Next, the processing procedure of the automatic parking lot management apparatus according to the present invention will be described with reference to the flowcharts shown in FIGS.

FIGS. 12 and 13 illustrate the processing procedure when one imaging device 5A is used. In step S1, the processing area of the imaging device 5A is set to the first, second, and third areas. R1, R2, and R3 are set, the background image of each of the limited areas R1, R2, and R3 is stored in the next step S2. Then, in a third step S3, it is determined whether or not the previous processing and imaging were possible. If it is determined that it is possible, the process proceeds to step S4 to start imaging, and if it is not possible (in the case of failure), the process proceeds to step S5 to stop imaging,
In addition, the entrance path R is closed to prohibit entry of the vehicle MC.

In the next step S6, the taken image is processed and checked. Then, the flow advances to step S7 to determine whether or not an object exists in any of the areas R1, R2, R3 based on the image information. If YES, the process proceeds to step S8 to limit the area, and then the process proceeds to step S8.
12 to determine whether the gate bar 2 is open. If the gate bar 2 is closed, the process directly proceeds to A shown in FIG.
Is not seen and the vehicle MC receiving the parking ticket CK has already passed each condition, the gate bar 2
And the process proceeds to A in FIG.

On the other hand, if it is determined in step S7 that there is no object in any area, step S9
To determine whether the gate bar 2 is open,
If it is closed, the process directly proceeds to step S11, where the background image stored in step S2 is updated, and the process proceeds to step S11.
2 again, but if it is open, go to step S13.
The same determination and processing as described above are performed, and the process proceeds to step S11.

In the flowchart shown in FIG. 13, it is first determined in which area the imaged object is located. If the object is located in the first area R1 near the entrance, the processing from step S14 is performed. If it exists in the second area R2 in front of the ticket issuing machine 4, the processing from step S22 is performed, and if it exists in the third area R3 before and after the gate, the processing from step S32 is performed.

If it is determined in step S39 that the image is not detected by the imaging device 5A and that the monitoring area is not visible at all,
It is determined that there is an obstacle object in front of the imaging device 5A, and the process proceeds to step S41. If the image captured in step S40 is black, it is determined that there is a failure or an obstacle object, and the process proceeds to step S41. The alarm output and parking stop processing are executed, and the process returns to step S3.

The above steps S14, S22,
When the area is specified in S32, the next step S15,
The process proceeds to S23 and S33 to process the image, and then proceeds to steps S16, S24 and S34, respectively, where the object is in the vehicle MC.
Is determined, and if the answer is NO, an abnormal process is performed and the process returns to step S3. If the answer is YES, the process proceeds to steps S17, S25, and S35, and the vehicle M
The direction in which C is traveling is specified, and if the vehicle MC is traveling normally, steps S18, S26, S36 are respectively performed.
, But in steps S20, S30, and S38, the vehicle MC
Is determined to have come back, the process of occurrence of fraud is performed, and the process returns to step S3.

Further, when it is determined in step S18 that the vehicle MC has come from the general road side, step S1 is executed.
Proceeding to 9, the ticketing machine 4 issues a ticketing process and returns to step S3. If it is determined that the vehicle MC does not come from the general road side, the process proceeds to step S21 and the vehicle MC stops at the entrance for a long time. Is determined to be present, the process of occurrence of the abnormality is performed, and the process returns to step S3. In step S26, it is determined that the vehicle MC comes from the first area R1, and then, in step S27, a ticket is issued. It is determined that the parking ticket CK has been received from the machine 4, and furthermore, step S2
If it is determined in step 8 that the gate bar 2 is closed, the process proceeds to step S29 as a normal process, where the gate bar 2 is opened, the parking is enabled, and the process returns to step S3.

However, if both are determined to be NO in steps S26 and S27, and further to YES in step S28, the flow advances to step S31 to proceed to step S2.
The same long-term stop abnormality processing as in step 1 is performed and step S3 is performed.
Return to

In step S36, the vehicle MC
Is determined to have come from the second area R2, the process returns to step S3 as normal processing, but if it is determined that the second area R2 has not come, the process proceeds to step S37 and proceeds to step S21. Then, the same long-term abnormality processing as in S31 is performed, and the process returns to step S3.

FIGS. 14 and 15 show two image pickup devices 5A and 5A.
13 is a flowchart illustrating a processing procedure when B is used. The outline of the flowchart is substantially the same as the processing procedure when one imaging device 5A shown in FIGS. 12 and 13 is used. Specific processing by using the imaging devices 5A and 5B will be described.

In the flowchart shown in FIG.
Two cameras (imaging devices 5A and 5B) in step S52
If it is determined that the simultaneous processing by the two cannot be performed, the process proceeds to step S58, and it is determined whether or not both of the two imaging devices 5A and 5B are out of order, and any one of the imaging devices 5A or 5B is determined. Is available, the normal processing of steps S59 and S54 and thereafter is executed. If both of them are faulty, the process proceeds to the fault processing and closing processing of steps S60 and S61.

In the flowchart shown in FIG. 15, in step S91, the presence of an object is recognized in the fourth area R4 or R4 'of the imaging device 5A or 5B of the other party. Imaging device 5A or 5B
If the monitoring area is not visible, that is, if the image cannot be captured, it is determined to be a mischief, a warning is issued in the next step S92, and the image of the object is taken by the image capturing device 5A or 5B on the opposite side. After being sent to the computer 13, the process proceeds to step S95, where
A or 5B, and the remaining one imaging device 5A or 5B
Then, it is determined again in step S96 whether or not there is an object in each of the areas R1 to R4 '. If NO, the process returns to step S52 shown in FIG.
In this case, the process returns to C in FIG. 15 and the process is repeated.

Further, if the image taken by any of the imaging devices 5A or 5B is black in step S93, it is determined that one of the imaging devices 5A or 5B is out of order, and the process proceeds to steps S94 and S95. Going forward and the remaining one imaging device 5A
Or, the processing by 5B is continued.

The processing after step S65 executed when there is an object in the first area R1 and the processing in the second area R2
The processing after step S73 executed when there is an object in is the processing after step S14 shown in FIG.
The processing is the same as the processing after step S22, and the description thereof is omitted.

If it is determined in step S81 that there is an object in the third area R3, the flow advances to step S82 to check the object by image processing, and then to step S8.
It is determined in step 3 whether or not the object consists of only one vehicle MC. If YES, the same processing as steps S35 to S38 in FIG. 13 described above is performed in steps S84 to S87, but if NO Proceeds to step S88.

In step S88, it is determined whether or not there is another object other than the one vehicle based on the image information. For example, as shown in FIG. If a human is confirmed, the process proceeds to step S89 ', the object is imaged by the imaging device 5A or 5B on the other object side, the image information is sent to the host computer 13, and then the process proceeds to step S84 described above. However, if the determination in step S88 is NO, that is, if only humans or vehicles MT prohibited from entering the vehicle are shown in the image,
Proceeding to the next step S89, it is determined whether or not the gate bar 2 is open. If the gate bar 2 is open, the flow proceeds to step S90 to issue an entry prohibition warning, and an image of the person or the entry prohibition vehicle MT. After transmitting the information to the host computer 13, the process returns to step S52 shown in FIG. 14, but if the gate bar 2 is closed, the process returns to step S52.

The letters "camera" are recognized in the flowcharts shown in FIGS. 12 to 15, which are synonymous with the imaging devices 5A and 5B (for example, a CCD camera). In S90 and S92, after transmitting the image to the host computer 13, it is assumed that the staff looks at the monitor and takes various measures toward the site.
