Law enforcement scenario simulation system and method

Abstract

The invention provides a law enforcement scenario simulation system and method. The system includes a display mounted at the head of a user, a simulation gun held at the hand of the user, a scenario setting handle which is used for selecting a law enforcement scenario, a host, and a positioner, wherein the display, the simulation gun and the scenario setting handle are provided with photosensitivesensors respectively. According to the law enforcement scenario simulation system of the invention, the positions of the display, the simulation gun and the scenario setting handle in a current scenario can be sensed; scenario display is performed in the display; and the simulation gun includes a holster, a safety switch for preventing fire escape, a trigger switch, a muzzle magnetic switch, a vibrator, a mechanical trigger, and a tracker, wherein the tracker is provided with the photosensitive sensor. According to the law enforcement scenario simulation method of the invention, a gun structure simulates a real gun and enables gun drawing, triggering pulling and safety protection just as the real gun can do; real-time simulation conditions can be displayed on the display mounted at the head of the user; and therefore, the realness of simulation can be improved.

Description

technical field [0001] The invention relates to the field of VR simulation, in particular to a law enforcement scenario simulation system and method. Background technique [0002] Virtual reality (Virtual Reality) simulation (simulation) technology, or called simulation technology, is to use a system to imitate another real system technology. Virtual simulation is actually a computer system that can create and experience a virtual world (Virtual World). This kind of virtual world is generated by computer, and it can be a reproduction of the real world or an imaginary world. Users can interact naturally with the virtual world through various sensory channels such as vision, hearing and touch. It creates a 3D virtual world that reflects the changes and interactions of physical objects in real time for users in a simulated way, and provides users with a 3D virtual world that observes and interacts with the virtual world through auxiliary sensing devices such as head-mounted di...

AI Technical Summary

Problems solved by technology

[0004] Firstly, it is impossible to simulate the action of drawing and retracting the gun. When drawing and retracting the gun, the simulated gun needs to be pulled out or inserted from the holster. HTC Vive simulates the gun through its own handle, but the built-in handle cannot be simulated due to its structural characteristics. Insert it into the holster (the head is relatively large and cannot be inserted or pulled out smoothly; in addition, when inserted into the holster, the positioning structure of the head cannot be searched by the locator), and the signal when it is pulled out cannot be obtained

[0005] Second, it is impossible to simulate the operation action and loading action of the safety switch. The structure of the gun determines the standardization of its operation process. Since the safety switch needs to be opened and loaded before shooting, the action simulation cannot be provided when using the handle.

[0006] The third is that it is impossible to simulate the feel of the gun. Because the handle is light and the position of the center of gravity is too different from that of the real gun, it is difficult for the experiencer to achieve the real feeling of holding the gun during the simulation.
