The surveillance camera may include a fixed camera 110 and a movable camera 120.

The fixed camera 110 captures the constantly monitored area within the monitored area and the mobile camera 120 captures the event monitored area within the monitored area. Here, the constantly monitored area means an area to be constantly monitored in the monitoring area, and the event monitoring area means an area to be photographed when a predetermined time or an event is generated, or an area in which the appearance of the object is monitored.

The fixed camera 110 and the movable camera 120 as the surveillance cameras have a zooming and focusing function. The portable camera 120 also has a pan and tilt function to photograph moving event monitoring areas.

The portable camera 120 is provided with a PTZ controller 121 for a pan and tilt function for moving and photographing. The fixed camera 110 may also be provided with a PTZ controller.

For reference, the fixed camera 110 and the movable camera 120 may be installed independently or integrally in a single housing.

The electric sign board 130 displays information on the monitoring task. For example, in the case of illegal parking, the monitoring area displays information such as whether parking and stopping are prohibited, prohibited time, parking and stopping according to the type of vehicle.

The broadcasting equipment 140 outputs a message about the monitoring service. For example, if the monitoring area is a prohibited area, it means that the car should not be parked, the current time should be the time when the parking lot is prohibited, that the car should not be parked, It should be indicated that the driver should not drive the car, so that the surrounding area is aware that the area is a surveillance zone, and prevent the car owner from violating the car.

The alarm device 141 emits an alarm sound through an emergency bell in an emergency such as a traffic accident, an intruder or the like, and flashes the illumination through the warning light to inform the surrounding area.

When the emergency situation occurs, the emergency call equipment 143 allows a person in the field to call the relevant agency such as a police station, a hospital, a fire department, etc. to inform the emergency department.

The power supply 150 supplies power necessary for driving the surveillance cameras 110 and 120, the electric sign board 130, the broadcasting equipment 140, the alarm equipment 141, the emergency call equipment 143, and the like.

The field communication module 160 connects the fixed camera 110, the portable camera 120, the electric signboard 130, the broadcasting equipment 140, the alarm equipment 141, the emergency call equipment 143, etc. to the Internet communication network So that they can be remotely controlled through the center unit 200.

The power supply 150 and the field communication module 160 are embedded in the housing 20 so as to block the access of an outside person and to be protected from the rough external environment such as rain and snow.

The center unit 200 is connected to a plurality of field units 100 through an Internet communication network, receives and processes monitoring information from the field unit 100, and controls the field unit 100 remotely.

The center unit 200 includes a field controller 210, a DB 230, a monitoring server 220, a management server, a center communication module 240, a DLL table 250, a management server 260, an SMS server 270 An image storage server 280, an external link server 290, and the like.

The center communication module 240 is connected to the Internet communication network and performs data communication with the field communication module 160 of the field unit 100 to thereby support sending and receiving of monitoring information, remote control, and the like.

The distribution server 241 distributes the data of the on-site units received through the center communication module 240, in particular, the images captured by the surveillance cameras 110 and 120, to the corresponding devices to increase the processing speed of the monitoring task .

For example, when an image captured by the surveillance cameras 110 and 120 is received by the center communication module 240, the received image is distributed to the image storage server 280 and the monitoring server 22 and transmitted.

Since the center unit 200 manages the various on-site units 100, the distribution server 241 analyzes the data received via the center communication module 240 (e.g., how many times the image of the on- ) And distribute it to the corresponding equipment so that the surveillance service is not delayed or overloaded.

The field controller 210 controls the driving of the fixed camera 110, the portable camera 120, the electric sign board 130, and the broadcasting equipment 140 by the field unit 100.

The field controller 210 includes a plurality of field controllers 210A for controlling the driving of the respective field units and a manager unit 210B for managing the field controllers 210A.

The field controller 210 of the present invention has 64 field controllers 210A and one manager 210B for controlling the field controllers 210A to control the 64 field units 100. [

The field controller 210A of the field controller 210

A camera control module 211 for controlling operations of the surveillance camera high fixed type camera 110 and the movable type camera 120 such as panning, tilting, zooming and focusing,

An object recognition unit 214A for recognizing an object in an image captured by the surveillance camera cameras 110 and 120 and an object tracking unit 214B for tracking the movement of the object recognized by the object recognition unit 214A An object analysis module 214,

A broadcast equipment control module 213 for controlling the operation of the volume, tones, etc. of the sound output from the speaker,

An intermittent mode algorithm module 215 for generating a command signal in accordance with the set intermittent mode and transmitting the generated command signal to the camera control module 211 and the object analysis module 214 to perform intermittent intermittent driving by the camera,

And an intermittent schedule management module 216 for registering and managing information on the intermittent schedules of the surveillance cameras 110 and 120.

