FIG. 1 is a block diagram illustrating a tracing apparatus for tracing a line using a camera according to an embodiment of the present invention. Referring to FIG. Hereinafter, the description will be made with reference to FIG. 1, and the components not shown in FIG. 1 are referred to as separate reference drawings.

According to an aspect of the present invention, there is provided a tracing apparatus using a camera, comprising a photographing unit, a discriminating unit, and a copper trace unit.

In one aspect of the present invention, the photographing unit 110 acquires an image. The photographing unit 110 may be a camera. The image capturing unit 110 acquires an image and transmits the image to a determination unit 120 to be described later. When the image conversion (distortion) occurs in the determination unit 120, the image capturing unit 110 recognizes the image as a subject (person) 130 to track the subject. The photographing unit 110 may be a general camera, a CCTV, or the like. The image photographed by the photographing unit 110 can be photographed for each frame, and each frame can be stored as separate color information, and such color information is referred to as RGB. The image photographed by the photographing unit 110 is stored in a separate storage unit so that the user can check the recorded image if desired. The information of the discrimination unit 120 and the copper trace unit 130 may also be stored in the storage unit.

The discrimination unit 120 discriminates a subject from the image acquired by the photographing unit 110. [ The subject recognizes the moving object in the image photographed by the photographing unit 110 as a subject. The determination unit 120 recognizes a subject as an object when image conversion occurs in the image. More specifically, referring to FIG. 5, an image (frame) of a previous image is compared with a current image (frame) by detecting the RGB conversion of the image, and if there is a change, the object is determined as a subject. That is, when there is a change in the RGB information of the previous image and the current RGB information, the extracted object is recognized as the subject. The discriminated subject extracts an image with an outline, gives identification information to be described later, and tracks a subject by using a tracing unit 130 to be described later.

The copper wire tracing unit 130 tracks the object determined by the judging unit 120. 2, the copper wire tracing unit 130 tracks the copper wire of the subject (person) determined by the judging unit 120 to obtain information on the subject. In other words, you can get information such as how many booths were visited in the same place in the fair or exhibition and how long they stayed there. It also has the effect of making it possible to acquire information that can be used for placing booths or exhibits at places such as fairs and exhibitions by identifying the moving lines where the subject (person) moves a lot.

The identification information gives the identification information to the object so that the discrimination unit 120 can identify the discriminated object. The identification information is given by the determination unit 120, and specifically, it is provided in at least one of character and serial number information. When the discrimination unit 120 identifies a subject, unique identification information is given to the subject, and the moving line of the subject can be continuously tracked using the discrimination information. In addition, the identification information may be provided with perceptible information. The perceptual information is identification information to be given to a subject that can not acquire facial recognition information, which will be described later, and makes it possible to separately manage facial aquisition unknown objects.

In another embodiment of the present invention, the discriminator 120 extracts the facial recognition information of the subject, and the copper tracker 130 tracks the copper of the subject from which the facial recognition information is extracted. The discrimination unit 120 extracts facial recognition information of the subject from the image acquired by the photographing unit 110 and gives identification information. This makes it possible to distinguish subjects by providing identification information classification criteria in assigning identification information to each subject. More specifically, the face recognition information is judged to be the same subject when three or more pieces of information selected from the group consisting of eyes, nose, mouth, ear and hair color of the subject coincide with each other. That is, when three or more pieces of information among the facial recognition information do not coincide with each other, they can be discriminated as different subjects. This makes it possible to distinguish the subject more accurately, thereby making it possible to more accurately extract the visit information at places such as fairs and exhibitions. Such facial recognition information can also grasp the number of times that the same subject is repeatedly visited, thereby making it possible to grasp the visitor tendency of the fair or exhibition. When used as a surveillance camera in a general building, when the subject is not a user registered in advance, the behavior can be identified as a suspicious person, and statistics can be obtained, thereby improving complementarity of the building.

4, when the discrimination unit 120 acquires the subject's face recognition information, the discrimination unit 120 recognizes the information that occupies the largest proportion among the object color, skin color, and hair color information of the subject as a main tracking target Thereby tracking the subject. That is, the copper tracker 130 tracks the moving object by using the information extracted as the main tracking object in the determining unit 120. When the facial recognition information is acquired, the discrimination unit 120 makes it possible to track the subject continuously using one of the object color, skin color, and hair color information which can be traced more simply and universally. This makes it possible to continuously track the subject when the subject is located at an angle that does not allow facial recognition of the subject. When the subject is tracked using face recognition only, the subject can be tracked using the object color, skin color, and hair color information in order to more accurately track the subject when the face is not recognizable in the face. Therefore, Even if there is no information, the object can be continuously tracked, making it possible to track the object more accurately. In the case where the object color, skin color, and hair color information of the subject are acquired, it can be displayed as an outline so that the subject can be distinguished more clearly.

In another aspect of the present invention, referring to FIG. 2, the determination unit 120 assigns identification information to a subject when a plurality of image conversions occur. This makes it possible to track each subject from an image transformation, even at places where people gather, such as fairs and exhibitions. In the case where a plurality of subjects appear at the same time, identification information is given to each of the subjects, classification information is given to the subjects that can not acquire the facial recognition information, and the facial recognition information The acquired subject can be traced by giving identification information. This makes it possible to distinguish between a face-unaware subject and a facial-recognized subject, thereby making it possible to grasp a suspicious person and make it possible to more accurately grasp the situation of the place where the line tracking device 10 is installed. The arrangement of the copper wire tracking device 10, the angle of the camera, and the like.

3, the discrimination unit 120 discriminates a subject group when a plurality of subjects move on the same copper line, gives identification information for each subject group, and counts the subject group . More specifically, moving to the same copper line grasps the same copper line with at least one piece of information selected from the group consisting of the moving direction of the subject, the moving speed, the moving time, and the distance between the objects. That is, the discrimination unit 120 can discriminate a plurality of subjects as one group and give identification information to each group to grasp the statistics of the group visitors, so that the visitor information statistics of the visitors can be more accurately and precisely .

In another aspect of the present invention, the tracer tracking apparatus 10 using a camera may be configured to include the communication unit 140. [ Two or more copper wire tracking devices 10 are provided and each copper wire tracking device 10 communicates with each other. This makes it possible to keep track of the subject by sharing the information by connecting the camera and the camera together. If the number of cameras increases, the blind spot in the building can be reduced, and the object can be tracked more effectively.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
