2 illustrates an intersection traffic surveillance system or an intersection traffic surveillance method according to an embodiment of the present invention.

The intersection traffic surveillance system or the intersection traffic surveillance method of the present invention can capture all the vehicles moving at the intersection without using a blind spot by using the flight shooting unit 300. [

As described above, an intersection is a vehicle in which many vehicles are operated, so that when one vehicle interrupts a tail, it becomes a butterfly effect, which can cause a lot of traffic congestion.

The present invention repeats a method of photographing a traffic light using the flight shooting unit 300 and photographing a vehicle that violates the signal without stopping when the traffic light is a stop signal to monitor whether or not the vehicle at the intersection has been violated.

FIG. 3 shows the flight shooting unit 300 of the present invention.

The flight photographing unit 300 of the present invention is formed to include a body part 310, a flight wing part 320, a leg part 330 and a camera 350.

The body 310 may include a controller 400 and various PCBs.

The body 310 has a plurality of flight wings 320 formed along the periphery of the body 310 at an upper portion thereof. The flight wing 320 can be manufactured in the form of a propeller like a helicopter. The flying blade unit 320 allows the flying image pickup unit 300 to be moved in the air or hoverable.

The leg portion 330 is formed to extend from the lower side of the body portion 310 at a corresponding position. The leg portion 330 supports the body portion 310. The leg portion 330 is formed with a predetermined length so that the camera 350 can be positioned between the leg portions 330. A rechargeable battery 340 is installed under the leg portion 330.

The charging battery 340 of the leg portion 330 abuts the charging pad 232 of the standby box portion 200 and is charged.

The charging battery 340 supplies electric energy to various devices of the flight shooting unit 300 to operate.

The flight shooting unit 300 is provided with a GPS. Therefore, the position of the flight shooting unit 300 is transmitted to the control unit 100 in real time.

A laser sensor 420 may be installed in the body 310.

The laser sensor 420 is composed of a firing unit and a receiving unit.

The launching portion of the laser sensor 420 can emit a laser by a set range in the horizontal direction and the vertical direction. Precisely, the laser sensor 420 emits a laser to the horizontal portion of the traffic light installed at the intersection.

The laser sensor 420 receives the laser beam reflected from the signal lamp and transmits the sensed value to the controller 400. The controller 400 receives the sensing value transmitted from the receiver of the laser sensor 420, and measures the altitude of the flight photographing unit 300 based on the distance to the signal light and the traffic light using the preset data.

The control unit 100 can receive and confirm the position of the flight shooting unit 300 in real time using the GPS and receives the position of the current flying shooting unit 300 using the altitude sensor 430. However, The position and the altitude of the flying image pickup unit 300 measured through the image pickup unit 430 may be different from the position where the actual flying image pickup unit 300 is disposed.

For example, the difference between the position measured by the GPS and the actual flying image pickup unit 300 is about 5 m to 10 m.

It is important that the flight shooting unit 300 photographs the traffic light and the vehicle, but it should be avoided when the driver of the vehicle confirms the signal of the traffic light. Therefore, the laser sensor 420 is used to measure the position between the flying image pickup unit 300 and the signal lamp and the altitude of the flying image pickup unit 300, and the position and altitude of the flying image pickup unit 300 .

For example, when the flight taking unit 300 is located too close to the traffic light, the flight taking unit 300 is moved backward. When the flight taking unit 300 is located at the same altitude as the traffic light, Therefore, the altitude of the flight photographing unit 300 is moved high.

The camera 350 may be installed in the body 310 and disposed between the legs.

The camera 350 can photograph one direction. The camera 350 can be tilted. That is, when the camera 350 is tilted at the first angle, it can photograph the traffic light, and when it is tilted at the second angle, it can photograph the vehicle.

A plurality of cameras 350 may be installed on the body 310.

For example, the camera 350 includes a first camera 350 capable of photographing any one direction and a second camera 350 photographing a direction opposite to the direction in which the first camera 350 photographs.