The intermittent mode of the intermittent mode algorithm module 215 includes a manual intermittent mode, a semi-automatic intermittent mode, and an automatic intermittent mode, as shown in FIG.

In the manual intermittent mode, pan, tilt, zoom, focusing, shooting, etc. of the surveillance cameras 110 and 120 are controlled in accordance with an operation signal inputted by an administrator through the monitoring server 220, .

In the semi-automatic intermittent mode, when the fixed camera or the movable type cameras 110 and 120 photograph license plate numbers of vehicles parked on the road in accordance with an operation signal inputted by the manager through the monitoring server 220, The movable type camera 120 automatically takes a picture by the set program.

The automatic intermittent mode is a mode in which the camera or the portable camera 110 or 120 is panned, tilted, zoomed, or rotated in a predetermined time according to a preset program, a specific event is generated, Focusing and shooting are automatically controlled to automatically shoot the background and license plate of the vehicle.

In the automatic intermittent mode, the background of the vehicle and the license plate can be photographed by the touring method, the wide zone method, and the object method.

The touring method is a method in which a plurality of intercepting points are registered in the monitoring area and the moving camera 120 photographs the intercepting points sequentially while moving. In this way, the recognition rate is good, but the interception speed of the driving vehicle is slow, If there is illegal driving on the non-driving area, there is a disadvantage that it can not be regulated.

When the presence of a vehicle is recognized while the fixed camera 110 or the portable camera 120 captures and monitors a wide area of the constantly monitored area, the wide area zone system simultaneously recognizes a plurality of vehicle numbers in the image, Or by photographing the background and license plate of the recognized vehicles using the zooming and focusing of the portable camera 120, it is possible to fasten the speeding-up speed of the vehicle,

In the object mode, when the fixed camera 110 recognizes that the vehicle enters the normal monitoring area, the portable camera 120 adjusts the pan, tilt zoom, and the like to photograph the license plate and the background of the vehicle. It is also possible to control the vehicle in the middle of running or tail.

The object analysis module 214 includes an object recognition unit 214A for recognizing an object appearing in the image by analyzing an image captured by the surveillance cameras 110 and 120 and an object tracking unit for tracking the movement of the recognized object 214B.

The object analysis module 214 has functions of object recognition, object tracking, object counting, number recognition and object enlargement, and function of judging object disappearance, object appearance, virtual line intrusion, roaming,

As shown in FIG. 6A, the object recognition unit 214A recognizes and tracks an object in an image through an image preprocessing process, an object extraction process, an object classification process, and an object tracking process.

The image preprocessing process includes a background extracting process for extracting a background from an image through a background update, a motion region extracting process for extracting a corresponding image portion by determining an area where a motion is generated using a pixel difference between a background average image and a current image as an object, And a noise removing process for removing the noise from the camera image to clarify the object area.

The object extraction process includes an object blocking process for generalizing the object region generated by the image preprocessing process to a rectangular region, an object grouping process for grouping object blocks extracted in the blocking process to a neighboring block, And a shadow removal process.

The object classification process classifies the objects through pattern matching of the learned data with respect to the objects extracted in the object extraction process.

In the background extraction process, a camera image is captured for a certain period of time, an average of accumulated image frames is taken to generate a background image, and a fixed image without change of the image is extracted as a background through continuous updating.

The motion region extraction process uses the pixel difference between the background average image and the current image obtained through the background extraction to determine the image of the region where the motion occurs as an object, and extracts the corresponding image portion as an object region.

The noise removal process uses a morphology technique to extract an accurate object region by removing irregular noise when extracting a background from a camera image. The morphology technique is an image processing technique used to transform the shape of a specific object existing in the image, and is mainly used in binary image processing.

The morphology technique uses a 3 * 3 mask to scan the entire image as a mask, and removes noise by applying an erosion / expansion algorithm to the pixels determined to be noise through correlation between the center pixel and surrounding pixels.

Erosion algorithm that removes noise by eliminating thin protruding part of object outline and smoothens outline of object, and erosion and expansion through an expansion algorithm that performs the process of making object's outline clear by filling the outline of object outline And extracts an accurate object region by removing irregular noise that affects object recognition performance.

6B shows an image before and after the noise removal process.

In the object extraction process, the blocking process and the object grouping process are performed on the object region of the object motion image (binary image) generated through the image preprocessing process.

