Problems solved by technology

The existing virtual reality devices on mobile platforms are mainly focused on the fields of user viewing, visual games, etc., but their advantages of not needing an external high-performance computer, no cables, and being mobile have not been well utilized.
After wearing a traditional virtual reality device (glasses), the user can only see the picture on the screen, but cannot see the surrounding environment, let alone analyze the surrounding environment

Embodiment

[0022] figure 1 It is a flow chart of the implementation of the fire scene simulation and analysis function based on augmented reality in an embodiment. The method includes:

[0023] 1. Obtain the surrounding dynamic scene by the binocular camera

[0024] The binocular camera is two cameras of the same model that are juxtaposed, and the distance between them is the same as the distance between the two eyes of a person, and the binocular camera must keep the same pace in terms of image transmission.

[0025] 2. Transfer the binocular scene image to the smartphone

[0026] A smartphone generally includes modules such as a central processing unit, a screen, a three-axis acceleration sensor, and a camera.

[0027] In this embodiment, the smart phone, as the core component of the augmented reality device, undertakes most of the tasks including image calculation, angle and direction sensing, and image output. Its functional structure is as follows: figure 2 shown.

Abstract

The invention discloses a fire scene simulation analysis device and method based on augmented reality, and belongs to the technical field of augmented reality equipment. The augmented reality scene isformed by superposing the following four layers: an environmental video acquired by a binocular camera, a real-time fire scene 3D model analyzed and constructed by using an SLAM algorithm, toxic gascomponents of combustible products after combustion, and a smoke flow direction in a fire; most functions of the whole augmented reality device can be realized by means of a smart phone, the user doesnot need to buy a whole set of equipment, the user can use less hardware cost investment to take the augmented reality dev ice as a fire escape drilling tool, the augmented reality device can also display possible combustible materials in the surrounding environment of the user, components of toxic substances after combustion and the flow direction of smoke in a fire, and has strong educational significance.

Description

technical field [0001] The present invention relates to the technical field of augmented reality equipment, in particular, to a fire scene simulation analysis device and method based on augmented reality. , wireless network and other components can provide users with fire scene simulation and analysis functions at a relatively low cost. Background technique [0002] At present, virtual reality devices on mobile platforms are generally composed of smartphones, general-purpose casings, binocular lenses, etc., and a few devices on the market are equipped with independent touch panels, three-axis acceleration sensors, etc., as controllers for interacting with users. The virtual reality devices on the existing mobile platforms are mainly focused on the fields of user viewing, visual games, etc., but their advantages of not needing an external high-performance computer, no cables, and being mobile have not been well utilized. After wearing a traditional virtual reality device (gl...
