Abstract

PROBLEM TO BE SOLVED: To precisely discriminate a which of which minimum ground clearance is nonstandard. SOLUTION: An image pickup device 21 picks up the image of at least the lower part of a vehicle passing through, and a minimum ground clearance nonstandard vehicle discriminating means 28 discriminates a minimum ground clearance nonstandard vehicle based on image information obtained by the device 21 and minimum ground clearance discrimination reference information set in advance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-minimum ground clearance vehicle detecting device for determining a vehicle having a non-minimum ground clearance.

[0002]

2. Description of the Related Art There is known a mechanical multi-story parking device for automatically carrying a vehicle that a driver gets off into a parking section on a predetermined parking floor. In this mechanical multi-story parking device, a parking area where a driver gets off, a traveling bogie arranged on a parking floor and running by itself,
A plurality of parking sections arranged side by side along the traveling path of the traveling cart, a lift that moves up and down so as to be able to stop on the parking floor, and transports wheels (tires) of the vehicle installed in each of these sections in the width direction of the vehicle. A traversing conveyor for transferring the vehicle, and moving the vehicle in the storage area from the storage area to the lift, from the lift to the traveling vehicle, from the traveling vehicle to the corresponding parking section,
Are transported in this order.

[0003] In such a mechanical multi-story parking device, there are protruding portions protruding from a wheel contact surface at various points of the device. As this protruding portion, for example, in a parking area, a front wheel is in contact with a front wheel to inform a vehicle entrance limit, or a front wheel positioning device that is installed on a front-wheel traversing conveyor and positions a front wheel. The front wheel stopper device locks and locks the front wheels to prevent displacement of the vehicle when the traveling vehicle accelerates and decelerates, the half door opening prevention device prevents the opening of the half door, and is installed corresponding to each traversing conveyor. Motor covers and chain covers are known. When the vehicle posture is corrected by a lift or a traveling vehicle, a sensor for detecting a wheel position on a traversing conveyor of the lift or the traveling vehicle is installed, and for the front wheels and the rear wheels based on the wheel detection by this sensor. Each of the traversing conveyors is driven to control the vehicle attitude. In this case, the sensor is a protruding portion that protrudes from the wheel contact surface.

Here, in a normal vehicle, a so-called minimum ground clearance, which is an interval between the lowest part of the vehicle excluding the wheels and the ground contact surface of the wheel, is secured at a predetermined level (the lowest part of the vehicle is a reference minimum ground clearance). There is no risk of interference with the protruding part, but for example, a vehicle with a low vehicle height due to remodeling, a vehicle with the cover at the bottom of the vehicle detached and hanging from the normal position, and a lip spoiler In a vehicle or the like that protrudes too much, a protrusion protruding downward from the bottom of the vehicle interferes with the above-mentioned protruding portion, and there is a possibility that the protrusions may be damaged or damaged.

[0005] Therefore, a photoelectric sensor is arranged at a vehicle entrance of the parking device or in the vicinity thereof, and a discriminating device discriminates a vehicle that does not meet the minimum ground clearance based on the detection result of the photoelectric sensor. 2. Description of the Related Art There is known a parking device that prohibits a foreign vehicle from entering a parking device, thereby preventing a protrusion of the parking device and a protrusion of the vehicle from being mutually damaged or damaged.

More specifically, a photoelectric sensor is installed at the side of the passing vehicle and substantially at the height of the reference minimum ground height in the above-described area to detect light blocking when the vehicle passes, and the number of times of light blocking is two.
If the number of times of shading is three or more, the discriminating device determines that the light is blocked by the wheels (front and rear wheels) and is not a vehicle that does not meet the minimum ground clearance. Light is blocked by protrusions other than wheels, and the vehicle is determined to be a vehicle that does not meet the minimum ground clearance.

[0007]

Here, a mudguard (mud cover) attached to the vehicle and projecting below the reference minimum ground clearance is located near the wheels, there is no contact with the projecting portion of the device, and The ground is thin and flexible, so it does not pose a problem because it escapes even when it comes into contact with the protruding part.However, the above photoelectric sensor detects the shading caused by these elements. There is a problem that it is mistaken as a foreign vehicle. Therefore, in order to avoid this erroneous recognition, the ratio between the light-shielding time by the wheel and the other light-shielding time is calculated by the discriminating device, and when this ratio is within a predetermined threshold value, it is judged that the mud is thin and the ground is judged. In some cases, this is not counted as the number of times of shading, but the speed of the passing vehicle is not constant. , The vehicle is determined to be a vehicle with a minimum ground clearance.

