With the continuous development of virtual reality technology and the arrival of 5G era, computer technology offers users more practical and immersive medical services. And due to the impact of COVID-19, online medical services are becoming more and more popular. This paper completes the production of virtual scenes and character models with the help of Unity3D platform and 3DSMAX modeling software. And combined with speech recognition and speech synthesis services provided by Baidu AI and OLAMI artificial intelligence platform, the virtual intelligent doctor consultation system is achieved. Taking the COVID-19 epidemic as an example, this system allows users to communicate with virtual doctors and complete the entire consultation process by simulating the form of question and answer between patients and doctors in real life. The test results show that the virtual intelligent doctor consultation system designed and developed in this paper has certain interest and practicability in the medical consultation application scenario.
Nowadays, with the growing maturity of action capture technology and the increasing requirements of the game and film industry for action and shooting level, action capture technology has become more and more widely applied. In addition, virtual shooting is widely applied to many TV programs and film production. For example, the movie “The Lion King” released in 2019 was completed using virtual shooting technology. For example, the orangutan king Caesar in the movie “Rise of the Planet of the Apes” was completed by actor Andy Serkis through motion capture and expression capture. In the process of research and use, the synchronization of virtual camera motion attitude has been difficult to solve, and its accuracy needs to be improved. Furthermore, either the traditional single optical motion capture or the inertial motion capture can better tackle the multiplayer motion capture. In order to solve this problem, based on the Unity3D platform, the position of camera and virtual role is accurately located by optical positioning technology, and then inertial attitude sensing technology is used to obtain the attitude of multiple targets, achieving the integration of the optical positioning and the inertial attitude sensor. As a result, the real-time virtual shooting of multiplayer motion capture can be realized.
