The executive agent for the image write-in control method that example provides can be wear-type virtual reality device, as shown in figure 1, this method
Comprise the following steps：
S101, the first reading caused by the read operation triggered in response to display module to nth frame image in buffer queue
State, time variable value corresponding to the first reading state of renewal is the triggered time corresponding to the first reading state.
After wear-type virtual reality device is opened, the display module in wear-type virtual reality device can regularly be sent
Image reading signal.Display module can control the reading of image to start and terminate according to this image reading signal, alternatively,
In practical application, conventional image reading signal can be vertical synchronizing signal.
Display module in response to image reading control signal by triggering the reading to the nth frame image in buffer queue
Operation, display module can also produce the first reading state while this read operation is triggered.Alternatively, the read operation of triggering
Can represent that the operation that image reading starts can also represent the operation that image reading terminates, accordingly, this first reading
State can be to read beginning state, represent that nth frame image starts to read；It can also be to read done state, represent nth frame figure
As having read completion.
Wear-type virtual reality device can get triggering and be directed to nth frame image in response to this first reading state
Read operation triggered time, triggered time of this read operation that is to say that the first reading state caused by read operation is corresponding
Triggered time.Afterwards, wear-type virtual reality device can according to corresponding to the first reading state got triggered time
Update time variable value corresponding to the first reading state.It is involved as described above, because the first reading state can be
It can also be to read done state to read beginning state, and therefore, time variable value corresponding to the first reading state after renewal has
May represent be nth frame image the reading time started, it is also possible to expression be nth frame image the reading end time.
S102, according to time variable corresponding to time variable value corresponding to the first reading state and current second reading state
The time order and function relation of value, determine whether nth frame image reads and finish.
S103, if nth frame image reading finishes, N+1 two field pictures are write in buffer queue.
Wear-type virtual reality device can according to by renewal the first reading state corresponding to time variable value and
Time variable value corresponding to the second current reading state determines whether nth frame image reads and finishes, current the herein be related to
Time variable value corresponding to two reading states is existing before time variable value corresponding to the first reading state is updated
One time variable value.It should be noted that in practical application, the first reading state and the second reading state are two different
Reading state.Alternatively, if the first reading state is reads beginning state, the second reading state is reading done state；If
First reading state is reads done state, then the second reading state is reading beginning state.
When the time that time variable value expression nth frame image reading corresponding to the first reading state starts, second reads shape
Time variable value corresponding to state represents that N-1 two field pictures read the time terminated, then time variable corresponding to the first reading state
Value is more than time variable value corresponding to the second reading state, now, shows that nth frame image is read out.Now, wear-type
Virtual reality device keeps current wait state, and N+1 two field pictures will not be read from buffer queue.
When the time that time variable value expression nth frame image reading corresponding to the first reading state starts, second reads shape
Time variable value corresponding to state represents the time that nth frame image reading terminates, then time variable value corresponding to the first reading state
Less than time variable value corresponding to the second reading state, now, show that nth frame image has been read and finish, now, wear-type is empty
Intending real world devices can continue to write N+1 two field pictures in buffer queue.
In the present embodiment, the display module of wear-type virtual reality device can be read nth frame image triggering in buffer queue
Extract operation simultaneously produces first reading state simultaneously.Then, head-mounted display apparatus is in response to caused by this read operation
It one reading state, that is to say the triggered time corresponding to the first reading state, recycle so as to obtain the triggered time of read operation
Triggered time corresponding to first reading state updates time variable value corresponding to the first reading state.Read according to the first of renewal
Precedence relationship between time variable corresponding to time variable corresponding to state and the second current reading state determines to wear
Whether formula virtual reality device has finished nth frame image reading.It that is to say that wear-type virtual reality device is write to image
Entering operation is controlled by the performance of image reading.If the read operation of image has been completed, wear-type virtual reality
Equipment can just start to write N+1 two field pictures in buffer queue；If the read operation of image is not completed, wear-type is virtual
Real world devices can be waited for, and not carry out write operation to image.So can with ensure the reading of image and write-in all
It is respectively completed, is not in the situation of read/write conflict, avoids the occurrence of picture tear, improve the quality that image is shown.
Fig. 2 is the flow chart of image write-in control method embodiment two provided in an embodiment of the present invention, as shown in Fig. 2 should
Method comprises the following steps：
S201, the first reading caused by the read operation triggered in response to display module to nth frame image in buffer queue
State, time variable value corresponding to the first reading state of renewal is the triggered time corresponding to the first reading state.
Above-mentioned steps S201 implementation procedures are similar to the corresponding steps of previous embodiment, may refer to implement as shown in Figure 1
Or else associated description in example, is repeated herein.
S202, according to time variable corresponding to time variable value corresponding to the first reading state and current second reading state
The time order and function relation of value, determine whether nth frame image reads and finish.
