You can take immediate action on any incident on the platform and train. Accordingly, the present invention relates to a train emergency control system and method using a video incident detector that enables train operators, station attendants, situation controllers and passengers to cope quickly with an accident situation.

The current train (train / subway) platform is marked with a safety line indicating the distance that the passenger should be separated from the vehicle until the vehicle has entered or departed. Safety lines are marked on the outside of the platform at regular intervals from the track to prevent passengers waiting for the vehicle from being swept or hit by passing, entering or departing tracks and inadvertently colliding with vehicles entering the platform tracks. Access control line.

Accordingly, passengers protect themselves from vehicles entering at high speed by adhering to the safety line at the time of entry and departure of the vehicle, and evacuate safely into the safety line at the time of vehicle entry or departure by horn sound and guidance broadcasting of the vehicle.

The description of the basic structure and operation of the image detection detector 100 applied to the present invention is the same as the 'subway / railway platform accident detection automatic image processing alarm system and method' filed by the applicant, the same description Instead.

The image distribution device 120 applies an operation control signal of the imaging device 20 to be transmitted to the imaging device 20 based on a result of analyzing the image by the sensing module of the image processing device 140. The image pickup device 20 receives the captured image and transmits the captured image signal to each component that processes the captured image signal, such as a station office, a central command room, an image conversion device 130, and an image splitting device 110. In this case, the image distribution device 120 amplifies the captured video signal received from the image pickup device 20 to faithfully adhere to the original video video signal and transmits it to the office, the central command room, and each component.

It automatically detects the situation, and when the accident occurs, immediately generates an alarm signal including the image signal information in which the accident occurred.

Extraction of the sensed information using the image processing according to the present invention can be largely divided into a method using a tripline and a tracking method for tracking the movement of the moving object.

First, in the case of the tripline algorithm, a tripline is generally installed at the center of the area to be monitored in the image, and the gray level between the reference image and the current surveillance area image is in the installed tripline area. The occupancy information is calculated by analyzing the difference or the change in the feature value. This method only handles a given region, so the computation is small and the algorithm is relatively complex.

The information resulting from the tripline detection algorithm is primarily information on the presence or absence of a sensing target. Using this information, the size of the sensing target can be directly obtained and the two triplines are used to detect the size. The amount of displacement of the target can be obtained. However, since this method can only know the movement of the moving object at a predetermined position, it is difficult to obtain accurate information due to the change inducing factors such as environmental factors. However, this method plays an important role in providing trigger information that informs when the target is tracked in the tracking method for tracking the movement of the sensing target. Therefore, the algorithm of this stage must have good performance to perform good performance in the tracking stage of the sensing target. Can make

Second, the tracking algorithm that tracks the motion of the sensing object separates the area of the sensing object from the background, obtains the necessary information by predicting the movement direction of the area of each object, and predicts the position in the next image. The detection object is tracked in an arbitrary direction. By using this method, information on the movement of the sensing object can be obtained, so that more accurate occupation information can be obtained than the tripline, and information on the change in the direction of movement of the sensing object or the movement of the monitoring area can be extracted. However, when images of a plurality of sensing targets overlap during tracking of a sensing target, a problem occurs in that only one sensing target is visible in the image, thereby causing a problem of losing the sensing target during tracking of the sensing target. Therefore, in order to solve the problem of overlapping two sensing objects, it is necessary to distinguish and recognize the areas of each sensing object.

Therefore, the tracking method of the sensing object requires the process of separating the sensing object from the sensing object area, the process of recognizing the sensing object, and the process of predicting the recognized area. It requires a powerful computing system.

Accordingly, the image processing apparatus 140 is provided with a sensing module to install a trip line in the center of the area to be monitored in the landing image, and the reference image and the monitoring in the area of the trip line installed A tripline algorithm that determines whether a sensing object exists by comparing and analyzing the change of gray level of the region image, and after separating the region of the sensing object from the background in the reference image, movement of the region occupied by each sensing object A multi- algorithm operation is performed by combining a tracking method algorithm for obtaining a direction and determining a movement state of the sensing object determined by the tripline method algorithm.

By receiving, you experience a three-dimensional alarm system.

The image splitting unit 110 divides the image signal in accordance with the monitor screen so that a plurality of image signals photographed from the image capturing apparatus 20 can be integrated and displayed on one monitor, and the alarm control device 150 According to the alarm control signal (S2) from the predetermined divided video signal to select the video signal in which the sudden situation occurs, the image segmentation is released so that it can be enlarged and displayed on the monitor.

That is, the plurality of video signals photographed from the imaging device 20 are displayed in multiple by dividing one monitor screen, and the video signal in which the abrupt situation occurs among the plurality of video signals photographed from the imaging device 20 is The monitor screen is displayed in its entirety without being divided so that it can be immediately identified.
