Description

System for smart traffic lights with camera}

It relates to a traffic light system that outputs a vehicle signal or a walking signal, and more specifically, a smart camera equipped with a camera for recognizing a vehicle number to detect a signal violation vehicle by capturing a traffic light and a vehicle and recognize the vehicle number of the vehicle that violates the signal. It is about a traffic light system.

In general, pedestrian traffic lights are installed on pedestrian crossings so that pedestrians can cross the pedestrian crossing safely, and vehicle traffic lights are installed to control the passage of vehicles in connection with pedestrian traffic lights.

At this time, when the vehicle traffic light turns on the yellow light, it is prohibited to enter the crosswalk of the vehicle, and when the vehicle traffic light turns on the red light, the vehicle must stop outside the stop line.

4 is a view illustrating the operating characteristics of a smart traffic light system according to a first embodiment of the present invention.

In the smart traffic light system according to the present embodiment, when the first signal output unit 100 outputs a vehicle signal or a pedestrian signal for a pedestrian crossing installed on a road or an intersection of two or more lanes (S405), the first photographing unit 200- 1) The first video for the first signal output unit 100-2 installed in the opposite lane and the second video for the area including the stop line of the pedestrian crossing are respectively photographed (S410) and the controller 300 May receive information about a vehicle signal or a walking signal output from the first signal output unit 100 (S415).

When the first video and the second video are respectively photographed, the controller 300 displays video information including an image in which a vehicle signal or a pedestrian signal for a pedestrian crossing is output among a plurality of frames constituting the first video at predetermined time intervals. By extracting (S420), the vehicle signal or the walking signal at the time when the vehicle signal or the walking signal is output may be determined (S425).

Then, after receiving information about the vehicle signal or the walking signal currently output by the first signal output unit 100-2 installed in the opposite lane, the control unit 300 determines whether the vehicle signal or the walking signal is received, the received vehicle The signal or the walking signal information is compared with the result of the discrimination through the video information including the image from which the vehicle signal extracted from the first video is output (S430), and the first signal output unit 100-2 installed in the opposite lane ) Determines whether the vehicle signal or the pedestrian signal is normally output (S435), and the first signal output unit 100-2 installed in the opposite lane is the vehicle signal or the pedestrian signal normally output (S435- Yes), it is possible to detect a vehicle that violates a signal passing through a stop line at a time when a stop signal of the vehicle is output based on the determined vehicle signal or a walking signal.

However, here, the first signal output unit 100 may output a vehicle signal or a pedestrian signal for a pedestrian crossing, but the vehicle signal and the pedestrian signal may include a red signal for stopping and a blue signal for permitting passage. For convenience of explanation, in the following description, the first signal output unit 100 detects a vehicle that violates a signal or detects a vehicle that violates a speed according to the output vehicle signal, only when the first signal output unit 100 outputs a vehicle signal. I will explain the process.

Specifically, when the first signal output unit 100-2 installed in the opposite lane is in a state in which the vehicle signal is normally output (S435-Yes), the determined vehicle signal is a stop signal (red signal). ) (S440-Yes), based on the second video, when a stop signal is output, determines whether a signal violation vehicle passing through a crosswalk stop line is detected, and when a signal violation vehicle is detected, a plurality of the second video By extracting the image information including the image of the license plate area of the signal violation vehicle in the frame (S450), it is possible to recognize the vehicle number of the signal violation vehicle (S455).

Through the first video and the second video to be output at the same time, when the information on the vehicle number of the signal violation vehicle is received together, the received vehicle number of the signal violation vehicle is also the first video output screen and the second video The first video and the second video may be output through a screen different from the output screen (S460).

On the other hand, when the first signal output unit 100-2 installed in the opposite lane is in a state of normally outputting a vehicle signal (S435-Yes), the controller 300 determines that the determined vehicle signal is a stop signal (red signal). If it is not a passing permission signal (blue signal) (S440-No), the speed of a vehicle approaching the stop line of the crosswalk or the vehicle passing through the crosswalk stop line is measured based on the second video (S470).

In addition, the controller 300 may determine whether the speed of each vehicle is violated by comparing the speed limit information of a road section with a previously stored crosswalk based on the measured vehicle speed (S475).

At this time, when the speed violation vehicle is detected (S475-Yes), the controller 300 extracts image information including an image of the license plate area of the speed violation vehicle from among a plurality of frames constituting the second video (S480), speed The vehicle number of the violating vehicle may be recognized (S485).

