Detailed description of the invention
For making the purpose of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment. Should be appreciated that specific embodiment described herein is used only for explaining the present invention, be not intended to limit the present invention.
The invention provides a kind of camera control method based on eye feature identification, as it is shown in figure 1, comprise the steps:
S1, pre-build eye feature and the one-to-one relationship taking pictures between control instruction, and store.
In order to the change realized according to eyes of user realizes the control of taking pictures to terminal, firstly the need of prestoring an eye feature and the one-to-one relationship table taken pictures between control instruction in the terminal, by the identification to user's eye feature, comparison goes out the control instruction of taking pictures that active user sends, and operates accordingly thus controlling terminal according to this control instruction of taking pictures.
Concrete, in conjunction with eye feature schematic diagram shown in Fig. 2, described eye feature is: eye socket profile width, the black pupil of eyes 21 are in intra position and with or without black pupil 21.
The one-to-one relationship of described eye feature and control instruction of taking pictures is:
Eye frame profile width differs in preset range with predetermined orbital width, and current black pupil is positioned at a frame centre position, then control instruction of taking pictures is that camera initializes;
Eye frame profile width is more than predetermined orbital width, and both differences are beyond preset range, and black pupil is positioned at a frame centre position simultaneously, then control instruction of taking pictures is that image amplifies;
Eye frame profile width is more than predetermined orbital width, and both differences are beyond preset range, and to be positioned at a frame centre position on the upper side for black pupil simultaneously, then control instruction of taking pictures is for upwards to focus;
Eye frame profile width is less than predetermined orbital width, and both differences are beyond preset range, and to be positioned at a frame centre position on the lower side for black pupil simultaneously, then control instruction of taking pictures is focusing downwards;
Eye frame profile width differs in preset range with predetermined orbital width, and current black pupil to be positioned at a frame centre position to the left, then control instruction of taking pictures is for focus to the left;
Eye frame profile width differs in preset range with predetermined orbital width, and current black pupil to be positioned at a frame centre position to the right, then control instruction of taking pictures is for focus to the right;
Eye frame profile width is less than predetermined orbital width, and both differences are beyond preset range, and current black pupil is positioned at a frame centre position, then control instruction of taking pictures is that picture reduces;
Eye frame profile width is less than predetermined orbital width, and both differences are beyond preset range, and can't detect black pupil, then control instruction of taking pictures, for closing camera, even can't detect black pupil, then the eyes that explanation user is current are in closure state.
Can be seen that from above-mentioned corresponding relation, the difference of eye feature, corresponding different control instructions of taking pictures, and need in the terminal to prestore a human eye orbital width under normal circumstances as predetermined orbital width, and preset a scope, when the orbital width of detection is in scope set in advance, then think that the current eyes of user are under normal situation, if beyond this scope set in advance, then respectively according to the intra position of current eye width of frame and black pupil place, the comparison of control instruction of taking pictures accordingly.
Above-mentioned terminal can be mobile terminal, such as mobile phone, Intelligent worn device or panel computer etc., it is also possible to computer or other for fixed placement are fixedly installed other smart machines with camera function.
S2, obtained facial image by photographic head, and from described facial image, identify current eye feature.
Photo terminal can pass through arrange camera and a range sensor is connected, when range sensor monitors and has object to occur in preset distance, then trigger camera to boot up, obtain objects in front image, to whether it is that face is identified, if eye feature is identified by face further.
Concrete, in order to realize the accurate identification to eye feature, described step S2 includes:
S21, obtaining facial image every the scheduled time, whether eye width of frame and black pupil are changed in intra position is identified, if changing, then performs step S22;
S22, calculate the difference of eye socket profile width and predetermined orbital width, and obtain current black pupil and be in intra positional information, and store.
Owing in the process of taking pictures, user is likely to send in the process of taking pictures control instruction of taking pictures, therefore camera is every the scheduled time, just whether the eye feature of user is changed and be identified, and the information that will identify that is sent to control module and operates control accordingly.
Control instruction of taking pictures corresponding to the eye feature that S3, basis identify controls camera and operates accordingly. Concrete, according to the eye feature detection case preset in step S1, corresponding control instruction of taking pictures of searching, and control operation accordingly according to the control instruction of taking pictures found out.
Include after described step S3:
S4, when detect camera perform close camera take pictures control instruction time, in delete step B obtain facial image, and storage eye feature information.
Due in above-mentioned steps camera by facial image is identified, and this facial image is just no longer necessary to after this secondary control operates, and substantial amounts of facial image committed memory, therefore while this camera shuts down, the human face image information got in process that this camera is taken pictures and the data message being calculated when carrying out eye feature identification etc., all carry out delete processing, it is to avoid the problems such as eye feature acquisition of information mistake or the phase engine efficiency reduction that causes due to EMS memory occupation occur.
Specific embodiment in this way is that the present invention is described further for example below, as shown in Figure 3:
H201, opening photographing unit, be that camera initializes according to control instruction corresponding under the pre-set normal state of eyes, user, with normal eye alignment cameras photographic head, sends the initialized control instruction of taking pictures of camera.
H202, detection eyes of user change relatively normally: by the situation of change of eyes of user, each frame detected all can write logging modle.
Each frame that H203, record eyes of user change, for judging and situation of change under normal circumstances, thus opening corresponding event handling. When automatically emptying after end of taking pictures, in order to do not affect taking pictures next time.
H204, shooting control instruction to above-mentioned steps H203 respond, and as eyes normally diminish relatively, drawing reduces.
H205, take pictures when completing this time after eyes closed. Can set that repeatedly Guan Bi is taken pictures and camera function simultaneously.
H206, this time take pictures complete.
Based on the above method, invention additionally discloses a kind of control terminal of taking pictures based on eye feature identification, as shown in Figure 4, including:
