Abstract
The utility model relates to a computer human image distinguishing device with a built-in human image view-finding positioning scale. The utility model is at least composed of a pickup camera and a PC computer, wherein at least an image detection software, an image processing software and an image criterion software used for distinguishing human images are arranged in the PC computer, and the pickup camera (3) is installed above a display (2) of the PC computer; when the heads of people under detection face the display, the people can see own facial imaging just like looking into mirrors; a generative software of the image view-finding positioning scale is additionally arranged in the host machine of the PC computer; thorough the arrangement of the generative software, a fixed human image view-finding positioning scale can be superimposed on the display images, and the facial images of the people under detection can be aligned with the position scale through the initiative movement of the heads; thus, the computer can easily get the data of normalized facial images of which the positions and sizes are assured.
Description
Technical field
The utility model is a kind ofly to have built-in portrait and find a view the compuman of Position Scale as recognition device.
Background technology
Along with the development of technology, be widely used in the fields such as the compuman is secret in finance as recognition system, security control, gate inhibition.In prior art, general compuman does not possess the portrait Position Scale of finding a view as recognition system, the Position Scale because nobody's picture is found a view, after the image input computer system that has people's face, computer system must be concluded the accurate position of people's face and people's face size is done corresponding processing with corresponding algorithm.For example: Chinese patent application 99117360.0 " a kind of Identification of Images gate inhibition and attendance checking system ", after the image that has people's face enters this system, system at first will use polytype matching algorithm to detect people's face is arranged automatically on which position, and the accurate position of definite this people's face, system separates people's face image from background then, again this people's face image is carried out the image processing, last of size, light, expression and pose recovery, and provide the result of determination of whether " by " again with comparing in the characteristic of this people's face image and the database.Yet, in actual use, system detects and the size of any people's face is carried out restorative processing people's face image of optional position is that computerized algorithm has been proposed challenging requirement, also makes computation complexity and computing machine burden increase many simultaneously.On the contrary, system is if can obtain all fixed people's face of size and position head portrait, and the pressure that this will alleviate greatly to the follow-up identification of computerized algorithm and system makes recognition performance be able to obvious raising.
Summary of the invention
The purpose of this utility model is at the problem in the prior art, provides a kind of and has built-in portrait and find a view the compuman of Position Scale as recognition device, makes the picked-up standardization of portrait.
For achieving the above object, solution of the present utility model is as follows: it is made up of camera and a PC computing machine at least, described PC computing machine is one and wherein is provided with the PC computing machine that the Image Detection, image processing and the image that are used for Identification of Images are judged software at least that its improvement is: described camera is installed in the top of PC graphoscope; Described PC computing machine has to be established the portrait Position Scale of finding a view and generates the main frame of software in one.
By above-mentioned solution as can be seen, the utility model is arranged on camera the top of display, make the position relative fixed of camera and display, like this, when tested person's women's head-ornaments during to display, he just can see the facial imaging of oneself as looking in the mirror on display screen, for follow-up scale contraposition provides the foundation.The utility model generates software setting by the portrait Position Scale of finding a view, the fixing portrait that can on displayed image, the superpose Position Scale of finding a view, the tested person can be alignd with Position Scale by people's face image that the active of own head is moved oneself, like this, computing machine just can obtain normalized people's face pictorial data that a position and size are all determined arduously.
By above-mentioned improvement, the utility model can make the compuman simplify greatly as the detection of people's face and the handling procedure of recognition system, make the picked-up of people's face reach standardization, simultaneously, also alleviated pressure, the recognition performance of system is obviously improved follow-up image processing of compuman's face detection algorithm and system and pattern recognition.

Embodiment
Referring to Fig. 1, sequence number 1 is a cabinet, the display 2 of described PC computing machine is installed in the top of cabinet, its display panel is to the dead ahead, described camera 3 be installed in display screen directly over, when tested person's women's head-ornaments installed this, camera and display screen made the tested person can see the face's imaging of oneself as looking in the mirror just over against the face of the tested number of people.When this device work, camera 3 is sent into captured pictorial data in the main frame 4 of PC computing machine; The central processing unit of main frame is when each frame image data that camera is provided are sent to demonstration, on the assigned address of this frame image, draw a Position Scale again, like this, a Position Scale is all arranged on each shown frame image, this just is equal to the fixing Position Scale that superposeed on the image of activity, thereby has finished the generation of Position Scale.Described assigned address at each frame image is drawn the computer operation of Position Scale can be with the realization of programming of the plot statement in the Microsoft Visual C++ software.Described camera 3 can adopt the CCD camera, and maximum captured high resolution is 640 * 480 pixels, and links to each other with main frame 4 with the USB mouth; Main frame 4 can adopt the central processing unit of Pentium III, dominant frequency 500MHz; It is 1024 * 768 liquid crystal display that display 2 can use resolution.
Referring to Fig. 2, in fact the function of described Position Scale is equivalent to the view-finder in the camera, and it can be made of a positive cross wire 5 and a pair of rotational symmetry centre mark 6 that is located on this positive cross wire horizontal line.When carrying out people's face when identification, the tested person makes the eyes position of imaging overlap with centre mark 6 by moving own head, i.e. state shown in Fig. 3, and like this, system can obtain the definite people's face pictorial data of size and position.Position Scale also can be designed to other type as required, as: can be a view-finder that has centre mark, when carrying out the identification of people's face, the tested person makes the nose areas of own imaging overlap with centre mark, simultaneously, the image of oneself is fallen in the view-finder, and be full of view-finder.