In addition, the control unit 300 transmits information on the recognized vehicle number of the vehicle that violates the speed to the video output unit 400 together with the first video and the second video, so that the video output unit 400 basically displays each screen. When the first video and the second video are simultaneously outputted, when information on the vehicle number of the speeding vehicle and the measured speed of the vehicle are received together, the received vehicle number and speed of the speeding vehicle May be output together with the first video and the second video (S490).

Incidentally, not only is the information on the vehicle violating the signal or the vehicle violating the speed not only output through the output unit, but also stored on a separate server or transmitted to a separate external server, such as a police management server, to collect the penalty for the offending vehicle. Can be used to

Through this, it is possible to effectively detect a signal violation vehicle and a speed violation vehicle, and effectively transmit whether a signal violation vehicle and a speed violation vehicle are generated and detailed information to a manager who monitors traffic conditions occurring around the crosswalk.

8 is a view illustrating the operating characteristics of a smart traffic light system according to a second embodiment of the present invention.

In the smart traffic light system according to the present embodiment, when the second signal output unit 500 outputs a pedestrian signal for a pedestrian crossing installed on a road or intersection of two or more lanes (S805), the second photographing unit 600 crosses the pedestrian crossing. The third video for the second signal output unit 500-2 installed on the opposite side and the fourth video for the crosswalk are respectively photographed (S810), and the controller 300 controls the second signal output unit 500. Information about the gait signal output from the may be received (S815).

When the third video and the fourth video are respectively photographed, the controller 300 extracts video information including an image in which a pedestrian signal for a pedestrian crossing is output from among a plurality of frames constituting the third video at predetermined time intervals ( S820), it is possible to determine the walking signal at the time the walking signal is output (S825).

In addition, when the walking signal is determined after the second signal output unit 500-2 installed on the opposite side of the crosswalk receives information about the walking signal currently being output, the control unit 300 determines the received walking signal information. And the result of the discrimination through the video information including the image from which the gait signal extracted from the third video is output (S830), the second signal output unit 500-2 installed on the opposite side of the crosswalk walks normally If it is determined whether it is in the state of outputting (S835), when the second signal output unit 500-2 installed on the opposite side of the crosswalk is in a state of normally outputting a walking signal (S835-Yes), a plurality of fourth video forms By extracting the image information that contains the object from the frames of the object, the background and the object are separated, and the object with the separated background is classified as pedestrian, vehicle, and other objects based on the mobility, shape, and location of the object with the background separated. , Pedestrian teeth Pedestrian object information including information on the same sex, shape and location and vehicle object information including information on the mobility, shape and location of the vehicle are generated, and a signal of a pedestrian or vehicle on a pedestrian crossing based on the determined walking signal. It is possible to determine whether a violation has occurred or whether there is an accident between a pedestrian and a vehicle on a pedestrian crossing.

Specifically, when the second signal output unit 500-2 installed on the opposite side of the pedestrian crossing is in a state in which the walking signal is normally output (S835-Yes), the determined walking signal is a stop signal ( If it is a red signal (S840-Yes), it is possible to determine whether a contact accident has occurred between the pedestrian and the vehicle based on the generated pedestrian object information and information on the mobility and location of the pedestrian and the vehicle included in the vehicle object information (S845). ).

When a contact accident between the pedestrian and the vehicle is detected, the control unit 300 extracts image information on the contact accident situation between the pedestrian and the vehicle including the contact accident vehicle based on the fourth video, and the extracted contact accident situation. The image information may be output through the output unit (S855).

In addition, the controller 300 may recognize the vehicle number of the contact accident vehicle from the extracted image information on the contact accident situation, so that the recognized vehicle number is also output through the image output unit 400.

At this time, the video output unit 400, basically, the third video and the fourth video to be simultaneously output through each screen, but the contact information, the video information about the accident situation and the vehicle number of the contact accident vehicle is provided. When received together with the 3rd video and the 4th video, it is possible to display the video of the received contact accident situation and the vehicle number of the contact accident vehicle together with the 3rd video and the 4th video through separate screens.

On the other hand, when the second signal output unit 500-2 installed on the opposite side of the crosswalk is in a state of normally outputting a walking signal (S835-Yes), the determined walking signal is a stop signal (red). If the signal is not allowed to pass (blue signal) (S440-No), it is determined whether a signal violation vehicle passing through the stop line of the pedestrian crossing occurs based on the fourth video (S860), and if a signal violation vehicle is detected ( S860-Yes), among the plurality of frames constituting the fourth video, the image information including the image of the license plate vehicle license plate area may be extracted (S865), and the vehicle number of the signal violation vehicle may be recognized (S870).