Object blocking is a generalization of an object area generated by an image preprocessing process to a rectangular area and includes basic information (end point, object width, object height) in the area. FIG. 6C shows an example of an image before and after object blocking.

Object grouping is a grouping process for neighboring blocks to accurately extract objects that are not precisely classified into object information extracted in the blocking process. In the grouping process, if the distance between the specific block and the neighboring block is less than a certain distance, it is determined that the same object region is shared and reconstructed into a single block. FIG.

The object classification process determines whether a specific object (person, vehicle, or the like) to be searched through pattern comparison between the image of the grouped object region and the learned data. If the object is determined as a specific object, the tracking function is applied. The learning training technique used in the object classification process extracts specific patterns (features) from the object image to be recognized.

The learning training technique is a technique for extracting characteristics (similarity degree of image pixels with respect to a certain pattern) data for a large number of specific object images and recognizing an object to be searched through pattern matching of learned data in a real time image . The more the training training is repeated, the higher the recognition accuracy of the object.

The shadow removal process is applied to remove unnecessary data due to the shadow region in object extraction. The luminance component of the color image is extracted from the grouped object block to extract the shadow region, and the luminance of the generated shadow region The value is approximated to the luminance value of the entire image to remove the shadow region. Through the shadow removal process, the shadow image around the object is removed to improve the recognition rate by clearly distinguishing the object and the background.

The object recognition module of the object analysis module recognizes the object by applying the above-mentioned learning training technique. In this case, since the image data of the upper human body region is extracted and recognized, It provides high recognition rate.

The object tracking unit 214B extracts coordinates of an object of the object recognized by the object recognizing unit 214A, analyzes the change of coordinates, predicts a moving direction and a moving distance, and calculates a moving direction and a moving distance The object tracking process is performed by the surveillance cameras 110 and 120 so that the object is positioned at the center of the image.

The object tracking process divides the target area into cells of a certain size by analyzing the pattern of the recognized object, obtains a distribution map of the direction of the edge pixels for each cell, . 6E is an example of dividing the object into cells for tracking and obtaining the distribution.

The intermittent schedule management module 216 registers information on the intermittent schedule such as the timing, condition, and method of intermittent control, and transmits the intermittent schedule information to the surveillance cameras 110 and 120, the electric sign board 130, Thereby allowing the field controller 210 to control the driving of the equipment 140.

Examples of illegal parking regulations include the designation of the regular monitoring area and the event monitoring area, the timing of permitting a parking permit, the permission of a parking permit depending on the vehicle, whether or not it will be interrupted after a certain period of time (eg 10 minutes) A zone zone method, and an object method in the automatic intermittent mode according to the control schedule information.

The manager unit 210B includes a communication unit 217, a management unit 218, a car number recognition module 219, and the like.

The communication unit 217 communicates data such as monitoring information and operation signals with the monitoring server 220.

The management unit 218 controls the camera control module 211, the electric sign board control module 212, the intermittent mode algorithm module 215 and the like and transmits the operation signal of the monitoring server 220 received through the communication unit 217 And transmits it to the corresponding part (for example, the camera control module 211, the object analysis module 214, or the like), and checks whether the field control unit 210A operates normally.

The car number recognition module 219 recognizes the car number from the image captured by the surveillance cameras 110 and 120 and extracts the image in which the car number is recognized with the still cut together with the information necessary for shooting time and other intermittence, And stores it in the DB 230 as monitoring information.

The car number recognition module 219 extracts a car number-expressing image as a snapshot and stores it as monitoring information in a DB. Here, the snapshot refers to a frame in which a car number is displayed among frames (still images) constituting a moving picture to be photographed by a camera.

FIG. 7 shows image data according to the process of extracting the car number by the car number recognition module 219.

Referring to FIG. 7, the car number may be extracted by converting the original image into a gray image, a gray image by Sobel filtering, Dog filtering, Laplacian filtering, filtering masks for masking areas irrelevant to the license plate in the filtered image, It is possible to detect potential candidate regions, to detect candidate plates, and to extract the number from the detected candidate plate.

The surveillance cameras 110 and 120 capture the background image and the car number image of the vehicle by controlling the field controller 210 and extract the captured background image and the car number image and store them in the DB 230, The vehicle number recognition module 219 of the field controller 210 also stores the image of the vehicle number in the DB 230 and transmits the image to the monitoring server 220 Minimize the monitoring work even if a problem occurs.

The surveillance work should continue without interruption even if there is no special operation by the administrator.
