Wherein, described prompting figure is used for showing that the organ characteristic of the people's face on the described facial image and the applying degree of described prompting figure, described applying degree are used to indicate distance between user and the camera and the degree that aligns of user and camera.
This prompting figure can be prompting framework, prompting line segment, also can be the picture with organ characteristic's shape of people's face.The figure that prompting framework or prompting line segment can adopt the organ characteristic with people's face to match, T shape such as corresponding people's face eye feature, nose, mouth feature, it also can be cruciform, it also can be the picture of organ characteristic's shape of people's face, such as the picture of eye shape, the picture of nose shape, the picture of mouth shape etc., has certain position relationship between these eyes, nose, the mouth picture.
By these prompting figures, can show the organ characteristic of the people's face on the facial image and coincideing or the applying degree of these figures, with the distance between prompting user and the camera.For example: the face image of finding oneself as the user is less in the prompting framework, can move forward, with the distance between adjustment and the camera; And adjust the degree that aligns of self and camera, eye feature is aligned and take in the horizontal prompting framework, at least the pixel that comprises the nose feature in vertical prompting framework on the screen, the nose feature aligns and takes in vertical prompting framework, or nose feature and mouth feature align and take in vertical prompting framework, aligns and take framework until adjust to the organ characteristic of user's face.These features can be contour features, such as the profile of eyes, the profile of nose, the profile of mouth etc.
The prompting figure is other color that is different from the screen, the color of prompting figure can for arbitrary transparency greater than zero and be different from the color of described image on screen.
The user can check the organ characteristic of the people's face that shows in the prompting figure on the screen, by self move the organ characteristic that adjusts the people's face on the screen and prompting figure align degree and with the process of camera distance in, identification equipment can constantly detect facial image and identification.When the organ characteristic of people's face acquires a certain degree with the identical or applying of pointing out figure, just can effectively identify; Can also reach the highest recognition accuracy when coincideing or fit when reaching top, not only can effectively identifying.
The prompting figure can be different form, describes the detection effect of various prompting figures in detail below by embodiment.
Embodiment two
In embodiment two, the prompting figure adopts the form of prompting framework, referring to Fig. 2, may further comprise the steps:
S21: after identification equipment starts, show the facial image that camera is caught at screen;
Referring to Fig. 3, the facial image of display capture on the screen.
S22: the prompting figure that presents the organ characteristic of people's face on the described screen;
In the present embodiment, the prompting figure is the prompting framework of T shape, and on screen the fixed position at center.
The area of prompting framework is when being effective decipherment distance between people's face and the camera, and the area of the eye of described facial image, nose feature can also be the area that comprises the mouth feature.
The horizontal prompting frame body of T shape framework is for the applying degree of demonstration and people's eye feature, and vertically the prompting frame body is used for demonstration and people's nose feature and the applying degree of mouth feature for applying degree or vertical prompting frame body of demonstration and people's nose feature.
S23: identification equipment detects the distance of user and camera and aligns degree, and sends suggestion voice.
Referring to Fig. 4, owing to being used for distant apart from camera, the organ characteristic of people's face is less in the prompting framework, the identification equipment None-identified.At this moment, the user can be before the camera the mobile or voice suggestion of " please move forward " of sending according to identification equipment, adjust and camera between distance, the schematic diagram after the adjustment can be referring to Fig. 5.
Sometimes the user does not align camera, when screen imaging, situation as shown in Figure 6 can occur, and namely user's head has certain deflection, and the face feature on screen does not all show.Be presented as that user's eye feature might exceed the horizontal framework of T shape prompting framework, the nose feature has exceeded vertical framework of T shape prompting framework.Owing to the deflection of user's head, vertically go up the straight line of nose feature, mouth Characteristics creation, can be at a certain angle with vertical line shape, nose feature and/or mouth feature have exceeded vertical framework of T shape prompting framework.
At this moment the user can according to self face-image and screen on the prompting framework the degree that aligns, or " please left deflection head " that send according to identification equipment, " please's to the right deflection head " voice suggestion, adjust the degree that aligns facial and camera, make face align camera, so that facial characteristics is in the prompting framework, screen show as shown in Figure 7 to plus effect.
In this embodiment, the user is according to the distance of pointing out framework adjustment self and camera and align degree, because on screen, user's face-image in the prompting frame that shows and the deviation between the prompting frame, distinguish out from visually being very easy to, the user can slightly adjust the distance of self and camera and align degree according to the situation of screen display.
Preferably, except aligning the degree of employing voice suggestion user and camera, can also adopt the degree that aligns of character or graphical cues user and camera.Display reminding user " please left deflection head ", " please's to the right deflection head " literal for example.
The size of prompting framework can be a large amount of by statistics, the shared area of the organ characteristic of people's face on the screen when identify successfully, are optimized according to the area that counts, and the area of framework is pointed out in acquisition.
For example can determine in the following manner the framework size, through large quantitative statistics facial image, determine people's interpupillary distance between 50～70mm, preferred 60mm.According to be between user and the camera discrimination the highest apart from the time, determine the length of the pixels across point that 60mm shows at screen, and in the centre of the length of pixels across point, extend downward vertically the vertical pixel isometric with the length of pixels across point, thereby determine T shape line, distance with 40 pixel length of distance T shape line forms the T shape framework of surrounding this T shape line, and the area of this T shape framework is exactly the area of prompting framework.
Therefore, when the organ characteristic of user's face in the prompting framework, and when substantially taking framework, identification equipment just can effectively identify user's identity, take the organ characteristic of framework, the feature that may comprise whole eyes, nose, mouth also may only have eye feature and a part of nose and/or mouth feature.Voice suggestion compared to existing technology, because the user can clearly judge by the prompting figure and camera between distance and align degree, distance between rapid adjustment and the camera, align degree, be convenient to identification equipment and obtain best recognition image, thereby fast identification, shortened recognition time, recognition efficiency is high.
