Implementation method of augmented reality technology for mobile terminal based on web

Abstract

The invention provides an implementation method of augmented reality technology for a mobile terminal based on a web. The method comprises: starting a first program to start a camera to collect a target object image in the real world; a third program obtaining a perspective projection coordinate of the target object on a screen of the mobile terminal device according to the pose of the camera; sending a model downloading request to a remote server by using a Web browser, the remote server carries out simplified model processing and compression processing on the AR model requested to be downloaded. The problem that a browser is downloaded too slowly due to the fact that an AR model file is too large is solved. A grid rectangle is added to the enhanced display information model subjected todecompression processing by the third program. The touch dragging distance is converted into an enhanced display information model position or angle and size variation. In the rendering part, ambientlight is used for weakening shadows or adding colors to the enhanced display information model, target model attributes are set to ensure that a light source is aligned with a set enhanced display information model object for irradiation, and the rendering truth of the enhanced display information model is improved.

Description

technical field [0001] The invention relates to a method for realizing the web-based augmented reality technology of a mobile terminal. Background technique [0002] With the development of the Internet and the convenience of communication, the number of people using mobile devices is increasing, and augmented reality, or AR technology, is emerging. The application of AR technology provides convenience to people in many fields. After the measurement of the size, take the data and go out to the furniture store to buy. After the furniture is purchased, you will know the specific effect of the furniture placed indoors. Many times, the furniture you buy is not suitable for the indoor decoration style and size information. Through the experience of the model through Web AR, you can feel the convenience brought by technology. You only need to know the placement effect of the furniture you want to buy at home, which saves time and is more environmentally friendly and economical. ...

AI Technical Summary

Problems solved by technology

There are some defects in the existing Web AR support. The enhanced display information model file is too large, resulting in slow downloading of the browser. In serious cases, the browser software will be stuck, and a mobile device with a higher configuration needs to be used for browsing. In addition, the model rendering The realism is not enough, the model lacks realism and the shadow effect does not reflect the realism of the model to a large extent. In addition, Web AR loads multiple models and cannot freely operate on a certain model object, such as: zoom in, rotate, move, etc.
