Description

Ultra-thin contact-free WYSIWYG intelligent image acquisition equipment and acquisition method

Technical Field

The invention relates to an ultra-light thin contact-free WYSIWYG (what you see is what you get) intelligent image acquisition device and an acquisition method, and belongs to the field of data acquisition devices.

Background

With the rapid development of modern information technology, more and more self-service devices come into the market, wherein self-service photographing devices are also greatly emerged. Traditional self-service equipment of shooing generally includes camera and display screen, and the user looks at camera, manual button control camera and shoots, recycles the preview effect image that the display screen preview was caught in real time, reaches the purpose of autodyning.

The existing self-service photographing equipment mainly has the following core problems:

1. what you see is what you get is not really achieved.

Because the camera generally sets up in the frame department or the frame of equipment display screen outside, when shooing, if the user looks at the preview effect of display screen and shoots, eyes do not aim at the camera naturally, and the photograph of shooing often can appear looking at the miraculous unnatural condition such as strabismus, the eye is improper. If the user looks at the camera and shoots, the preview effect and the prompt message of the screen can be ignored, and the shooting quality and the user experience are not ideal. In addition, the traditional self-service equipment is used for taking a picture, and two steps of determining a picture and starting a key to take a picture are required. Compared with the moment that the user really wants to take the picture and the moment that the self-service photographing device actually takes the picture, a certain delay usually exists, the shooting effect of the self-service photographing device is seriously affected by the existence of the delay time, and when the device starts to take the picture, the picture determined by the user disappears, so that the self-photographing picture really wanted by the user is difficult to take. The user can not compromise camera and display screen simultaneously when using self-service equipment of shooing, and there is the delay condition in shooing moreover, and the photo that leads to seeing is different with the photo of shooing out, can not realize seeing promptly to obtain, and the one-tenth qualification rate is lower, and the user experience of shooing is poor.

2. The equipment is large in size and the application scene is limited.

For example, chinese patent application No. CN201810147248.9 discloses a touch-free intelligent self-service license photographing apparatus and method, the apparatus includes a case, an input/output module, a photographing module and an intelligent module, one side facing the photographing area is provided with a unidirectional perspective glass, a closed space formed by the unidirectional perspective glass enables a user to see the effect of a full mirror when looking at the photographing module, and the user can see the self-expression in real time and correct the self-expression in time like looking at a mirror when photographing. But this shooting equipment has the global design of similar cabin, because factor limitations such as keying technique and photo processing technique need be equipped with the convenient later stage keying of pure color's background board in addition and handle, and in order to build the environment of shooing of suitable luminance, need carry out multi-angle cloth light around equipment for equipment is whole to occupy fairly big space resources (highly be higher than human height, width and thickness all are on 50 centimetres), and equipment is heavy, inconvenient transport and installation, and application scene is restricted.

3. Shooting interaction is complex, and users are troublesome to use.

For example, chinese utility model patent document No. cn202022357771.x discloses a cabinet type mirror touch type photographing apparatus, which includes an apparatus box, a photographic paper printing device, a mirror display module, and a photographing module. The device plays the effect of mirror to the person of shooing through setting up mirror surface subassembly. But the user still needs to touch during operation, and the risk of cross infection is likely to exist. Thirdly, the camera position cannot be automatically adjusted, the user needs to adjust the height to adapt to the equipment, and real intellectualization is not realized.

4. The existing self-service photographing equipment has other problems, for example, in order to better extract a portrait from a picture for image matting and beautifying in the later period, a user needs to finish photographing in a pure background; for example, the requirement on the photographing light is high, and a picture with good quality cannot be taken in a brighter or darker environment; the above are all due to the defects of the acquisition processing method, which results in higher requirements on the application environment of the equipment, and the use scene of the equipment is limited to a certain extent; for example, the device fixing mode is single, only a single installation mode can be supported, and the device can be placed on a desktop or installed in a pavilion and cannot adapt to more application scenes; for another example, the security is weak, and real-time monitoring and feedback on the damage activities occurring on the self-service photographing device are difficult to achieve. These are all because of the defects of the self-service device structure function, which leads to the limited use scene of the device.
