Description
Technical field
The present invention relates to augmented reality equipment technical fields, specifically, being related to a kind of Fire Field based on augmented reality
Scape sunykatuib analysis device and method, the device and method can be can be realized using conventional mobile phone, utilize screen existing in mobile phone
The components such as curtain, sensor, wireless network can provide fire scenario sunykatuib analysis function with less cost for user.
Background technique
Currently, the virtual reality device of mobile platform is generally made of smart phone, general shell, binocular lens etc., city
A small number of devices can also be equipped with independent Trackpad, three axis acceleration sensors etc. on face, generate the controller interacted as with user.
The virtual reality device of existing mobile platform is principally dedicated to the fields such as user's viewing, vision game, but its do not need it is external
High-performance computer, without cable, moveable advantage, there is no use well.User puts on traditional virtual real device
After (glasses), the picture in screen can only see at the moment, cannot see that the environment of surrounding, surrounding enviroment can not be divided
Analysis.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of fire scenario simulation based on augmented reality
Analysis method.
The technical solution adopted by the invention is as follows:
A kind of fire scenario analog analysing method based on augmented reality, includes the following steps:
Step 1: ambient video is acquired by binocular camera；
Step 2: the ambient video acquired according to binocular camera is built into real-time fire scenario with the analysis of SLAM algorithm
3D model；
The combustible material in method for distinguishing identification scene is known with image texture, and flame, smog special efficacy are superimposed to it；
According to the noxious gas component after the burning of the material analysis of combustible material, and shown；
In conjunction with scene spatial model and real-time wind direction, the flow direction of smog in fire is shown；
Above-mentioned superimposed video is exported as a result to screen；
Step 3: the gesture model that gesture sensor identifies being superimposed upon on augmented reality video, and makes to establish in scene
On dummy model to gesture command generate interaction feedback.
A kind of fire scenario sunykatuib analysis device based on augmented reality, including binocular camera, structure light gesture sensing
Device, screen, processor, binocular camera acquires ambient image information, and is transmitted to screen and processor, and processor superposition is virtual
In scene to ambient image, formed augmented reality scene, structure light gesture sensor detection gesture information, be transmitted to processor into
Row processing, executes as interactive command.
The beneficial effects of the present invention are:
The present invention uses augmented reality device and method, and user can be allowed to be put into less hardware cost, largely borrowed
The existing hardware sensor of smart phone is helped, complete equipment is not needed to buy.When using the augmented reality equipment of mobile platform, face
Pair will be the one and half true half virtual worlds, have stronger deeper feeling of immersion, ambient enviroment can be perceived when in use,
User can arbitrarily walk with augmented reality equipment.Tool, augmented reality dress of the invention are drilled as a kind of fire disaster escaping
Set after can also showing possible combustible in user's surrounding enviroment and burning smog in the ingredient and fire of noxious material
Flow direction, have stronger moral.

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, with reference to embodiments and its attached drawing is to this hair
It is bright to be described further.
Embodiment
Fig. 1 is the flow chart that the fire scenario sunykatuib analysis function in one embodiment based on augmented reality is realized.The party
Method includes:
1, surrounding dynamic scene is obtained by binocular camera
Binocular camera is the camera of two same models arranged side by side, and the distance between its spacing and people two is identical, and
Binocular camera will keep step completely the same in terms of image transmitting.
2, by binocular scene image transmitting to smart phone
Smart phone generally comprises the modules such as central processing unit, screen, 3-axis acceleration sensor, camera.
In the embodiment, core component of the smart phone as augmented reality device is undertaken including image operation, angle side
It is as shown in Figure 2 to most of task, functional structures such as sensing, image outputs.
Its step specifically: the collected binocular image of binocular camera in equipment passes through mobile phone as unit of frame
OTG interface is transmitted to mobile phone, is analyzed as the central processing unit built in smart phone with SLAM algorithm, constructs week in real time
Enclose the spatial model of dynamic scene.
3, different special efficacys is added for augmented reality scene
According to the difference of augmented reality scene, need to make different degrees of modification, superposition to model of place by software.
For example, software can be transported according to the model of place constructed in real time in the augmented reality scene of simulated fire escape
Method for distinguishing is known with image texture, identifies article flammable in scene around, on it superposition simulation flame, smog special efficacy.
4, in conjunction with space fluid model, special efficacy is calculated in real time
In the embodiment, in the scene of simulated fire escape, the combustible materials that augmented reality system simulates burn fiery
Flame, dense smoke follow fluid motion physics law, and (concrete methods of realizing can be found in " research of the fluid emulation in fire scenario simulation
With realization " Song's height), and can be with model of place flowing around.The ingredient of its pernicious gas generated after burning can be with difference
The form of color is distinguish in augmented reality scene.
5, user gesture is obtained by gesture sensor.
Gesture sensor uses structure light principle, is added by an infrared laser point cloud emitter and an infrared camera
Filter set is at infrared laser point cloud is irradiated to user's hand, and the image of reflection is received with infrared camera, identifies its texture
It rises and falls, the model of user gesture can be generated.Its finger movement is analyzed again, can be translated as gesture interaction order.
6, gesture model is superimposed upon in augmented reality scene
The model of user gesture is transferred to smart phone by mobile phone OTG interface, true in calculate generation half virtual half
Augmented reality scene on, superposition gesture model simultaneously can recognize that gesture, the movement such as push away, draw, losing, grabbing, clapping hands, as
Interactive command executes, on Real-time Feedback to final user interface.
The image that end user is seen is made of four figure layers of different levels, by smart phone screen through saturating
Mirror shows, as shown in Figure 3.