Here, the first camera 350 and the second camera 350 may be tilted at a first angle and a second angle, respectively. Therefore, since the directions in which the first camera 350 and the second camera 350 are symmetrical with respect to each other are photographed, all directions of the intersection can be photographed when the flight photographing unit 300 rotates only 90 degrees.

And the second position sensing sensor 355 may be installed at the center of the bottom of the flight shooting unit 300. [ And may be installed at a lower portion of the camera 350 as an example.

The second position detecting sensor 355 reacts with the first position detecting sensor 233, and the exact contents will be described later.

4 shows an intersection traffic monitoring system of the present invention.

The control unit 100 transmits commands and receives information wirelessly. The control unit 100 wirelessly transmits a command to the control unit 400 of the flight shooting unit 300 and receives various kinds of information received by the control unit 400. [

The control unit 400 transmits the state of the rechargeable battery 340 of the flying image pickup unit 300, the image measured by the camera 350 and the sensing value measured by each sensor to the control unit 100.

The attitude sensor 410, the laser sensor 420, and the altitude sensor 430 are installed in the flight shooting unit 300, and the control unit 400 is connected to each sensor.

The posture sensor 410 measures the level of the flight photographing unit 300. That is, if the flying image pickup unit 300 is hovered or operated in an inclined state without flying horizontally, such a position sensing value is output to the control unit 400.

The control unit 400 outputs the posture correction signal to the control unit 400. The control unit 400 outputs the posture correction signal to the flying image pickup unit 300 and outputs the posture correction signal to the horizontal Correct the figure.

As described above, the laser sensor 420 fires and receives a laser beam, and measures the distance and altitude of the flight photographing unit 300 with the traffic light.

Here, it will be appreciated that the laser can be fired, received, and recognized in the vicinity of the flight shooting unit 300. [

The altitude sensor 430 measures the altitude of the flight photographing unit 300. [

As described above, according to the altitude of the traffic lights and the flight shooting unit 300, the driver can obscure the view of the traffic lights. The altitude of the flight taking unit 300 measured by the laser sensor 420 is measured on the basis of the traffic light and then the altitude of the flight taking unit 300 is corrected through the control unit 100 and the control unit 400 .

For example, the control unit 400 receives the altitude sensing value output by the altitude sensor 430, receives the altitude of the flight photographing unit 300 based on the measured traffic light through the laser sensor 420, To the control unit (100). The control unit 400 outputs an altitude correction signal to the flying image pickup unit 300 and outputs the altitude correction signal to the control unit 400. The control unit 400 outputs the altitude correction signal to the control unit 400, The altitude of the flight shooting unit 300 may be modified in a form of modifying the altitude.

The sound detection sensor 440 is set to the set dB. The sound detection sensor 440 outputs a sound sensing value to the control unit 400 when a sound of a predetermined dB or more is sensed.

The purpose of installing the sound detection sensor 440 is to measure the occurrence of a traffic accident.

The control unit 400 transmits the sound sensing value to the control unit 100 when the sound sensing value is output. The control unit 100 receiving the sound sensing value causes the controller 350 to tilt the camera 350 at a third angle. The third tilting angle is the angle of the camera 350 measuring the intersection.

Here, an image photographed through the camera 350 is transmitted to the control unit 100, and the control unit 100 confirms the presence or absence of a traffic accident through the camera 350. FIG.

When a traffic accident occurs, the control unit 100 transmits the image of the camera 350 and the corresponding position to the emergency center control room. Accordingly, the control unit 100 can quickly respond to traffic congestion situations caused by human injury or traffic accidents.

The camera 350 may be tilted at an angle set by the control unit 400. [

And is tilted at a first angle, a second angle, and a third angle as described above. When the camera 350 is tilted at the first angle, the camera 350 photographs the traffic light, and when the camera 350 is tilted at the second angle, the camera 350 photographs the vehicle, and when the camera 350 is tilted at the third angle, .

