Abstract

The invention discloses a method for docking a virtual steering wheel and a real steering wheel in a virtual driving application, comprising: creating a virtual steering wheel and a reference point, and simultaneously creating a link handle connecting the virtual world and the real world; obtaining sampling point data; and calculating the position of the real steering wheel in the virtual world Coordinates (position, orientation); output handle sampling calibration results; save the handle sampling calibration results, calculate the relative coordinates (position, orientation) of the real steering wheel center and the virtual steering wheel center in the virtual world coordinate system; correct the virtual world coordinate system. The present invention can replace the original virtual equipment space calibration method, use the steering wheel of the real world driving simulator as a calibration reference object, calculate the center point position and orientation of the corresponding steering wheel in the virtual space, and correct the virtual world coordinate system, thereby realizing the virtual reality space Positioning can realize simulated driving simulation in virtual reality and enhance the driving simulation experience.

Description

technical field [0001] The invention relates to the technical field of virtual driving simulation, in particular to a method for docking a virtual steering wheel and a real steering wheel in virtual driving applications. Background technique [0002] Virtual driving refers to the use of modern high-tech means to allow the experiencer to experience a car driving experience that is close to the real effect of vision, hearing and somatosensory in a virtual driving environment. Also known as car driving simulation, or car simulation driving. [0003] In the traditional virtual driving solution, the six-degree-of-freedom simulation device is used for docking. Common display devices, such as large-screen LOD displays, can realize virtual driving simulation, but lack of realism and immersion, and the simulation effect is not good. At this stage, using VR virtual reality equipment to replace the output of LOD display equipment can greatly enhance the virtual driving simulation effe...
