Technical field

The utility model relates to wirelessly communicate, virtual reality, augmented reality and mixed reality technical field, be based particularly on The online VR/AR/MR integration helmet of more people of adaptive spectrum technology.

Background technique

In order to which VR technology is become mainstream technology, numerous manufacturers such as Google have put into a large amount of manpower and material resources and fund branch It holds, for example HTC is proposed Vive, Oculus is proposed CV1, and the happy mutually science and technology in the country, association, millet are proposed the respective helmet and produce Product；

All big enterprises' investment is so big, but why user has much without actively buying VR equipment, reason.VR The helmet be it is isolated, the thing that can be done is few.Many high-end helmets require connect to computer or game machine, when you explore When Mars, you want to have forgotten VR, but the cable on back and shoulder can interfere you.

Although the research and development facing lots of obstruction of wireless helmet display, on pursuing wireless road, we are still seen Many solutions having proposed or future can propose；

The mobile phone helmet occurred earliest is the wireless helmet display that we contact earliest.The mobile phone helmet is from Cardboard Start, is innately done to the optimal GearVR of experience, then to the all-in-one machine of smuggled goods everywhere by means of the mobile of chip for cell phone It has arrived wireless.Mobile phone helmet advantage be it is low in cost, disadvantage is a lack of that primary space orientation is supported and GPU performance is too low, can not Carry out complex scene and high quality rendering.For the mobile phone helmet under the constraint of current mobile GPU performance, optimal use scene is panorama Video is difficult to provide the stand-type above high quality immersion interactive experience；

The appearance of the series flow mobile phone helmet captures the virtual reality applications program video run on PC output result frame by frame (Capture), capture result is transferred on the mobile phone helmet or all-in-one machine after coding compression by wifi, by the mobile phone helmet Or all-in-one machine be decoded after be output to screen.The advantages of series flow mobile phone helmet is the intrepid video card resource that can be used on PC The high quality rendering of complex scene is carried out, the disadvantage is that Video coding decodes fairly time consuming, superposition wifi transmission can bring very long MotiontoPhoton delay, cause severe vertigo sense；And the picture after high quality rendering compresses meeting by Video coding Significantly reduce image quality；

We can also see some other wireless helmet, such as existing Daydream View of Google, Samsung Gear VR With HTC Vivo Foucs, their operational capability and display performance is not very by force, to be unable to complete the reality of complex scene and special efficacy When draw, often will appear Caton phenomenon, this greatly affected the feeling of immersion of user.It is delay first, qualified VR experience Transmission delay is required in 20ms, is easy for causing games personnel's dizziness more than this time；Followed by resolution ratio, at present VR The aobvious mainstream resolution ratio of head is 2.5k (2560*1440), has obvious " screen window lower than this resolution ratio in the case where meeting visual requirement Effect " destroys feeling of immersion；It is rendering capability again, the binocular rendering of VR can render the GPU of more consumption 70% or so, drop than monocular Low rendering capability can almost reduce image quality at double；

Current WiGig 60Ghz communication maximum can support 7Gbps to communicate, this is but also the video figure that the end PC is rendered It is possibly realized as being wirelessly transferred in a manner of raw data without compression.Lattice is global 60Ghz mould group maximum supplier, The mould group of offer can carry out the wireless transmission of closely (about 20 meters) to the data of 1920*1080@60fps.If used Nvenc hard coded and hard decoder, additional delay can also reach close to 20ms, this is disaster for VR experience；

So research and development can show VR/AR/MR, wireless receiving end, helmet power cabin, headset etc. combine support The integrated helmet of multi-user is extremely urgent, and technology is realized and is implanted into firstly the need of by high-end visual experience and head-tracking technology Wireless design is not necessarily to connecting cable when such user uses, more less, putting on the helmet can use obstacle when use；

By a large amount of experiment and research, it has been found that using the video signal wireless transmission after rendering is to realize wirelessly Thus the most direct method of Helmet Mounted Display proposes that one kind compresses directly progress based on wireless communication technique, without carrying out coding The solution of adaptive frequency dividing wireless transmission, the integrated helmet that will be developed with technique, including head show (VR/AR/ MR HMD), scenario simulation device, laser scanning location device (DBSLPD), radio transmitting device (MWTD) composition, new integration The helmet, for multi-user, logging in the virtual reality used, augmented reality and mixed reality situation provides solution simultaneously.

Below from the principle that beacon positions explain why in the application of large space beacon laser positioning is one more preferable Selection.