As described above, the control unit 400 receives the image captured by the camera 350 and transmits the received image to the control unit 100. Accordingly, the control unit 100 can transmit an appropriate command to the control unit 400 according to the received image of the control unit 400.

Fig. 5 shows the atmospheric box part 200 of the present invention.

The waiting box part 200 is installed at a position having a set height based on the ground.

In order to prevent the waiting box unit 200 from being touched by the hands of the user or to prevent the flight shooting unit 300 from being lost, the standby box unit 200 is installed with the height set as described above.

The waiting box unit 200 receives a command from the control unit 100 and opens and closes the door that communicates or interrupts the outside with the inside. A space is formed in the atmosphere box part 200.

The standby box unit 200 includes a base 230 disposed at a lower portion thereof and a door disposed at a side of the base 230 and connected to the base 230 through a hinge connection.

The door may include a first door 210 and a second door 220.

The standby box unit 200 includes a motor 500, a gear 510 installed on a shaft of the motor 500 and rotating in accordance with the rotation of the shaft, and a hinge unit 500 disposed on a side surface of the base unit 230, And a hinge coupling gear 520 formed along the coupling.

The motor 500 may receive a command to open the door by the control unit 100. [ Upon receiving the command to open the door, the motor 500 makes a set rotation, and the door is opened in accordance with this rotation.

The motor 500, the gear 510 and the hinge coupling gear 520 may be installed in the first door 210 and the second door 220, respectively. Accordingly, each of the motors 500 receiving the command to open the door of the control unit 100 opens the first door 210 and the second door 220 to communicate with each other.

5, the first door 210 may be located at the upper portion of the second door 220 and may be observed in a superimposed manner.

The first door 210 may be provided with a sealing part 225. The sealing part 225 may be made of a synthetic resin to prevent the first door 210 and the second door 220 from being opened by an artificial force.

A charging pad 232, a traffic light display unit 231, and a first position sensing sensor 233 are installed in the base unit 230.

The filling pad 232 is formed at a position where the leg portion 330 of the flying image pickup unit 300 abuts. The charging pad 232 is disposed at the leg portion 330 of the flying image pickup unit 300 having the set weight. That is, the charging battery of the leg portion 330 is disposed on the charging pad 232.

When the flight shooting unit 300 is in flight, the charge battery 340 is exhausted. Therefore, only the leg portion 330 of the flying image pickup unit 300 is disposed on the charging pad 232 of the base portion 230 of the standby box portion 200, (340).

Here, the filling pad 232 includes a DB in which the model name of the flying image pickup unit 300 is stored. Therefore, the charging pad 232 can charge the rechargeable battery 340 only in response to the flying image pickup unit 300 of the model name of the stored DB. This is to prevent the rechargeable battery 340 from being charged when a flight shooting unit 300 other than the authorized flying shooting unit 300 is disposed.

A first position detecting sensor 233 is installed at the center of the waiting box part 200. The first position sensing sensor 233 exchanges information with the second position sensing sensor 355. That is, the first position detecting sensor 233 is disposed at the correct position with respect to the information on and from the second position detecting sensor 355 so that the charge battery 340 installed in the leg portion 330 To be precisely positioned on the charging pad 232.

This is because when the control unit 400 operates the flight capture unit 300 but the control unit 400 can not control the charge battery 340 of the flight capture unit 300 to be placed on the charge pad 232, So that it is possible to prevent inconvenience of manual charging during re-operation.

A signal lamp display unit 310 is installed at one side of the base unit 230. The traffic light display unit 310 displays the current status of each traffic light installed at the intersection. The traffic light display unit 310 is connected to the control unit 100 and outputs the status of the current traffic light to the control unit 100 in real time. Accordingly, the control unit 100 can accurately determine the state of the current traffic light, and can accurately predict the traffic light and the direction of the vehicle to be photographed by the flight photographing unit 300, thereby driving the flight photographing unit 300.

