Abstract

The invention provides a recording and playback method and a device of a virtual surgical simulation process. The method comprises the steps: event pre-classification: obtaining a plurality of operation signals in different surgery types, abstracting each operation signal into a response event, mapping the response events into an integer set comprising a plurality of integer identifications, and corresponding the response events to the integer identifications one to one; recording: storing an initial scene state, sequentially obtaining the operation signals of the current surgery type, inquiring and storing the integer identifications corresponding to the operation signals of the current surgery type respectively according to the obtained operation signals at the same time, and generating a recording segment according to the stored integer identifications and the initial scene state; and playback: obtaining the initial scene state, sequentially obtaining the integer identification in the recording segment according to a storage sequence, and responding and rendering according to the obtained integer identifications and the initial scene state at the same time to generate and display a new scene state.

Description

technical field [0001] The present invention relates to a virtual surgery data processing technology, in particular to a method and device for recording and replaying a virtual surgery simulation process. Background technique [0002] Virtual surgery is a technology that uses medical imaging data and uses virtual reality technology to create a virtual environment in the computer, enabling doctors to use the information in the virtual environment to plan, train, and guide surgery in actual operations. The use of virtual reality technology to virtualize the surgical environment can immerse medical workers in the virtual scene, perceive and learn various surgical operations through sight, hearing, and touch, and experience and learn how to deal with the actual situation in clinical operations. This saves the cost and time of training medical personnel, greatly reduces the risk of unskilled personnel performing operations, and has special significance for improving the efficienc...
