Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this
Bright it is described in further detail, it is clear that described embodiment is only a part of embodiment of the present invention,
Rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out all other embodiments obtained under creative work premise, broadly fall into the scope of protection of the invention.
As it is shown in figure 1, the display packing schematic diagram being suitable for by the embodiment of the present invention, wherein, target device
In have two graphics processing units, the respectively first graphics processing unit 101 and the second graphics processing unit
102, wherein, target device can be VR equipment, it is also possible to VR equipment by wired or wireless
The computer equipment that mode is attached, the first graphics processing unit 101 is mainly used according to VR equipment
Positional information carries out image rendering and generates picture frame, then the picture frame of generation is stored shared memory space
103, the second graphics processing unit 102 from shared memory space 103, obtain picture frame, and according to figure
As the display screen of VR equipment is carried out refreshing display by frame.
Wherein, when target device is VR equipment itself, VR equipment can complete image rendering to image
The all working that frame refreshing shows, now VR equipment is an equipment with independent image disposal ability；
When target device is a computer equipment, then VR equipment is by the way of wired or wireless and computer
It is attached, is then completed image rendering work by computer equipment, and send to VR after generating picture frame
Equipment carries out refreshing display, and now, VR equipment is only responsible for receiving the figure that computer equipment constantly sends over
As frame, show, and not responsible render work.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As in figure 2 it is shown, the display packing that the embodiment of the present invention provides, including:
The first graphics processing unit in step 201, target device is according to the VR device location letter got
Breath, renders and generates picture frame to be shown, and is copied to described picture frame to be shown share memory space；
The second graphics processing unit in step 202, described target device is according to described VR equipment during display
Current location information adjust the picture frame in described shared memory space, and the picture frame after adjusting shows
At described VR equipment.
First graphics processing unit, according to the VR device location information got, renders and generates figure to be shown
As frame, it is then copied to share in memory space, and the second graphics processing unit is from shared memory space
Obtain picture frame then to show on VR equipment, but owing to the first graphics processing unit generates image
The frequency of frame and the second image procossing display picture frame (i.e. the frequency of VR equipment display picture frame) not phase
With, such as generate the frequency of picture frame less than the second image procossing display picture frame when the first graphics processing unit
Time, then causing the picture frame that likely the second graphics processing unit gets from shared memory space is last time
The picture frame obtained, the picture frame i.e. sharing memory space does not have enough time to update, now by
The above-mentioned steps 201 of the present invention～the method for step 202, may be implemented in the figure shown on VR equipment after adjusting
As frame.
Specifically, the first graphics processing unit is responsible for generating picture frame according to VR device location information and storing
In shared memory space, and in above-mentioned steps 202, and the second graphics processing unit is according to VR equipment
Current location information adjust the picture frame in described shared memory space, and the picture frame after adjusting shows
At described VR equipment.
Specifically, the picture frame in the shared memory space that the second graphics processing unit gets is divided into following two
Kind situation:
Situation one, described picture frame are that the current location according to VR equipment renders generation
If the second graphics processing unit determines that the picture frame in shared memory space is to render according to current location
Generate, then directly this picture frame is shown as the picture frame after adjustment, the picture frame after then adjusting
At described VR equipment.
Under this situation, when user's head rotation, reach new position, now first image procossing
Unit renders according to this new position and obtains a new picture frame, and this picture frame is at the first image procossing
Unit obtains before picture frame to shared memory space, is stored on sharing in memory space, therefore when the
One graphics processing unit when shared memory space obtains picture frame, get to be one be exactly the newest
Picture frame corresponding to position, thus directly this picture frame is shown.
Situation two, described picture frame are not that the current location according to VR equipment renders generation
Under this situation, the picture frame in the shared memory space that the first image procossing gets is not according to current
Position renders generation, is i.e. to be generated, due to the first graphics processing unit according to VR position before
Render the frequency speed less than the second graphics processing unit display picture frame of new picture frame, therefore when second
When graphics processing unit wants to show a two field picture, get from shared memory space remain before
Picture frame through showing, if now directly shown by this picture frame, then can cause user currently
The picture frame that moment is seen is identical with the picture frame that a upper moment is seen, thus causes motion blur phenomenon occur, very
To being the situation that can cause user that dizziness occurs.
Therefore, for solving this problem, the picture frame in the second graphics processing unit determines shared memory space
Generation is not rendered, then according to current location information and the shared storage sky of VR equipment according to current location
Picture frame between generates intermediate frame, and using intermediate frame as the picture frame after adjustment.I.e. according to VR equipment
Current location information and the picture frame that gets, generate an intermediate frame, then using this intermediate frame as tune
Picture frame after whole, and the picture frame after described adjustment is shown, alternatively, at described second image
Reason unit generates according to the picture frame in the current location information of described VR equipment and described shared memory space
Intermediate frame, including: described second graphics processing unit determine described VR equipment from described a position to institute
State rotation amount and the translational movement of current location, according to described rotation amount and described translational movement, described picture frame is entered
Row rotates and translation, obtains described intermediate frame.
For example, user is when putting on VR equipment, and head current location is A, when user has done one
When the action of quick rotation head arrives B, cause the first graphics processing unit owing to user's head rotation is too fast
Having little time to render out by a up-to-date two field picture frame, now the second graphics processing unit is according to the present bit of user
Put an A and upper position B, obtain rotation amount and the translational movement of user's (namely VR equipment), thus base
In the rotation amount obtained and translational movement, to the picture frame in shared memory space, (this picture frame is showing
Showed at least one times) rotate accordingly and translation, thus obtain intermediate frame.
Owing to, in reality, a two field picture may be bigger than the display screen of VR equipment, it is also possible to sets with VR
Standby display screen size is identical.
When a two field picture is bigger than the display screen of VR equipment, the most only partial information is displayed on VR equipment
On, when generating intermediate frame, actually see is the image information not shown before of picture frame,
Such as, in a two field picture, left position shows river, shows a personage in centre position, on the right side
Limit position display has an animal, then only may can show on VR equipment and see a personage, and left
The river of position, limit and the animal of location right will not be simultaneously displayed on VR equipment, when raw by said method
When becoming intermediate frame, if user's head is on the left of turning to, then the intermediate frame of generation actually shows
Content is exactly river, if user's head turns to right side, then the intermediate frame of generation actually shows
Content is exactly animal.I.e. intermediate frame obtains after carrying out rotating and translating based on existing picture frame；When
When one two field picture is equal in magnitude with the display screen of VR equipment, then the intermediate frame of generation can be previous frame figure
The partial content of picture, then refills part black image, generates an intermediate frame.
Alternatively, described first graphics processing unit is created by first thread, described second graphics processing unit
By the second thread creation；After the first graphics processing unit generates picture frame, by first thread by first
Picture frame to be shown is copied to shared memory space by graphics processing unit, and will be altogether by the second thread
Enjoy the picture frame in memory space and be sent to the second graphics processing unit.
In actual applications, the first graphics processing unit and the second image procossing unit can be to have at image
The unit of reason ability, such as, can be some image processing software modules etc., alternatively, described second thread
Created by described first thread；And described first graphics processing unit is DirectX equipment, and/or institute
Stating the second graphics processing unit is DirectX equipment.
Wherein, DirectX (Direct eXtension is called for short DX) is that the multimedia created by Microsoft is compiled
Journey interface.Being realized by C++ programming language, be widely used in electronic game exploitation, DirectX is so
One group of technology: they are intended to make computer based on Windows become operation and display has abundant multimedia