A temperature sensor, a humidity sensor and a wind measurement sensor are installed on one side of the waiting box. The temperature sensor measures the current temperature and transmits it to the control unit 100. The humidity sensor measures the current humidity and transmits the measured humidity to the control unit 100. The wind measurement sensor measures the current wind, Lt; / RTI > Accordingly, the flight shooting unit 300 is prevented from operating during bad weather or windy weather, thereby increasing durability.

8 is a block diagram of an intersection traffic monitoring method of the present invention.

The intersection traffic surveillance method of the present invention includes a waiting step S1, a start command output step S2, a start flight step S3, a position adjustment step S4, a first photographing step S5, a second photographing step S6 , And a photographing ending step S7.

The intersection traffic surveillance method of the present invention performs the same functions as the above-described intersection traffic surveillance system according to each step.

The waiting step S1 is a step S1 of setting the charging battery 340 installed in the leg portion 330 of the flying image pickup unit 300 in a state where the charging battery 340 is in contact with the charging pad 232, And is placed in a waiting state.

The start command output step S2 is a step of the control unit 400 transmitting the start shooting command to the control unit 400. [

The control unit 100 determines whether or not the operation of the flight taking unit 300 is performed by combining the respective sensed values transmitted from the temperature sensor, the humidity sensor and the wind measurement sensor described above, The position of the flight photographing unit 300 is determined according to the state of a traffic light of Thereafter, the control unit 100 transmits a start photographing instruction to the control unit 400 of the flying photographing unit 300 by radio.

In the start flight step S3, the door of the waiting box unit 200 is opened, and the flight photographing unit 300 moves to a predetermined position and hovering.

The first door 210 and the second door 220 are operated to open the waiting box unit 200 by the operation of the motor 500 and the flying photographing unit 300 is moved to a predetermined position Move to maintain current position and altitude.

The position adjustment step S4 is a step of adjusting the position of the flying image pickup unit 300, including a laser firing step a1, a position measurement calculation step, and a standby position adjustment step a3.

As described above, the flight photographing unit 300 is provided with the GPS and the altitude sensor 430, but the relative accurate distance and altitude with respect to the traffic light is important. Each step is required for this.

The laser firing step al is a step in which the laser sensor 420 formed in the flying image pickup unit 300 fires the laser horizontally and vertically with a signal lamp.

The calculation step a2 is a step of calculating an accurate distance between the flight photographing unit 300 and the signal light and a relative position with respect to the signal light through the amount of reflection of the emitted laser and the time of reflection.

The laser emitted as above is reflected from the traffic light and returned to the laser sensor 420. The reflected laser beam is transmitted to the control unit 100 through the control unit 400. The control unit 100 calculates the distance between the current signal lamp and the distance to the flight shooting unit 300 and the relative altitude based on the amount of the laser and the time based on the value of the received laser sensor 420. [

The standby position adjusting step (a3) is a step of adjusting the position of the flying shooting unit 300 so as to adjust the position and the altitude of the flying shooting unit 300 according to the value calculated by the control unit 100. [

In the first photographing step S5, the camera 350 installed in the flight photographing unit 300 is kept at the first angle and the first signal lamp is photographed. When the first signal lamp is changed to the stop signal, The camera is rotated at an angle set in the second direction, which is the signal direction in which the vehicle travels, and the camera 350 is tilted at the second angle to photograph a vehicle that violates the signal.

Here, as described above, two cameras 350 may be installed in opposite directions. Therefore, the above-described shooting of the flight shooting unit 300 is one shot but covers two sections of the intersection.

When the predetermined time has elapsed in the first photographing step S5, the second photographing step S6 is performed.