Further, in the above photoelectric sensor, there is a case where the vehicle is shielded from light by the water splash of the vehicle in rainy weather, and in this case also, the vehicle is determined to be a vehicle outside the minimum ground clearance standard. Further, in a vehicle whose vehicle height is lower than the reference minimum ground height as a whole, the number of times of shading may not be three or more, and it is difficult to determine.

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a non-standard vehicle with a minimum ground clearance that can accurately identify a vehicle with a minimum ground clearance. I do.

[0010]

According to the present invention, there is provided a non-minimum-height-standard vehicle detecting apparatus according to the present invention, wherein an image pick-up device for picking up an image of at least a lower part of a passing vehicle and image information obtained by the image pick-up device are set in advance. A non-minimum ground clearance vehicle discriminating means for determining a non-minimum ground clearance vehicle based on the minimum ground clearance discrimination reference information.

[0011] According to the above-configured vehicle detection device with a minimum ground clearance, the imaging device captures an image of at least the lower part of the passing vehicle, and the non-minimum ground clearance vehicle discriminating means obtains the image with the imaging device. The vehicle that does not meet the minimum ground clearance is determined based on the obtained image information and the preset minimum ground clearance determination reference information. Since the discrimination is performed using the image information as described above, when the speed of the passing vehicle fluctuates, for example, accurate image information corrected in speed based on the obtained image information is obtained. For example, based on the width or area of the image information, the positional relationship with the wheels, etc., for example, grounding, splashing of water of the vehicle in rainy weather, mudguard, etc. are excluded from the determination, and the vehicle height is generally a reference minimum ground clearance. A vehicle having a lower height, a substantial protrusion lower than the reference minimum ground clearance, is determined to be a vehicle with a minimum ground clearance.

The non-minimum ground clearance vehicle discriminating means is, for example, a minimum ground clearance acquiring means for obtaining a substantial minimum ground clearance of a vehicle based on image information obtained by an image pickup device. And a comparison determining means for comparing the minimum ground clearance obtained by the minimum ground clearance obtaining means with the reference minimum ground clearance as the minimum ground clearance determination reference information to determine a vehicle with a minimum ground clearance non-standard. Is adopted.

The comparing and determining means gives a predetermined display command to the display means when the passing vehicle is determined to be a vehicle which does not meet the minimum ground clearance. When the display means receives the predetermined display command, the display means receives the predetermined display command. It is preferable to indicate that entry is prohibited.

When such a configuration is adopted, a vehicle outside the minimum ground clearance is quickly exited in accordance with a display indicating that vehicle entry is prohibited by the display means.

[0015] The imaging device is installed in a vehicle entrance of the parking facility or in a parking area where the vehicle is parked by the driver's operation and the driver gets off the vehicle, and a display means is provided in the vehicle entrance or the parking area. If it is installed in a position where the driver can see it in front, further entry of parking facilities outside the minimum ground clearance into the parking lot facility is prevented, and the protrusion of the parking facility and the projection of the vehicle outside the minimum ground clearance standard are prevented. Interference with an object is prevented beforehand.

Further, as the image pickup device, specifically, for example, a line sensor camera is employed. The line sensor camera makes the device inexpensive. As another imaging device, for example, a television camera can be cited.

The above-mentioned minimum ground clearance non-standard vehicle detection device has a parking area where a vehicle is parked by a driver's driving and the driver gets off the vehicle, a plurality of parking spaces for accommodating the vehicle, and a parking space. A lift that can be lifted and lowered so as to be able to stop on the parking floor, a traveling bogie that is arranged on the parking floor and runs by the side of the parking section, and a vehicle mounted on each of these is transported in the width direction of the vehicle to transfer the vehicle And a traversing conveyor to be transferred, and each of the traversing conveyors,
When applied to a mechanical multi-story parking device that relays a lift and a traveling trolley and carries it into the corresponding parking stall of the parking stalls, the mechanical multi-story parking device has a large number of protrusions that protrude from the wheel grounding surface. Thus, the function of the vehicle detection device that is not the minimum ground clearance is fully exhibited.

