Problems solved by technology

[0005] The simulation of the on-site environment through the on-site video method cannot show the real-time status of the on-site signal equipment (signal machine, turnout, screen door, etc.), and the train driver does not have an accurate grasp of the on-site environment
Moreover, the visual scene generated by the video recording method is a two-dimensional display of the on-site environment, which cannot provide users with an intuitive, vivid and immersive sensory experience.
Therefore, the training effect of the CBTC training system based on this method is very low

Abstract

The invention relates to computer simulation and provides a three-dimension visual simulation method and a three-dimension visual simulation system for driving simulation. The method specifically comprises the following steps: loading a three-dimension scene model for running of a train along a track; refreshing a running image, in which a user drives the train, output to the user at a fixed frequency, wherein each refreshing includes correspondingly updating the three-dimension scene model according to a scene state input signal and correspondingly updating the signal machine state in the three-dimension scene model according to a signal machine state input signal; calculating the viewpoint and the view angle of the user in the three-dimension scene model at the current moment according to a movement state input signal of the train; and refreshing the running image, in which the user drives the train, output to the user according to the updated three-dimension scene model as well as the viewpoint and the view angle. High-fidelity three-dimension visual simulation in different environments is realized, which can help improve the training effect of CBTC training.

Description

technical field [0001] The invention relates to communication technology, in particular to a three-dimensional visual simulation method and system for simulating driving. Background technique [0002] The domestic CBTC system (Communication Based Train Control System, train control system based on wireless communication) is an automatic train control system, based on the principle of moving block train intervals, to realize the control of trains, mainly applicable to subway and light rail systems. The system control level in the domestic CBTC system supports a variety of control modes, from inter-station block based on semi-automatic block to point control level based on fixed block principle and transponder, to the use of high-precision train positioning, train-ground continuous two-way communication CBTC control level. It can cover the operation of different levels of automation under the same signal system, the mixed operation of different types of trains and the applica...
