VR-based nuclear radiation environment scene construction and man-machine interaction method

Abstract

The invention discloses a nuclear radiation environment scene construction and man-machine interaction method based on VR. The method comprises the following steps: calibrating a sensor; acquiring scene information in a nuclear radiation environment to generate a dense three-dimensional point cloud map; generating a three-dimensional scene model and a map through a three-dimensional curved surface reconstruction algorithm; fusing the nuclear radiation information to the three-dimensional scene map; modeling the robot in Unity 3D to obtain a virtual robot model; importing the three-dimensional scene model and the chartlet into Unity 3D, and optimizing the whole virtual scene in the Unity 3D; displaying the virtual scene and related parameters in unity 3D; and the robot entering the environment again to realize repositioning and real-time interaction. The VR-based nuclear radiation environment scene construction and man-machine interaction method provided by the invention has the characteristic of quickly and accurately modeling the nuclear radiation environment and a more immersive interaction mode, and can effectively deal with the tasks of emergency, maintenance, decommissioning and the like in the nuclear radiation environment.

Description

technical field [0001] The invention belongs to the technical field of scene reconstruction and human-computer interaction, and in particular relates to a VR-based nuclear radiation environment scene construction and human-computer interaction method. Background technique [0002] With the promotion and application of nuclear power generation, radiation and other industries, as well as the decommissioning of nuclear facilities and the extensive development of nuclear waste treatment and disposal, the risk of nuclear safety accidents such as nuclear leakage, nuclide proliferation, and loss of strong radioactive sources has increased. However, due to the restrictions of strong ionizing radiation, toxicity, and pollution in the nuclear environment, workers are often unable to directly enter the accident site. The three-dimensional fusion and reconstruction of nuclear radiation scene space and radiation information will help operators to analyze the nuclear radiation environment...

Problems solved by technology

[0006] At the current level of technology, although the robot has a certain intelligence, it is not enough to implement completely autonomous actions. The human-in-the-loop remote control is still an indispensable part of the current robot system towards practical applications.

However, the traditional remote control of robots mainly has the following problems: using display devices such as LCD screens to provide the operator with robot environment information, which makes the operator less immersive in the third perspective; the control of issuing motion-level instructions for the robot is not only inefficient And the interaction is not strong, which increases the difficulty of the operator's operation and easily makes the operator feel tired
