Abstract

PURPOSE:To monitor illegally parking vehicles with less labor by automatically detecting a vehicle parking at the same place in excess of predetermined time and issuing an alarm to the driver of the vehicle. CONSTITUTION:The picture information of a vehicle taken by means of an ITV camera l is kept in a video memory 4 after the information is digitized by means of a picture input device 2 and scanned and the number plate area of the vehicle is detected from the picture by performing a shape measuring process on the inputted picture information. After the number plate area is detected, the vehicle type code and numeric pattern of the license number of the vehicle are segmented. Then, after the characters are recognized by performing a feature analyzing process by referring to a dictionary contained in a central processing unit 3, the recognized characters are kept in the memory 4. When the elapse of a fixed period of time is confirmed by means of a timer function, the same processes are repeated and the obtained license number is compared with the kept license number. When the obtained license number matches the kept license number, the vehicle is judged as an illegally parking vehicle and the picture information of the vehicle is stored in a storage device 6 and, at the same time, an alarm is outputted.

Description

[Detailed description of the invention]

[Object of the invention]

0002

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illegal parking detection device for detecting illegal parking on roads where parking is prohibited.

0003

[Prior Art] Conventional illegal parking detection devices photograph road conditions using an industrial imaging device, constantly record the images on a video recorder, and allow humans to monitor or check the images later. illegal parking.

0004

[Problem to be Solved by the Invention] With the method in which humans judge images by looking at images, in order to find all illegal parking in no-parking zones at once, it is necessary to use a large number of industrial imaging devices installed at multiple locations on the road. It is necessary to monitor manually or to spend a lot of effort to view images from a video recorder installed in correspondence with industrial imaging equipment, which not only requires a large number of video tapes but also has the problem of poor work efficiency. be.

SUMMARY OF THE INVENTION An object of the present invention is to provide an illegal parking detection device that can automatically detect illegally parked vehicles at all times. [Structure of the invention]

[0006]

[Means and effects for solving the problems] The present invention provides an industrial imaging device that photographs the situation of a no-parking zone as image information, an image input device that digitizes the obtained image,
A video memory that temporarily stores this image information, a device that inputs part of the image information and reads the vehicle number, and a device that manages the time of the read vehicle number and determines that it is a parking violation if there is no change for a certain period of time. This is an illegal parking detection device equipped with a central processing unit that outputs the image information to a warning device and stores the image information in a storage device as evidence.It detects image information of the area including the monitored target and its surroundings using an industrial imaging device. Then, the obtained image information is digitized by an image input device and input to the central processing unit, which extracts the license plate of the vehicle from the input image information, reads the vehicle number, and parks the vehicle for a certain period of time. If a vehicle has been parked for more than a set time, it is output to the warning device as a parking violation, and image information is stored in the storage device as evidence.

[0007]

Embodiment An embodiment of the present invention is shown in FIGS. 1 and 2. Figure 1 shows an ITV camera 1 that is attached to a no-parking section of a road and captures the situation of parked vehicles as image information, an image input device 2 that digitizes the obtained image information, and an image input device 2 that stores all digitized image information. A video memory 4 that reads the image of the vehicle's license plate, and a character recognition board 5 that reads the image of the vehicle's license plate.
, a storage device 6 that stores images of illegally parked vehicles, a central processing device 6 that determines whether a vehicle has been parked for a predetermined period of time or longer, and detects a vehicle that has been parked for a predetermined period of time; This figure shows the configuration of the illegal parking monitoring device of the present invention, which includes an alarm device 7 that generates an alarm and outputs a stored image when the illegal parking occurs.

FIG. 2 is a functional flowchart of the present invention. In step S1, the image information of the ITV camera 1 is digitized by the image input device 2 and is scanned and stored in the video memory 4. In step S2, The input image information is subjected to shape measurement processing to detect the license plate area in the image, and in step S3, the numerical pattern of the vehicle model code and vehicle number in the license plate area is cut out,
Characters are recognized by checking against the internal dictionary of the central processing unit 3 and performing feature analysis processing, and in step S4, the original image is stored in the video memory 4, and in step S5, the timer function is used to delay the original image by a certain time Δt. Thereafter, similar step S1
~ S3 is repeated, and in step S6, the vehicle numbers obtained in the above two processes are compared, and if the numbers are the same, it is determined that there is a parking violation, and in step S7, the image information obtained in the two processes is stored in the storage device. 6 and outputs an alarm. If the numbers are different, the video memory 4 is reset in step 8, and the process returns to the first step S1 to repeat the same operation.

[0009]

[Effects of the Invention] As explained above, according to the present invention,
Vehicles parked on the road in no-parking zones are constantly monitored, vehicles parked for longer than the specified time are automatically detected, a warning is issued, image information is saved as evidence, and image information is generated as necessary. Since it is also possible to play back parking violations, it is possible to automatically monitor vehicles with parking violations with less effort.
