Description
Technical field
The present invention relates to VR technical fields, more particularly to a kind of VR ultrasound wave and infrared ray joint distance-measuring equipment and its
Method.
Background technology
Recent years, virtual reality (Virtual Reality, abbreviation VR) technology again went into the popular visual field, by VR
The helmet, user's body sense organ can be immersed in virtual world completely.But VR is interactively entering technical elements still Challenge.
Preferably experience to bring user, need accurate ranging localization to be carried out to user.Current ranging scheme is generally using round
Formula, i.e., realize range finding by detected reflectance signal after signal transmitting transmission.Also small part ranging scheme launches using one way
Receiving type, i.e., realize range finding by the transition time of accurate measurement signal.But these distance-finding methods are in signal detection process
In emitter and receptor need to be coupled together with wire, can just measure the transition time of signal, range unit was being arranged
Be limited by wire influence, installation site, complex installation process, actually used middle operation inconvenience.
The content of the invention
It is an object of the invention to overcome the shortcoming of prior art, there is provided a kind of ultrasound wave of VR and infrared ray joint are surveyed
Away from device and method thereof, its installation site is flexible, simple installation, easy to operate and simple structure, working stability.
To solve above-mentioned technical problem, following technical measures are present invention employs：A kind of ultrasound wave and infrared ray of VR
Joint distance-measuring equipment, including the transmitter module, detection module and receiver module that are arranged on the VR helmets；The transmitter module includes
Ultrasonic transmitter and RF transmitter；The receiver module includes ultrasonic receiver and infrared receiver；It is described to connect
Receive module to be connected with the detection module, which is disposed in the interior on fixture.
The present invention can also be further perfect by following technical measures：
Used as further improving, the receiver module and the detection module are correspondingly arranged on some groups, and which is fixed respectively
Diverse location indoors.
As further improving, in the detection module, intervalometer is provided with, for detecting ultrasonic receiver and infrared ray
Receptor receives the time of signal.
As further improving, display is also included, for showing range measurement.
A kind of distance-finding method is provided, its step includes：The transmitter module that S1 is arranged on the VR helmets is while launch ultrasound wave
Signal and infrared signal；The infrared receiver that S2 is disposed in the interior on fixture in receiver module receives the infrared ray
Signal；S3 detection modules detection receiver module receives the time of infrared signal；Ultrasonic receiver in S4 receiver modules
Receive the ultrasonic signal；S5 detection modules detection receiver module receives the time of ultrasonic signal；S6 detection modules
The time difference of receive information in calculating S3 and S6, and the distance of detection is calculated, display shows testing result.
As further improving, in S3 steps, infrared signal is received when detection module detects infrared receiver
When, the intervalometer started in detection module starts timing；In S5 steps, receive when detection module detects ultrasonic receiver
During ultrasonic signal, the intervalometer in detection module stops timing.
Compared with prior art, the present invention has advantages below：Using ultrasonic transmitter and RF transmitter as
One overall emission module, using ultrasonic receiver and infrared receiver as the receiver module of an entirety, examines in signal
During survey, detection module only need to be connected with receiver module, without the need for being connected with transmitter module, so that transmitter module and reception mould
Block is mutually independent, and device installation site is flexible, simple installation；As transmitter module is connected with detection module without the need for wire, user makes
With easy to operate during equipment；Multigroup receiver module is set, the distance between transmitting position and diverse location is can detect, by multigroup
Range measurement, it may be achieved positioning；Ultrasonic transmitter and RF transmitter are simultaneously emitted by signal, and detection module receives infrared
Start timing after line signal, after receiving ultrasonic signal, terminate timing, as the light velocity is far longer than the velocity of sound, receive infrared letter
Number with the time difference for receiving ultrasonic signal, can be considered the transition time of ultrasound wave, simple structure, working stability.
Description of the drawings
Fig. 1 is the structural representation that the ultrasound wave of VR of the present invention and infrared ray combine distance-measuring equipment.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the ultrasound wave of the VR of the present invention and infrared ray joint distance-measuring equipment, including transmitter module is set
10th, detection module 30 and receiver module 20, transmitter module 10 are arranged on the VR helmets.Transmitter module include ultrasonic transmitter and
RF transmitter,, used as an overall emission module, in ranging process, ultrasonic transmitter and RF transmitter are same for which
When respective signal is sent with fixed and identical time interval, for example ultrasound wave and infrared can be launched simultaneously with the frequency of 50Hz
Line.Receiver module 20 includes ultrasonic receiver and infrared receiver, and which is used as an overall receiver module.In the present embodiment
In, multigroup receiver module 20 is included, is respectively arranged on indoor fixture, such as ceiling, VR fixing equipments are first-class.Receive mould
Block 20 is connected with detection module 30, and in the present embodiment, the quantity of detection module 30 is corresponding with receiver module 20.Detection module 30
Intervalometer is provided with inside, for detecting that ultrasonic receiver and infrared receiver receive the time of signal.Display is included also
Device 40, for showing range measurement.In other embodiments, detection module 30 and display 40 also can each arrange one, inspection
Survey module 30 and detect multiple receiver modules 20 simultaneously, testing result is sent to into display 40 and is shown.
Ultrasonic transmitter and RF transmitter be simultaneously after transmission signal, as the light velocity is far longer than the velocity of sound, infrared ray
Receptor first receives infrared signal, and infrared signal was negligible from the transition time of emitter to receptor；Inspection
When surveying module 30 and detecting infrared receiver and receive infrared signal, start intervalometer and start timing；Then ultrasound wave connects
Receive device and receive ultrasonic signal, when detection module 30 detects ultrasonic receiver and receives ultrasonic signal, intervalometer
Stop timing；Intervalometer records the time difference of ultrasound wave receive information and infrared receiver information, as ultrasonic signal
Transition time Δ t.The known velocity of sound is 340m/s, then testing distance be velocity of sound 340m/s and ultrasonic signal transition time Δ t it
Product.Range measurement is transferred into display 40, can intuitively read range measurement by display 40.
When user wears the VR helmets, 10 transmission signal of transmitter module being arranged on the helmet, fixed indoors multigroup connect
Receive module 20 to start simultaneously.The data detected using multigroup receiver module 20, VR device controllers can be calculated by computing
The positional information of transmitter module 10, and then accurately realize that user positions.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvements done etc. are should be included within the scope of protection of the invention.
