Example Embodiment

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] In existing Web AR applications, the real-world part opens the image acquisition device of the mobile device through the WebRTC protocol, but the real-world part is acquired through WebRTC, and there are a lot of redundant operations in the process, which is easy to cause the real-world part and the virtual world part to be rendered. Ou...

Abstract

The embodiment of the invention provides a Web augmented reality rendering method and device. The method comprises the stepsthe following steps of sending a native calling instruction to a terminal, so that the terminal can control real image acquisition equipment to acquire a real world image based on the native calling instruction, the real world image is rendered to a Web window, and returningposition and posture information of the real image acquisition equipment; rendering the virtual world image to a Web window based on the position and attitude information of the real image acquisitiondevice. The embodiment of the invention provides a method and device. A real image acquisition device is controlled by a calling terminal to acquire a real world image; Compared with a method for rendering the real world part through WebRTC, the method has the advantages that the operation process can be effectively simplified, redundant operation can be avoided, the rendering efficiency of the real world image can be improved, the problem that the real world part and the virtual world part are not synchronous in the rendering process can be solved, and the user experience can be optimized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of augmented reality, and in particular, to a method and device for rendering Web augmented reality. Background technique [0002] The rapid progress of mobile Internet technology has not only changed the way of life of human beings, but also promoted the vigorous development of augmented reality (Augmented Reality, AR) applications. Compared with the disadvantages of closedness, high cross-platform cost, and difficulty in dissemination of native AR applications on mobile terminals, AR applications based on Web (Global Wide Area Network) browsers (hereinafter referred to as Web AR applications) are versatile and have good cross-platform characteristics. And easy to spread, using the web browser as the carrier of AR applications can effectively solve the problems existing in native AR applications. However, there is a big gap between Web AR applications and native AR applications in...