There are two base station in the beacon positioning system of HTC, there are two motor above each base station, one of motor is toward water Square to strafing, another is strafed towards vertical direction.

Base station refresh frequency be 60 hertz, the motor 1 above a of base station is strafed in the horizontal direction first, 8.33 milliseconds it Afterwards, second motor sweeps up (second 8.33 milliseconds) towards Vertical Square, and then base station a is closed, then base station b repetition and base The a that stands the same work ...

As long as have enough sensor points in this way in 16ms while being swept to by the light beam on vertically and horizontally, These sensor points are flat in projection relative to the sensor point that the angle of base station datum level can be computed, and be irradiated to Coordinate on face can also obtain.

Meanwhile when static these point coordinates in space be it is existing, can be used as reference, this makes it possible to calculate Out, rotation and translation of the point currently shone relative to datum mark further obtains the coordinate of these points, this is also one in fact A PnP problem.

Further, then the posture obtained on IMU is merged, it will be able to the accurate posture for providing the helmet and position.

The position of the helmet calculated in previous step and posture information are transmitted to be connected with PC one by RF and connect Receiving apparatus, the device pass through USB interface again, data are uploaded to driver the OpenVR runtime at the end PC, finally on It passes in game engine and game application.

Laser positioning technology, first is that it is at low cost, positioning accuracy is high, can the advantages such as distributed treatment, relatively expensive is infrared Motion capture camera, the cost for carrying out motion capture using laser light tower it is relatively low it is honest and clean it is enough, and almost without delay, Be not afraid of and block, speed is slow, compared with the disadvantages such as influencing vulnerable to natural light while, realize high-precision, the indoor positioning of high reaction speed. Second is that positioning accuracy is high, in the field VR, the positioning accuracy of superelevation means brilliant feeling of immersion.The precision of laser positioning scheme can To reach a millimeter rank, the shock effect of virtual reality experience has also just been achieved.In addition, compared to other two products, HTC Vive can allow for user's carry out activity in certain space, limit for user small, can be adapted to needs and walk about The game come.But due to the Laser emission base station of HTC Vive is that laser scanning located space is controlled using Mechanical course, And Mechanical course itself has that stability and durability are poor, therefore the stability and durability that cause HTC Vive are slightly Difference.

The active optical location technology of 2.Oculus Rift, principle is as shown in attached drawing 17；

Oculus is using the locating scheme based on Camera, referred to as Constellation.In Oculus Rift Infrared lamp (as mark point) has been covered with it on head is aobvious, has been flashed with the mode that some is fixed, these thermal cameras is exactly to take the photograph Install infrared light filter plate outside camera additional, such video camera can only be shot shows upper infrared lamp to the end, the aobvious surrounding ring so that filtering is turned around The visible light signal in border improves the signal-to-noise ratio for obtaining image, increases the robustness of system.

By special camera with fixed frequency (Oculus CV1 is a 60fps) shooting, one group of picture is obtained. System is by these two-dimensional positions on picture and the threedimensional model of the known helmet, and anti-point of releasing is in three-dimensional space In position.This process can further be subdivided into following step:

Firstly, in order to ensure accurately navigating to the LED on the helmet, the Oculus Camera software/driver at the end PC Some order is sent by HID interface and lights LED, and the sufficient brightness by Camera to be captured, while these LED are special with some Mode flicker.It is can ensure that in the case where blocking in this way, under a different angle, as long as there is enough LED to be clapped It takes the photograph, entire tracking system can work normally, and will not be influenced by the noise signal of other in environment.

Followed by record the position and direction for the LED that each is caught in.

Certainly, in order to carry out positioning, Oculus camera itself does not need the color of LED, need to only record each point Light and shade, so the image recorded in Oculus Camera firmware is 752 × 480 pixels, pixel format is Y8 ash Rank, each width figure seem as follows:

Position of the LED on the helmet on two-dimension picture is taken, and has the threedimensional model of Sensor on the helmet, has anything to do The problem of method is estimated that the three-dimensional position of these points, this is substantially a Pnp resolving (https: // En.wikipedia.org/wiki/Perspective-n-Point): having the model of n 3D point (just as above-mentioned 3D distribution of the LED point on the helmet), the set for the n 2D point that camera is filmed, along with the inside of camera itself Parameter, can extrapolate these point position coordinates (X, Y, Z) and posture (Yaw, Pitch, Roll).