The second photographing step S6 photographs the second traffic light by tilting the camera 350, which has been tilted in the second direction at the second angle, to the first angle. Thereafter, when the second signal lamp is changed to the stop signal, the flight photographing unit 300 is rotated at the set angle so as to photograph the first direction, and the camera 350 is tilted again at the second angle to photograph the vehicle.

The first shooting step (S5) and the second shooting step (S6) are repeated, and the vehicle that violates the signal is interrupted.

When the control unit 100 outputs a shooting end command to the control unit 400 and the standby box unit 200, the door of the standby box unit 200 is opened again. In the shooting ending step S7, The door is closed after the charging battery 340 installed in the leg portion 330 of the flying image pickup unit 300 is disposed in the internal space and is disposed in the charging pad 232 of the inner space of the standby box portion 200 to be.

Here, the photographing ending step S7 may include a waiting position adjusting step a3.

When the controller 100 detects that a traffic accident has occurred at the intersection by tilting at the third angle as described above, the control unit 100 transmits the location of the photographed image and the intersection to the emergency control center. The Emergency Control Center will then respond to the emergency situation based on the information received.

FIG. 6 shows an operation sequence of the intersection traffic monitoring system or the intersection traffic monitoring method of the present invention.

FIG. 7 illustrates how the camera 350 of the flight shooting unit 300 of the present invention operates according to the first shooting signal and the second shooting signal.

As can be seen from Fig. 6 (a), the flight photographing unit 300 is disposed in the waiting box unit 200 disposed on one side of the lane.

The control unit 100 examines whether or not the flight shooting unit 300 is operating through the respective sensed values transmitted by the temperature sensor, the humidity sensor, and the wind measurement sensor installed in the standby box unit 200.

After the control unit 100 determines the operational state of the traffic lights according to the traffic light display unit 310 as shown in FIG. 6 (b), the control unit 100 determines to operate the flight capture unit 300, When the start photographing command is transmitted wirelessly, the motor 500 of the waiting box unit 200 rotates in one direction to open the first door 210 and the second door 220. In addition, the control unit 400 outputs a flight signal to the flying image pickup unit 300 so that the flying image pickup unit 300 moves to a predetermined intersection position to maintain the hovering state.

Thereafter, the laser sensor 420 is operated to measure the relative distance and the relative altitude between the signal lamp and the flying image pickup unit 300, and transmits the laser sensing value to the control unit 100 through the control unit 400. The control unit 100 resets the position and altitude of the flying image pickup unit 300. [

Here, the image of the first signal or the like is transmitted to the control unit 100. When the first signal or the like detects the stop signal, it outputs a rotation signal and a second photographing signal to the flight photographing unit 300 and the camera 350 so that the flight photographing unit 300 can detect the stop signal before the first signal is changed to the stop signal The camera 350 is rotated in the second direction in which the vehicle has been signaled to move, and then the camera 350 is tilted at the second angle to photograph the signal-violating vehicle.

6 (c), if there is no vehicle that is violated as shown in FIG. 6 (d), the control unit 100 outputs a first photographing command, and when the first photographing command is received, (400) outputs the first photographing signal. The camera 350 receiving the first photographing signal tilts to the first angle and photographs the second signal.

6 (e), when the second signal is changed to the stop signal, the rotation signal and the second photographing signal are outputted to the flight photographing unit 300 and the camera 350, and the flight photographing unit 300 Moves in the first direction in which the vehicle has been signaled to move before the second signal lamp is changed to the stop signal, and then tilts the camera 350 to the second angle to photograph the signal-violating vehicle.

6 (b) to 6 (e) are repeated with such an operation. Here, if the charge battery 340 of the flying image pickup unit 300 is equal to or less than a preset amount, the control unit 400 outputs a warning signal to the control unit 100. When the control unit 100 outputs a shooting end command The door of the waiting box unit 200 is opened again and the charging battery 340 installed in the leg portion 330 of the flying image pickup unit 300 comes into contact with the charging pad 232, And the door is closed again.
