Description
Technical field
It is more particularly to a kind of to record the method that high-resolution moves facial image the present invention relates to a kind of intelligent camera field
And device.
Background technology
Existing technology is uniform frame per second in the recording technology that shooting motion face is used, if it is desired to recording high-resolution
Motion face is then needed using more high definition device, therefore improves the cost of equipment, and differ surely reach more high-resolution point
Resolution.
The content of the invention
Present invention solves the technical problem that a kind of method and its device for recording high-resolution motion facial image is to provide,
Motion face is shot to become apparent from.
In order to achieve the above object, the technical solution adopted in the present invention is：
It is a kind of to record the method that high-resolution moves facial image, comprise the following steps：
S1, the spatial scene of portrait that may contain motion is carried out shooting certain frame number using non-homogeneous frame per second；
S2, forward part frame number are directly exported, and remaining frame number merges the high-resolution facial image of extraction；
S3, output 1 frame normal image and some moving region topographies of 10 times of single frames resolution ratio,
After S4, the shooting that continuously happened suddenly with the speed of 10 times of conventional frame per second, intercept qualified region with optical flow method and enter
Row super-resolution composite calulation.
Further, the non-homogeneous frame per second refer to it is per second shooting 59 frames, wherein before and after preceding 49 frame two frames time interval
It it is 20 milliseconds, the time interval of two frames is 2 milliseconds before and after the 49th frame to the 59th frame.
Further, S2 is directly exported for preceding 49 frame, and the 50th frame to the 59th frame merges and extracts high-resolution facial image.
Further, S2 is output as the video flowing of 50 frames/second, and the resolution ratio of each two field picture in video flowing is all identical；
And 1 group of regional area super-resolution image of output per second, every group of amount of images be indefinite.
It is a kind of to record the device that high-resolution moves facial image, camera, cache module and arithmetic unit are included,
Using camera shooting image,
It is cached using cache module, wherein the size for caching stores 10 two field pictures enough；
Arithmetic unit detects the optical flow field of 10 two field pictures, and burst is carried out to optical flow field, only retains symbol in super-resolution image
Pre-conditioned region is closed, 10 two field pictures retain same region, constitute video in order per the corresponding region of two field picture and stand
Cube；
Arithmetic unit obtains a secondary high-definition picture with super-resolution rebuilding algorithm from each video cube body again.
Further, the shooting speed of camera can reach 500 frames/second, and camera inside is more than with storage speed
The cache module of 500 frames/second.
It is an advantage of the invention that：
The present invention compared with prior art, using and above-mentioned method for recording and device, can obtain recording higher
The motion face of resolution ratio, and reduce cost.

Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail, it should be understood that of the invention
Protection domain is not limited by specific embodiment.
Embodiment 1
It is a kind of to record the method that high-resolution moves facial image, for obtaining high-resolution motion facial image, with
The spatial scene of portrait of the specific non-homogeneous frame per second to that may contain motion shoots.The non-homogeneous frame per second refers to per second
59 frames are shot, wherein the time interval of two frames is 20 milliseconds before and after preceding 49 frame, before and after the 49th frame to the 59th frame between the time of two frames
It is divided into 2 milliseconds.
Preceding 49 frame is directly exported, and after the 50th frame to the 59th frame merges the high-resolution facial image of extraction, 1 frame of output is common
Image and some moving region topographies of 10 times of single frames resolution ratio.
Device can reach the camera of 500 frames/second comprising a shooting speed, and camera inside has storage speed big
In the cache module cache of 500 frames/second, the size of caching stores 10 two field pictures 3 enough；Arithmetic unit detects 10 two field pictures
Optical flow field 4, burst i.e. image is carried out to optical flow field, only retain super-resolution image in meet pre-conditioned region, 10 frames
Image retains same region, and video cube body 1 is constituted in order per the corresponding region of two field picture；Arithmetic unit uses oversubscription again
Resolution algorithm for reconstructing obtains a secondary high-definition picture 2 from each video cube body.
The output information of wherein record device is included:The video flowing of (1) 50 frames/second, each two field picture in video flowing
Resolution ratio is all identical；(2) the regional area super-resolution image of 1 group of output per second, every group of amount of images is indefinite.With 10 times often
The speed of rule frame per second continuously happens suddenly after shooting, and intercepting qualified region with optical flow method carries out super-resolution composite calulation
The present invention is used and above-mentioned method for recording and device, the motion people of the resolution ratio that can obtain recording higher
Face, and reduce cost.
