Fig. 1 is according to a kind of a kind of flow chart of embodiment of image reading method of the present invention.
According to Fig. 1, which comprises the following steps：
Step S110, by the first left-side images of the first camera acquisition and the first right part of flg of second camera acquisition
As being stored in first buffering area.
Wherein, the first camera is the camera of acquisition left-side images, and second camera is the camera shooting of acquisition image right
Head, the first left-side images and the first image right are the left-side images and image right being stored in first buffering area.First is slow
It can be established in the memory of virtual reality device for storing the memory space of image data to rush area.
Specifically, the step that the first left-side images and the first image right are stored in first buffering area is at HAL layers
It is performed in (hardware abstraction layer), the first left-side images and the acquisition modes of the first image right are with call back function in HAL layers
Form obtained from driving layer.
Step S120 judges the first synchronous left-side images and the first image right whether are stored in first buffering area,
If so, step S130 is then performed, if not, continuing to execute step S110.
Specifically, it (can be that the first left-side images or first are right that first image is often stored in first buffering area
Side image), be carried out a step S120, with ensure in first buffering area a pair of the first synchronous left-side images of at most storage and
First image right.
Further, the specific method for performing step S120 can be the acquisition moment and first for judging the first left-side images
Whether the time difference between the acquisition moment of image right is less than preset threshold value, if so, then judging the first left-side images
It is synchronous with the first image right.
Step S130 reads the image of first buffering area memory storage.
Specifically, it is the first image of a pair that application program reads first buffering area memory storage, including one first left side
Image and first image right, and according to the first left-side images of reading and the sky of the first image right progress luminescent device

Step S160 reads the image of second buffering area memory storage.
Specifically, it is the second image of a pair that application program reads second buffering area memory storage, including one second left side
Image and second image right, and according to the first left-side images of reading and the sky of the first image right progress luminescent device
Between position.
Since after execution of step S130, what application program was read is the first image in first buffering area domain, that
, for the left-side images and image right that the image for ensureing application program reading next time is synchronization, can be will be not synchronous
Second left-side images and the second image right are stored in second buffering area.It is left to treat that second buffering area memory is placed with synchronous second
When side image and the second image right, then read the image in second buffering area.
In this way, the image reading method by the present invention, it is possible to ensure that every a pair of of image that application program is read all is
Synchronous acquisition, avoid the occurrence of due to image it is asynchronous caused by Wrong localization the problem of.Moreover, often storage is a pair of in buffering area
Synchronous left-side images and image right will read this pair of of image, and the image that can cause buffering area memory storage is less, can
To reduce the time delay between the storage of image and reading.
In one particular embodiment of the present invention, in buffering area the left-side images of storage can have one or multiple,
The image right of storage can also have one or multiple.HAL layers are to obtain left-side images and right side respectively using two threads
Image, moreover, left-side images and image right that two cameras are gathered simultaneously are synchronized at HAL layers.It is but right
In the left-side images and image right of acquisition simultaneously, may cause to exist in storage to buffering area due to the problems such as equipment performance
At the time of it is different either occur left-side images or image right not successfully in storage to buffering area the problem of, if read
Left-side images and image right are asynchronous, are present with difference when determining luminescent device position according to left-side images and image right
It is wrong.The left-side images mentioned in the embodiment of the present invention, which include the first left-side images and the second left-side images, image right, to be included
First image right and the second image right, buffering area include first buffering area and second buffering area.
On this basis, nonsynchronous first left hand view in first buffering area can also be deleted before step S130 is performed
Picture and the first image right.Nonsynchronous second left-side images in second buffering area can also be deleted before step S160 is performed
With the second image right.
For example, the first camera acquires the first left-side images 1 at the first moment, second camera gathers at the first moment
First image right 1, still, if the first left-side images 1 have been stored in first buffering area, and the first image right 1 is lost
Mistake fails storage in first buffering area, it will the first left-side images 2 for again gathering the first camera at the second moment and the
Two cameras acquire the first image right 2 at the second moment and store to first buffering area, it can be determined that go out the first left hand view
As 2 acquisition, the moment is identical with the acquisition moment of the first image right 2 or the acquisition moment and first of the first left-side images 2
Time difference between the acquisition moment of image right 2 is less than threshold value, then, then it can be determined that the first left-side images 2 and first are right
Side image 2 is synchronous, then, then the first left-side images 1 are deleted in first buffering area, and perform step S120.
For another example the first camera acquires the second left-side images 3 at the 3rd moment, second camera is adopted at the 3rd moment
Collect the second image right 3, still, if the second left-side images 3 have been stored in second buffering area, and the second image right 3
Loss fails storage in second buffering area, it will the second left-side images 4 for again gathering second camera at the 4th moment and
The second image right 4 that 4th camera gathers at the 4th moment is stored to second buffering area, it can be determined that goes out the second left side
Moment is identical with the acquisition moment of the second image right 4 or the acquisition moment of the second left-side images 4 and for the acquisition of image 4
Time difference between the acquisition moment of two image rights 4 is less than threshold value, then, then it can be determined that the second left-side images 4 and second
Image right 4 is synchronous, then, then the second left-side images 3 are deleted in second buffering area, and perform step S140.
In one particular embodiment of the present invention, camera framework MMCamera is located at HAL layers, is taking the photograph for high-pass platform
As head framework, the image reading method of the present embodiment synchronizes left image data and right image data at HAL layers.It takes the photograph
As the head framework MMCamera threads for receiving left-side images and image right from driving are producer producter, to buffering area
