The invention provides a virtual reality operating system for robot live-working. The virtual reality operating system for robot live-working comprises a virtual reality system and an actual operatingsystem. According to the virtual reality operating system for robot live-working, robot live-working is combined with the virtual reality technology, an operator mainly undertakes the task of operating a virtual reality software, remotely operates a robot or enables the robot to operate autonomously, the virtual reality system obtains feedback information and establishes a virtual three-dimensional scene, the operator establishes a preliminary operation flow by analyzing a realistic virtual three-dimensional scene, then performs simulation operation through a simulation system to avoid misoperation, under the condition that the simulation operation is correct, the operator can remotely control the robot through a teleoperation system, or issue autonomous operation instructions to enable the robot to finish the operation process autonomously. During the operation process, the system continuously carries out modeling, rendering and three-dimensional reconstruction to ensure the real-time and operability of the system.
