Description

System and Method for Tracking and Monitering a Moving Object

The present invention relates to a moving object tracking and monitoring system and a method and a computer readable recording medium recording a program for realizing the method. More particularly, the present invention relates to moving a target moving object captured by a camera. A system and a method and a method for enabling a plurality of cameras to track and monitor the moving object even without the user's control by automatically capturing the moving object by a camera adjacent to the coverage area to which the moving object currently belongs, even if it is out of coverage. The present invention relates to a computer-readable recording medium having recorded thereon a program.

In general, in a space where a plurality of cameras are installed, the target moving object is sequentially monitored on the plurality of camera images with a time difference according to the movement thereof. At this time, the user needs to track the movement of the target moving object and be provided with an image as if viewed with one camera.

As a related art related to a method of monitoring a movement of a moving object using a plurality of cameras, there is a method of controlling a camera using a pen tilt camera to monitor the movement of the moving object in a region where a plurality of cameras are installed. However, such a method has a limitation in camera coverage in the up, down, left, and right directions so that the movement of the moving object may not be tracked or monitored when the camera is out of coverage.

In another conventional technology, after installing a plurality of cameras, a button for viewing an image provided by each camera is set in a user interface so that each time a button is selected, a corresponding camera image is provided to track and monitor a moving object. There is a method that can be used, and another conventional technique is a method used for security or surveillance for providing a divided screen on the user interface so that the user can simultaneously view the images provided by the plurality of cameras.

However, these prior arts have a problem that the user has to check the position of the moving body directly because the plurality of fixed cameras simply provide the image in the coverage without tracking the moving object, and the user has to check the provided image of the camera individually. There is a problem that the user is inconvenient to use.

The present invention has been proposed to solve the above problems, and even if the target moving object captured by one camera moves out of the coverage of the camera, the adjacent camera of the coverage to which the moving object currently belongs automatically captures the moving object. It is an object of the present invention to provide a system capable of tracking and monitoring a moving object by a plurality of cameras without control, and a method and a computer-readable recording medium recording a program for realizing the method.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a detailed configuration of an embodiment of a moving object tracking and monitoring system according to the present invention.

As shown in FIG. 1, the system according to the present invention includes an image for transmitting image information captured by a plurality of cameras 121 to 123 installed in the region of interest 140 to the image providing server 110 through the Internet. An information DB (120), an image providing server (110) for providing the acquired images to the user terminals (131 to 133), and an image DB for storing the acquired image in association with the image providing server (110); 111 and user terminals 131 to 133 for receiving the acquired image, and a sensor is attached to each moving object to acquire an image in the region of interest 140. On the other hand, the image providing server 110 is a moving object list device 111 for detecting and listing the moving object attached to the sensor, the sensor detection device 112 for distinguishing the moving object by separating the sensor attached to the moving object from the server The apparatus includes a moving object detecting apparatus 113 for searching for a moving object on the acquired image, and an image providing apparatus 114 for providing a camera image using compression and reconstruction.

The principle of the tracking and monitoring method of the moving object according to the present invention is as follows.

When a plurality of cameras are installed, each of the cameras are adjacent to each other, and if the moving object is missing from the image provided will move to the image of the adjacent camera. Therefore, if the moving object disappears by giving priority to the adjacent cameras, the moving object should be searched for in the adjacent cameras to provide a camera image including the moving object. At this time, the priority of the adjacent cameras may be given arbitrarily or automatically, and one embodiment of a method of automatically giving priority to the adjacent cameras is as follows.

As shown in Fig. 1, if cameras A, B, and C are in order, the adjacent cameras of camera A are cameras B, and the adjacent cameras of camera B are cameras A and C. In addition, the adjacent camera of camera C becomes camera B. FIG. On the other hand, since the adjacent cameras of the camera B are camera A and camera C, priority is given to any one of the two cameras. Table 1 shows an embodiment of automatically assigning priorities to adjacent cameras for each camera.

division 1st order adjacent camera 2nd order adjacent camera 3rd order adjacent camera Camera A B Camera B A C Camera C B

Looking at an embodiment for tracking the movement of the moving object in accordance with the priority in Table 1 as follows.

If the moving object disappears from camera A, the camera B is searched for the first neighbor. If there is a moving object in camera B, the image of camera B is provided to the user. However, since Camera A has already searched, it searches for Camera C, which is a second-order neighbor. In this way, the camera containing the target image is found and the user image is changed.

Figure 2 is a detailed flowchart of an embodiment of a moving object tracking and monitoring method according to the present invention. An embodiment of a moving object tracking and monitoring method will be described in detail below with reference to FIG. 2.

First, when the moving object list apparatus creates a moving object list for moving objects retrieved from images acquired by a plurality of cameras, a user selects a moving object (hereinafter, referred to as a 'target moving object') to receive an image from the created moving object list. (201). When the target moving object is selected, a default camera for the selected target moving object is driven (202). At this time, the default camera may be the camera including the target moving object as the default camera when the moving object list is created, or may arbitrarily set the default camera for each moving object.

On the other hand, when the target moving object disappears from the camera image according to the movement of the target moving object, at this time, the movement of the target moving object should be tracked to provide an image of the camera including the target moving object. Accordingly, the moving object detecting apparatus searches for whether the target moving object exists in the image of the driven camera (203), and if the target moving object does not exist again, searches for the target moving object in the images of the camera and the adjacent camera according to the priority of the camera. (204) In addition, if the target mobile object is present in the image of the camera as a result of the search, the image providing device provides the image of the camera through a network such as the Internet (206). Repeat.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, according to the present invention, the camera automatically tracks and monitors the target moving object according to the movement of the target moving object, so that the target moving object can be monitored without a user's separate operation. There is an effect that can be provided.
