In the present embodiment, in order to search for a vehicle, a database of vehicle hues, warehousing times, and vehicle widths is created, and a quick and accurate search is performed.

The parking facility has a large number of storage rooms, and each storage room is composed of a number of stratified parking rooms. Then, the vehicle that has entered the arbitrary storage room is moved up and down by a lift device (not shown) and parked in the corresponding parking room. When the vehicle enters the parking facility (Step 8, Step S110) and stops before the gate that issues the parking ticket in the parking room (Step 9), the parking facility control PLC 2 assigns the parking ticket number and the parking room number. (Step 10, Step S120), and a corresponding parking ticket is issued (Step 11, Step S130).

The parking ticket number is a series of numbers added to each vehicle, and the parking room number is the number of a rack where the vehicle is parked. The stage and row of the rack where the vehicle is parked are determined by the parking room number. At this time, the vehicle entry confirmation unit 1 mounted on the input side of the entry room detects whether or not the entry of the vehicle is possible, and outputs a signal corresponding thereto to the parking facility control PLC 2.

The parking facility control PLC 2 calculates the parking time of the vehicle in accordance with the signal output from the vehicle parking confirmation section 1 (step S150), and drives a ticket issuing device (not shown) to store the parking ticket number of the vehicle and the parking time. A parking ticket that records parking information corresponding to the room number and the parking time of the vehicle is issued.
When the parking ticket is issued, after confirming that there is no person in the storage room, the gate of the storage room is opened (step 13). When the gate is opened and the vehicle enters the storage room, the camera, which is the video input unit 4 mounted on the storage room, captures the vehicle (step S150) and outputs the corresponding video data to the multiplexed video connector 5. (Steps 14 and 1
5, 10).

After issuing the parking ticket, the parking facility control PLC 2 outputs a channel selection signal corresponding to the entry room where the vehicle is currently stored to the multiplexed image connector 5, and the parking information of the currently entered vehicle, that is, the parking information, that is, Storage time, storage date,

The video data is stop video data, and the video data and the parking information are stored in the hard disk 17 for each vehicle. At this time, the hard disk 1
The information stored in 7 is the date when the vehicle was entered, the entry time, the parking room number, and the video data of the entered vehicle according to the parking ticket number.

As described above, if the user of the parking facility loses the parking ticket while the vehicle is parked in the corresponding parking room, the stored parking information is not known. In this state, when the user provides the approximate parking time of the vehicle to the parking facility manager (step 28), the parking facility manager searches the stored parking information and video data using the parking time of the vehicle. Thus, the user's vehicle can be confirmed according to the search result output to the monitor 3 (steps 25, 24, 23, 27, 29).

Therefore, the parking ticket is reissued, and the vehicle can be taken out of the vehicle smoothly (step 30). The vehicle leaving operation according to the confirmation of the parking information when the parking ticket is lost will be described in detail with reference to FIG. When a parking facility user loses a parking ticket and declares so, a lost signal is input. On the basis of this, the manager inputs the approximate warehousing time when the user's vehicle has been stored using the keyboard (step S2).

Reference numeral 16 denotes an image comparison between the storage room image data (A image) when the vehicle is stored and the storage room image data (B image) when the vehicle is not stored in the width region of the vehicle engine cover. The difference area of the vehicle width between the two images is detected, and the entry room image data when the vehicle is not entered is deleted (steps S330, 340, and 350).

In the above description, the difference area of the vehicle width is detected by setting a rectangular area 41 of the engine lid part and the engine lid side part of the vehicle in the two video data, and the difference area of the vehicle width is a sensitivity according to the photographing time of the camera. Due to a change, a change in the illuminance of the vehicle storage room, or the like, noise may be generated when only a region where the vehicle is present is separately detected in comparison between when the vehicle is stored and when the vehicle is not stored.

Accordingly, C of the parking management video computer 6
When the vehicle width difference region is detected in accordance with the region comparison, the PU 16 removes noise of the vehicle width difference region detected by the filtering operation, and then calculates the area of the noise-removed vehicle width difference region. The size of the vehicle width is determined according to (step S360). The size of the detected vehicle width can be divided into each stage. In this embodiment, the detected vehicle width is set to be divided into a large vehicle, a medium vehicle, and a small vehicle (step S370).

After detecting the vehicle hue and vehicle width, the CPU 16 stores the vehicle hue, vehicle width, and video data corresponding to the vehicle along with parking information such as the parking ticket number, parking date, and parking time. Is stored for each vehicle in the corresponding area. In the state where the vehicle is parked in the corresponding parking room as described above, if the parking facility user loses the parking ticket and a lost signal is input, the manager determines the hue and the parking time of the vehicle and the vehicle as in the above-described embodiment. Enter information for the width.

For example, if the vehicle of the user who lost the parking ticket is red and the vehicle width is a medium-sized car, and the entrance time is about 2:00 pm, the parking management image computer C
The PU 16 is stored from the hard disk 17 at about 1 hour at a storage time of 2:00 pm, searches for data of a vehicle corresponding to a medium-sized car in red, and displays the searched vehicle data on the monitor 3 in order.

Therefore, unlike the above-described embodiment, the vehicle can be searched more quickly by further adding a search condition corresponding to the vehicle width and searching for the vehicle.