Set of this point has much on earth, this is seek optimal solution the problem of, common way be n >=3, also As long as being the LED for photographing three or more on picture, it will be able to calculate relevant posture and position.In view of blocking or shooting Not clear etc. enough factors of photo, see in practice, at least to take 4-5 point, the posture of the entire helmet and position ability quilt It correctly calculates, this is also to be covered with a major reason of many LED points why on the helmet of Oculus.

The data calculated have how error solves, after a common method is the data for obtaining 6DOF, with the number According to the projection that tries again, new 2D image is generated, the image which starts with us for calculating is compared, obtains one A error function is calibrated using the function.But this brings another question: when point is compared, you why Know the point on 3d model, the matching relationship between the point on the two dimensional image taken, if done one-to-one complete If matching primitives, calculation amount is too big.So the method that Oculus is used is to carry out Rapid matching 3d using different flash patterns Point on point on model and the image taken.

Further, above the Attitude estimation the problem of, error is had by the posture that optics (camera picture) obtains, and This error mostlys come from the difficulty of the point identification on the photo captured when object fast moves.In order to reduce this mistake Difference needs to carry out the posture that a step calibration is resolved by PnP by IMU information, and here it is so-called Sensor data Fusion.

From the description above it can be seen that coming, the optical locating techniques based on camera, installation configures fairly simple, cost Also relatively low, but image processing techniques is complex, there is bigger difficulty in the position of identification object when object is mobile very fast, It is easy the interference by natural light simultaneously.

Finally, the distance for the photo that Camera itself can be captured is closer, need multiple cameras that can just be applied to Very big room location can only generally provide the VR positioning of desktop level.

In addition, Oculus Rift product is further provided with nine axle sensors, blocks or obscure in infrared optics positioning When, the spatial positional information of equipment is calculated using nine axle sensors.The positioning of+nine axis of Oculus Rift active infra-red optics System accuracy is higher, resists blocking property strong.Video camera as used in it has very high capture rate, and due to such system Mark point can always be obtained in the absolute location coordinates of current spatial, so accumulated error is not present.But nine axis can exist Apparent zero bias and drift, that can use its positioning letter obtained again when infrared optics positioning system can work normally again Breath calibration nine axis information obtained, so that infrared optics positioning mutually makes up with nine axis.

But due to camera limited viewing angle, the usable range of the product is limited, can largely limitation make The scope of application of user, thus be not available Oculus Rift and a wide range of movable reality-virtualizing game such as walk about to play needs. Also therefore, although Oculus Rift can support multiple objects while position that object can not be excessive, do not surpass generally Cross two.Certainly Oculus provides the scheme of three Camera recently, it is intended to position skill in room scale rank and beacon Art is played a decisive match.

The visible light active optical location technology of 3.PlayStation VR

What PlayStation VR was used is also optical alignment, and different from Oculus Rift, it is using visible Light active optical location technology.

The colorful light-emitting object tracking of PlayStation VR equipment PS Move using body-sensing camera and similar to before, Go to the position of positioning head part and controller.LED light ball, the aobvious each assembly one of every head can be put on head is aobvious.These LED light balls Can be with self-luminescence, and different photosphere issued light colors are different, it is photosphere and background environment, each in this way when camera is shot It can be distinguished well between a photosphere.PS3 uses single camera originally, by calculate radius of the photosphere in picture come It calculates position of the photosphere relative to camera, and finally determines the aobvious position of head.Therefore PS4 uses body-sensing camera, i.e., double Mesh camera calculates the 3 d space coordinate of photosphere using the picture that two cameras take.Concrete principle: theoretically It says, for a point in three-dimensional space, as long as this point can be simultaneously two video cameras findings, according to synchronization two The image of shot by camera and corresponding parameter, can determine location information of this of this moment in three-dimensional space.

After body-sensing camera, positioning accuracy, the robustness of PS4 has large increase.

Three-dimensional coordinate, i.e. x, y, z three degree of freedom are determined, PS series calculates the other three freedom degree using nine axis, And rotary freedom.

By above description it is recognised that PS can support multiple targets while position, and area is come with different colors Point.But since anti-the blocking property of PS is poor, once more personal uses are blocked mutually, then positions and receive influence at once.And And since the effective range of binocular camera is limited, so what the movable type of PS was limited, it can only live in camera usable range It is dynamic, it is used before substantially can only being sitting in PC machine.It, can due to still using although PS4 uses binocular camera at present Light-exposed positioning, so being highly susceptible to the influence of background color.In addition, being reflected according to user experience result, more quick acting In the case of will appear the problem of capture of camera is not caught up with.
