Abstract

PURPOSE:To automatically decide illegal parking by recognizing the vehicle number of an illegally parked vehicle in an picked-up image obtained over the whole monitor area, and when the recognition time of the same parked vehicle reaches a set time, outputting a vehicle number signal relating to the illegal parking. CONSTITUTION:An image picked up by a camera 1 is obtained over the whole monitor area. A recognizing means 20 recognizes the vehicle number of an illegally parked vehicle from the image. When the recognition time of the same parked vehicle reaches the set time, an output means 22 decides the vehicle as an illegally parked vehicle and outputs the vehicle number signal of the same parked vehicle as a vehicle number signal relating to the illegal parking.

First, while giving a zoom control signal to the TV camera I and a depression angle control signal to the pan head 2 from the TV camera control means 24 of the illegal parking compatible terminal 15, the TV camera l takes an image of a parked vehicle in the monitoring area IO. Do (Step S
t). At this time, the television camera 1 changes its imaging direction in the direction of the depression angle over time by operating the pan head 2 based on the depression angle control signal, and thereby the starting point 10a of the monitoring area 10
Continuous imaging is performed from to the end point 10b and from the end point tab to the start point 10a.

Now, as shown in the side view of FIG. 4 and the plan view of FIG.
The direct separation distance between and the imaging point 3 is y1 The width of the monitoring area 71 is Wa1 The pixel length corresponding to the monitoring area width wa of the image sensor of the television camera I is wb The angle of depression of the television camera I is θ.
When the focal length of the television camera l is f, in the positional relationship in the side view of FIG. 4, tanθ=h/x and x
*+h! =y! The relational expression y3xf=wbXx is obtained in the positional relationship in the plan view of FIG. Therefore, from these three equations, the final L

That is, since Wa in the above final equation is constant over the width of the monitoring area 10, and wb is also constant over the pixel length of the image sensor, the depression angle θ and the focal pressure Mr are determined in a correlation. In this correlation, if the focal length r determined by calculation is applied to the changing angle of depression θ, an image having a desired constant length can always be obtained.

For example, the starting point 10a position of the monitoring area IO is 10 m from the TV camera l, and the ending point 10b position is 4 m.
0 m, the length of the monitoring area 10 is 30 m, the width wa is 1.5 m, and the height h of the TV camera 1 is 6 m.
m, when using a CCD image sensor with a length of 2/3 inch wb as an image sensor, the angle of depression θ changes in the range of about 310 to 8.5 degrees as the direction of the television camera changes, and the angle of depression θ changes in the range of about 310 to 8.5 degrees, and the By performing zoom control, the focal length r is changed from approximately 68 mm to a value of 237 ml11, so that an image of a constant length is always captured in a pixel having a length of 2/3 inch.

Return to step t and continue imaging. On the other hand, if a vehicle is parked at the imaging position and the vehicle number is to be detected in the image, timing is started (step S4), and the zoom control signal and depression angle control signal are stopped and the direction of the TV camera is The conversion and zooming operations are stopped, and the television camera is kept in a fixed state (step S5). Then, in this state, imaging is performed (step S6) to recognize the vehicle number (step S7), and when the same vehicle number as the vehicle number detected in step S3 is detected (step S8), time measurement starts in step 4. It is determined whether or not a set time has elapsed since then (step S9). If the set time has not elapsed, the process returns to step S6, and the operations from step S6 to step S9 are repeated until the set time has elapsed.
