminal; the acquisition terminal adjusts the initial position of the virtual character in the acquisition coordinate system according to the received semantic information of the real object and the distance between the acquisition terminal and the rendering terminal, and synchronizes the adjusted target position to the rendering coordinate system, so that the target position of the virtual character is displayed by the rendering terminal when the virtual object is displayed through a bidirectional feedback mechanism of the rendering terminal and the acquisition terminal. The virtual object can be accurately placed in the real scene, the sense of violation of fusion of a virtual character and the real scene is weakened to a certain extent, and the authenticity of virtual-real fusion is improved.

Description

technical field [0001] The present application relates to the technical field of Augmented Reality (AR), and in particular, to a method and device for locating virtual characters in an interactive system. Background technique [0002] AR technology is a technology that ingeniously integrates simulated virtual information with the real world. With the development of AR technology and computer vision and computer graphics technology, virtual characters are applied in 3D communication scenarios, so as to realize the real world experience. "Enhancement" to improve the interactive experience is gradually becoming a new way of socializing. [0003] At present, in the actual AR interaction scene, the positioning methods of virtual characters mainly include the following: 1) According to the design of the virtual space, the virtual characters are placed in a fixed position in the three-dimensional space; 2) The virtual characters and surrounding areas are strictly set in advance. T...

Problems solved by technology

However, because the virtual character reconstructed by the acquisition terminal is out of touch with the rendering terminal, the virtual character at the current position may not be accurately integrated with the real scene displayed by the rendering terminal and the objects in the real scene, which reduces the authenticity of virtual-real fusion and affects User's AR experience
