Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an illustration of an imaging photograph applied to the present invention.

The photographed photograph shows the position indicator lines 1, 2, 3, and 4 for identifying the camera installed on the road and the distances 10m, 30m, (50m), (70m) are displayed. Further, the speed reference line 5 and the speed reference lines 6, 7, and 8 are displayed on the photographed image. (0 km / h), (20 km / h), (50 km / h), and (80 km / h) are displayed on the speed reference line 5 and the speed indicator lines 6, 7, .

1 (1a) is a photograph taken at 2006-03-23 at 13: 24: 24.01 when the vehicle passes through, and FIG. 1 (1b) shows a photograph taken at 3 seconds after the imaging time of FIG. This is a photographed picture.

1 (1a) and 1 (1b) show the time of imaging. In the illustrated photograph, the instantaneous velocity at the time measured by the actual laser apparatus is displayed, but it may be omitted according to the embodiment.

1 (1b), which is a picture taken three seconds later, if the vehicle is present in the position indicating line 4 at 70m, the average speed of the vehicle is 0km / h. This corresponds to the case where the vehicle is located at the speed reference line 5 (0 km / h). If the vehicle is located at 50 m positional line 3 in FIG. 1 (1b), the average speed of the vehicle is 24 km / h and the speed of the speed line (20 km / h) The vehicle exists.

Likewise, if the vehicle is located at 30 m position indicator line 2 in FIG. 1 (1b), the average speed of the vehicle is 48 km / h, at which time the vehicle approaches the speed indicator line (50 km / h) Further, if the vehicle is located on the 10-m positional line 2, the average speed of the vehicle is 72 km / h, and the vehicle is beyond the speed limit line (70 km / h)

In this case, each of the speed indicator lines shown in (1b) of FIG. 1 is a line in which the average speed of the vehicle is calculated three seconds after the imaging time of (1a) in FIG. Knowing the speed, you can see the speed of the vehicle without the need for special equipment. Actually, in FIG. 1 (1a), the vehicle is picked up at a position of 75 m, and since the vehicle is picked up at the position of 3 m in FIG. 1 (1 b), the travel distance for 3 seconds is 72 m and the average speed at this time is 85 km / h. Therefore, the vehicle exists beyond the speed limit line (70 km / h) (8). 1 (1a) and 1 (1b) were experimented on a school zone with a speed limit of 50 km / h in the vicinity of the school. As shown in FIG. 1 (1a) It is possible to immediately recognize that the vehicle of the picture photographed in the photographing device exceeds a distance of 50 km / h, which can be recognized by two photographs without using a speedometer with a special laser device.

2 is a block diagram of a system for implementing a first embodiment of the present invention.

The control section 3 of the present embodiment is connected to a camera driving section 2 for driving the camera 1 and has a storage section 4 in which the position and shape of the leader line in the photograph and the distance and speed corresponding to the respective leader lines are stored A display unit 5 connected to the display unit 5 for displaying the photographed image of the camera 1 and the marker stored in the storage unit is connected and a printing unit 6 for printing an image displayed on the display unit is connected, 3, an input unit 7 for inputting specific commands and data, and an interface 8 connected to an external communication network for transmitting and receiving data.

FIG. 3 is a flowchart illustrating an operation procedure of an embodiment of the present invention.

The control unit 3 displays an image of the position indicator lines to be displayed on the captured image input from the input unit 7, position coordinates displayed on the image of the position indicator lines, The position coordinates at which the distance mark and the distance mark are to be displayed, the position coordinates displayed on the image of the speed guides and the image of the speed guides to be displayed on the sensed image, and the speed markers indicated by the speed guides and the position coordinates And stored in the storage unit 4 (S1).

The control unit 3 controls the camera driving unit 2 so that the camera 1 picks up an image of the road at step S2 and S3 the camera 1 And stores the synthesized image in the storage unit 4 and displays the synthesized image on the display unit 5 in step S4.

It is a matter of course that an imaging command can be inputted to the control unit 3 when the speed of the vehicle entering the speed measuring section exceeds a predetermined speed by various speed detecting devices including a laser.

The control unit 3 controls the camera driving unit 2 so that the camera captures a second time when three seconds elapses after the first imaging ends. When a second captured image is input to the control unit 3 by the camera 1, a composite image is formed by synthesizing the mark and the time data stored in the storage unit 4 in the second captured image, (S5), (S6), (S7), and (S8) on the display unit 5 while storing them in the storage unit 4.

The display unit 5 displays the first composite image and the second composite image together so that the user can easily compare the two images and determine whether or not to overspeed. If the speed is excessive, the control unit 3 issues a print command (S9), and transmits an image or necessary data to the outside via the interface 8 to the external communication network.

4 is a block diagram of a system of a second embodiment of the present invention.

The second embodiment is different from the first embodiment in that a laser apparatus is provided in the first embodiment and a first composite image is formed with respect to a vehicle which is overspeed by calculating the speed of an incoming vehicle by a laser, .

The system of the second embodiment is provided with a laser apparatus 20 for judging whether or not the vehicle is overspeed at 70m as shown in (1a) of Fig. The laser apparatus 20 includes a laser driving unit 10 for irradiating a laser from a laser irradiating unit 9 under the control of a control unit 3 and a reflecting unit 20 for reflecting the laser irradiated from the laser irradiating unit, And a laser light receiving unit 11 for receiving the laser beam.

The control unit 3 is connected to a speed calculating unit 12 that calculates the speed of the passing vehicle from the point of time when the laser is irradiated from the laser driving unit 10 and the point of time when the laser is received by the reflected laser receiving unit 11. The control unit 3 transmits an image pickup signal to the camera driving unit 2 when the speed of the passing vehicle at the 70m point calculated by the speed calculating unit 12 is greater than a predetermined speed, The camera 1 is operated to capture an image. The controller 3 transmits an image pickup signal to the camera driver 2 once again after a predetermined time of 3 seconds elapses and the camera driver 2 operates the camera 1 when the image pickup signal is inputted .

The process of forming the composite image is similar to that of the first embodiment, but the instantaneous velocity calculated by the velocity calculator 12 is synthesized by characters to form the composite image of FIG. 1A.

According to the present invention having the above-described objects and constitutions, it is possible to judge whether or not to overspeed by using only photographs without a special speed measuring device.

In addition, since it is possible to judge whether the vehicle is overspeed by not only the instantaneous speed but also the average speed by using the photograph, it is possible to control the drivers who are re-speeding after decelerating the speed close to the overspeed intermittent camera.

In addition, the reliability of the intermittent speed can be increased by providing the average speed for the intermittent operation with the two images together with the instantaneous speed measured by the laser apparatus.