According to the associated description in embodiment one, the first reading state and the second reading state are two different reading shapes
State.It is readily conceivable that, it may appear that following two situations：When first reading state is reads beginning state, the second reading state
To read done state；When first reading state is reads done state, the second reading state is reading beginning state.
Now, when the first reading state is reading beginning state and the second reading state is to read done state, first
Time variable value corresponding to reading state is to read time variable value corresponding to beginning state, when corresponding to the second reading state
Between variate-value be read done state corresponding to time variable value.Associated description in embodiment one can obtain：If
Read time variable value corresponding to beginning state and be less than time variable value corresponding to reading done state, it is determined that nth frame image
Reading finishes.
When the first reading state is reading done state and the second reading state is to read beginning state, first reads shape
Time variable value corresponding to state is to read time variable value corresponding to done state, time variable corresponding to the second reading state
Value is to read time variable value corresponding to beginning state.Similarly, the associated description in embodiment one can obtain：If
Read time variable value corresponding to beginning state and be more than time variable value corresponding to reading done state, it is determined that nth frame image
Read.
S203, if nth frame image reading finishes, generate N+1 two field pictures.
It is different from watching common image, scene that user watches in virtual scene build in advance, 360 ° and
The posture of user is closely related.Therefore, it is necessary to real-time according to the current posture of user after nth frame image reading
Generate N+1 two field pictures to be written.
Alternatively, after nth frame image reading, wear-type virtual reality device can generate in the following manner
N+1 two field pictures：
First, the attitude data of user is obtained.
And then determine to be located at user's field range according to the position of each object in attitude data and virtual reality scenario
Interior object.
Finally, generation is with being located at user's corresponding N+1 two field pictures of object within sweep of the eye.
Specifically, nine axle sensors being configured in wear-type virtual reality device can be gathered with default acquisition interval
The attitude data of user.Alternatively, this attitude data can be stored in a fixed memory space.Wear-type virtual reality
Equipment can be to get the current attitude data of user, alternatively from this memory space, and the attitude data collected can be with
For the attitude data of user's head, such as the angle of pitch of user's head, deflection angle and course angle.
In 360 ° of virtual reality scenario, the field range of user is limited, and field range can pass through visual angle
Size is measured, and the eyes visual angle of adult is generally 110 ° or so.Meanwhile after the completion of virtual reality scenario is built, wear-type
Virtual reality device can be to know the position coordinates of each object in virtual reality scenario, it is alternatively possible to by virtual scene
In each object position coordinates write a file in.Therefore, what wear-type virtual reality device can be current according to user
Attitude data determines the coordinate range corresponding to user's field range, and filters out from file that to belong to user within the vision
Object.Finally, wear-type virtual reality device can be with according to the object generation N+1 two field pictures filtered out.
S204, N+1 two field pictures are write in buffer queue.
After nth frame image reading, wear-type virtual reality device can with by the N+1 two field pictures of generation write
In buffer queue.
In addition, the image shown in wear-type virtual reality device all has stereoeffect, this stereoeffect
It is by by two there is the left-eye image of parallax and eye image to be synthesized and caused.Want normally to show that a frame has
The image of stereoeffect just needs to read and render left-eye image and eye image respectively, that is to say needs respectively to left-eye image
Controlled exactly with the opportunity of eye image write-in.
In order to control the opportunity that left-eye image and eye image write exactly, it is alternatively possible to which buffer queue is drawn
It is divided into two spaces, that is, is used for the first space for storing left-eye image and the second space for storing eye image.Wherein, on
Text and the nth frame image and N+1 two field pictures that are hereinafter related to can be left-eye image simultaneously or be right simultaneously
Eye pattern picture.
If it is nth frame left-eye image to read the nth frame image finished, N+1 frames left-eye image is write into buffer queue
The first space in.If it is nth frame eye image to read the nth frame image finished, N+1 frames eye image is write and cached
In the second space of queue.
Herein it should be noted that the present invention is not defined to the order of image reading, corresponding to a two field picture
Left-eye image and during eye image is read out, can first read left-eye image or first read right eye figure
Picture.
In the present embodiment, the image for carrying out writing control is to need to be generated in real time according to the attitude data of user,
The attitude data that content that user watched by wear-type virtual reality device and user can so be ensured is matching.So
The left-eye image generated in real time and eye image are respectively written into buffer queue again afterwards.This buffer queue is to have carried out simultaneously
Space division is crossed, that is to say and buffer queue is divided into the first space and second space, and the first space and second space
It is respectively used to store left-eye image and eye image.It can so avoid occurring left-eye image and eye image being cached in jointly
The situation of the image reading mistake easily occurred in one buffer queue for not dividing space, for example, left eye figure should be read
As when but mistakenly have read eye image, allow that wear-type virtual reality device is more independent, controls image exactly
Write-in opportunity.
