Next, the DS camera 4 configured as described above
A description will be given of a speeding vehicle cracking control system using the system. As shown in FIG. 1, the police car 1 tracks a speeding car, and first, the DS camera 4 connected to the GPS device 5 photographs the speeding car 2 (the photographing point at this time is point A). Then, the captured image and the GPS information obtained by the GPS device 5 are recorded on the PC card 150. still,
At this time, it is desirable to take a picture including the number of the speeding car in order to leave it as a proof photograph.

Then, the speeding vehicle 2 is tracked at the same speed for a certain period of time, and the speeding vehicle 2 is again photographed by the DS camera 4 (the photographing point at this time is point B). The GPS information obtained by the GPS device 5 is stored in a PC
Record on card. At this time, the speeding vehicle 2 is shot at the shooting distance at the time of shooting at the first point A, and the speeding vehicle 2 shot at the first point A and the second point B is taken.
Images are as large as possible. Alternatively, the speeding vehicle 2 is observed in real time by the DS camera 4, and the time when the image of the speeding vehicle 2 becomes the same size is automatically determined. At that time, the second shooting is automatically performed. I do. That is, by making the distances between the police car 1 and the speeding car 2 equal at the time of shooting at the point A and the point B, the average traveling speeds of the police car 1 and the speeding car 2 between the two points become equal. To do.

Next, these two captured images and GSP information recorded on the PC card 150 are read out to the master unit 3. To read data from the PC card 150 to the master unit 3, the PC card 150
After being taken out of the S camera 4 and loaded into a PC card drive (not shown) of the master unit 3, the PC card 150
Or the DS camera 4 and the master unit 3 may be connected by a cable and read via the output unit 130 of the DS camera 4.

The master unit 3 first calculates the traveling distance between the two points A and B where the two images were taken based on the positional information of the GPS information read from the PC card 150. This traveling distance may be simply a straight line distance between two points, or may be accurately determined from map data recorded in advance in the master unit 3 in consideration of the shape of the road. Alternatively, the measurement may be performed by a mileage meter provided on the police car 1 in conjunction with shooting.

From the time information of the GSP information, the travel time required to reach from the point A where the two images were taken to the point B is calculated, and the travel distance is divided by the travel time.
The average traveling speed between the two points is calculated. This average traveling speed indicates the average traveling speed of the police car 1 equipped with the DS camera 4, but as described above, the speeding vehicle 2 is photographed at the same distance at the points A and B as described above. The average traveling speed of the speeding vehicle 2 can be used.
Conversely, by photographing two images so that the image of the speeding vehicle 2 has the same size, the proof that the calculated average traveling speed is the average traveling speed of the speeding vehicle 2 Becomes In order to at least prove that the average speed of the speeding vehicle 2 is faster than that of the police car 1, it is necessary to take an image of the speeding vehicle 2 at least a second time from the beginning so that the image of the speeding vehicle 2 is smaller. Good.

When the traveling distance, traveling time, and average traveling speed are calculated as described above, the master unit 3
Based on the position information of the S information, a map including points A and B, which are shooting locations, is read from the pre-recorded map data, and an evidence report 8 as shown in FIG. Output). The evidence report 8 shown in FIG. 3 includes the speeding car 2 taken at the points A and B.
Images 8A and 8B are displayed, and the captured images 8A and 8B
Character information indicating the shooting location and shooting time (GPS)
Information) is displayed. According to the captured images 8A and 8B, A
It is proved that the distance between the speeding car 2 and the police car 1 at the point and the point B is equal.

In the evidence report 8, a road map 8C including the points A and B is displayed. On the road map 8C, the legal speeds between the points A and B and the two points A and B (see FIG. 80 km / h) and the average running speed (running speed) between the two points A and B calculated from the GPS information (150 km / h in the figure). Accordingly, when the displayed average traveling speed exceeds the legal speed, the evidence report 8 proves that the vehicle is a speed violation, and the speeding vehicle 2 can be controlled.

In the above-described embodiment, the captured image and the GPS information are obtained by the DS camera 4 to which the GPS device 5 can be connected and are recorded on the PC card 150. However, the present invention is not limited to this. The DS camera 4 captures only the captured image and immediately transfers the captured image to the master unit 3. The master unit 3 directly transmits the GPS information from the GPS device 5 in synchronization with the capturing performed by the DS camera 4. You may make it take in.

[0029]

As described above, according to the present invention, the captured images at two locations where the image of the speeding vehicle was captured at the same size, and the GP obtained from the GPS device at the two locations.
By printing the S information and the average traveling speed between the two points calculated from the GPS information at the two points as an evidence photograph, it is possible to objectively prove the speed violation of the target vehicle, and show the evidence photograph. You can crack down on speeding cars.
