Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The application scenarios that the embodiment of the present invention is mentioned can be as shown in Figure 4, when user utilizes terminal to carry out non-hand-hold type auto heterodyne, within the scope of distance terminal certain distance, is taken pictures by limb action control terminal.
Fig. 1 is the schematic flow sheet of the method that a kind of triggering that the embodiment of the present invention provides is taken pictures, and as shown in the figure, the method that described triggering is taken pictures can comprise:
S101, obtains the picture frame that camera imaging obtains.
Concrete, the limb action receiving user's input controls the request of taking pictures, and starts camera, obtains the picture frame that camera imaging obtains.Above-mentioned camera can be the smart mobile phone (as Android phone, iOS mobile phone etc.) with camera function camera, there is the camera of the panel computer of camera function or there is the first-class camera with limb action recognition function of shooting of Intelligent worn device of camera function.Above-mentioned limb action recognition function can be realized by action recognition technology existing in prior art, such as, user is when entering in camera image pickup scope, motion sensor is that the human body image of user sets up a human digit skeleton, and the artis chosen in human digit skeleton, any limb action of user is all identified by the movement of artis in motion sensor determination and analysis human body image.This step continues to carry out until described camera terminates after being taken pictures by control.
S102, identifies the human body target region in described picture frame.
Concrete, by image processing techniques by the human body target region recognition in the picture frame that obtains in step S101 out, above-mentioned human body target region can be one, also can be multiple.The identification in described human body target region is realized by background subtraction method of the prior art, fast matching method, the light stream estimation technique, images match method, global motion estimation algorithm etc.Such as, the image averaging value of picture frame in preset time period can be obtained, this image averaging value can be used as reference picture, picture frame and reference picture are carried out difference operation, what difference was larger is defined as doubtful human body target region, determines human body target region in conjunction with human figure feature from doubtful human body target region.
Optionally, from the human body target region identified, filter out the human body target region that size is greater than region threshold, ignore the human body target region that distance terminal camera presents apart from excessive human body in picture frame.
S103, obtains the sample limb action image of taking pictures preset.
Above-mentioned default sample limb action image of taking pictures can be the image of any human body limb action, such as, kick, shake the head, nod, wave arm, jump etc., and the image of a kind of human body limb action of chosen in advance is as sample limb action image of taking pictures.
S104, judges whether comprise the image-region with described sample limb action images match of taking pictures in described human body target region, if so, then performs step S105; Otherwise, perform step 106.
S105, obtains the time delay of taking pictures preset, and controls camera take pictures when described time delay of taking pictures is arrived at.
S106, does not process.
In specific implementation, whether the human body target region identified in determining step S102 comprises the image-region with described sample limb action images match of taking pictures.Such as, the feature of the artis of sample limb action image in human digit skeleton of taking pictures that can be obtained by analytical procedure S103, whether the artis in the human digit skeleton in the human body target region identified in determining step S102 comprises the feature of the artis of sample limb action image in human digit skeleton of taking pictures.If so, then perform step S105, if not, then perform step S106 and do not process.The judgement of the image-region of sample limb action images match of taking pictures described in can being realized by the Algorithm Analysis etc. based on action sequence of the prior art.
Optionally, obtain the matching times of described human body target region and described sample limb action images match of taking pictures, when described matching times is more than or equal to frequency threshold value, be judged to comprise.Concrete, detect in described human body target region comprise with the image-region of described sample limb action images match of taking pictures after preset time period in, obtain the matching times of human body target region and described sample limb action images match of taking pictures described in picture frame, when described matching times is more than or equal to frequency threshold value, be judged in described human body target region, to comprise the image-region with described sample limb action images match of taking pictures, when described matching times is less than frequency threshold value, be judged in described human body target region, not comprise the image-region with described sample limb action images match of taking pictures.The above-mentioned default time period is a period of time that duration is less than in step S105 delay duration of taking pictures.
Preset from detect human body target region comprise and described sample limb action images match image-region to control camera take pictures time delay of taking pictures, when step S104 judges to comprise the image-region with described sample limb action images match of taking pictures in described human body target region, start-up study module carries out timing, takes pictures when controlling camera when described time delay of taking pictures is arrived at.
The embodiment of the present invention, by the human body target region in recognition image frame, determines to comprise in described human body target region the image-region with sample limb action images match of taking pictures, and then control camera is taken pictures when the time delay of taking pictures preset is arrived at.Achieve the sample limb action image of taking pictures by identifying user, and then control camera is taken pictures, and improves the convenience of operation.
Fig. 2 is the schematic flow sheet of the method that a kind of triggering that another embodiment of the present invention provides is taken pictures, and as shown in the figure, described method can comprise:
S201, obtains the picture frame that camera imaging obtains.
Concrete, the limb action receiving user's input controls the request of taking pictures, and starts camera, obtains the picture frame that camera imaging obtains.Above-mentioned camera can be the smart mobile phone (as Android phone, iOS mobile phone etc.) with camera function camera, there is the camera of the panel computer of camera function or there is the first-class camera with limb action recognition function of shooting of Intelligent worn device of camera function.Above-mentioned limb action recognition function can be by prior art after action recognition technology, such as, user is when entering in camera image pickup scope, motion sensor is that the human body image of user sets up a human digit skeleton, and the artis chosen in human digit skeleton, any limb action of user is all identified by the movement of artis in motion sensor determination and analysis human body image.This step continues to carry out until described camera terminates after being taken pictures by control.
