Abstract

The invention discloses a method for real-time masking in a full virtual environment based on AR imaging, and relates to the field of AR; in order to achieve the purpose, the technical scheme of the invention comprises the following steps: on the basis of completing three-dimensional digital model art processing, making a MASK masking model of a corresponding model, and writing a calling logic of the masking model; when the MASK mask model is called, cutting the image of the virtual model out; in the software, binding and matching related props created in the motion capture software and a rigid body of a simulation person with corresponding models and skeletons; accessing motion capture data into the software and wirelessly transmitting to the AR glasses in real time. The problem that traditional first-aid training cannot reflect the actual environment of disaster on-site treatment and the on-site psychological feeling of the trainee is solved.

Description

technical field [0001] The invention relates to a method for real-time masking in a full virtual environment based on AR imaging, and mainly relates to the field of AR. Background technique [0002] In order to improve the training quality of disaster medical rescue talents, it is necessary to build a virtual simulation practice teaching platform with "disaster environment and modern warfare". Virtual reality technology is a multidisciplinary integration of computer graphics, medical image processing, visualization technology, software engineering, human-machine interface technology, sensing and measurement technology, simulation technology, pattern recognition, artificial intelligence, distributed real-time processing technology, network technology, etc. crystallization. At present, there is no virtual simulation disaster environment simulation platform in China. Contents of the invention [0003] Aiming at the deficiencies of the above existing technologies, the invent...