It should be noted that any other display may be used as long as these can be displayed.

Further, as shown in FIG. 1, the minimum ground clearance non-standard vehicle detecting device 20 includes information for determining image information to be excluded when discriminating the reference minimum ground clearance and the minimum ground clearance non-standard vehicle (hereinafter, simply referred to as a vehicle). (Referred to as discrimination exclusion information) as a minimum ground clearance discrimination reference information, and a memory 31 for storing minimum ground clearance discrimination reference information, and a RAM 31 for temporarily storing predetermined information.

Further, the vehicle height detecting device 2 which is not the minimum ground clearance standard

A vehicle with a non-standard ground clearance based on the image information obtained in step (1) and the above-described minimum ground clearance determination reference information, and gives a display command of a result of the determination to the display unit 23; And a ROM 29 for storing the processing procedure of the non-minimum-height-standard vehicle discriminating means 28 in the form of a program.

More specifically, the minimum ground clearance non-standard vehicle discriminating means 28 determines the substantial minimum ground clearance of the vehicle 2 based on the output (binary image information) of the image processing device 22 and the discrimination exclusion information. Minimum ground clearance acquisition means 28a for finding height
And a comparison determination means 28b for comparing the minimum ground clearance obtained by the minimum ground clearance acquisition means 28a with the reference minimum ground clearance to determine a vehicle with a minimum ground clearance non-standard, so as to achieve the same function. It is configured.

Next, the processing procedure of the non-minimum-height standard discriminating means 28 executed in accordance with the program written in the ROM 29 will be described with reference to the flowchart shown in FIG.

First, in step 1 (S1), the process waits for the vehicle 2 to enter the storage area 3, and when it is detected by the opening operation of the storage gate 24 that the vehicle 2 has entered the storage area 3, step 2 ( In S2), the line sensor camera 21 captures an image of the passing vehicle 2.

In step 3 (S3), the image processing device 2
In step 2, image information captured by the line sensor camera 21 is binarized. Based on the binarized image information, the minimum ground clearance non-standard vehicle discriminating means 28 determines a semicircular shape (discrimination exclusion information) in contact with the ground contact surface 25 on the wheels 2a, 2b. And within a predetermined range from the wheels 2a and 2b (discrimination exclusion information).
Indicates that even if there is a protrusion, it is excluded from the determination as mudguard. Further, the width of, for example, all the scanning lines of the binary image information continuous in the moving direction is measured, and this measured value is compared with a predetermined value (the determination exclusion information If the measured value is smaller than a predetermined value, it is excluded from the discrimination as ground, water splash of the vehicle 2 in rainy weather, etc., and if the measured value is larger, the wheel contact surface 2
Measure the height from 5. Thus, the actual minimum ground clearance of the vehicle 2 excluding mudguard, grounding, and splashing of the vehicle 2 in rainy weather is obtained.

Instead of measuring the width of the binarized image information, an area measurement for counting the number of pixels or the number of clock pulses included in the binarized image information may be performed.
When the vehicle 2 does not move at a constant speed, it is possible to correct the speed of the image information based on the obtained image information to obtain accurate image information. Processing.

After the correct minimum ground clearance of the vehicle 2 is obtained in this way, in step 4 (S4), the minimum ground clearance is compared with the reference minimum ground clearance, and the minimum ground clearance is determined to be higher than the reference minimum ground clearance. If it is larger, it is determined that the vehicle is the minimum height standard vehicle, and in step 5 (S5), the display 2
3 is displayed as “Received OK”. As a result, the vehicle with the minimum ground clearance is immediately carried into the parking device 1.

On the other hand, in step 4 (S4), if the minimum ground clearance is equal to or smaller than the reference minimum ground clearance, it is determined that the vehicle is a vehicle with a minimum ground clearance that is not specified.
The display 23 displays “Receiving NG”. As a result, the vehicle with a minimum clearance above the ground clearance can be moved to the open exit gate 30
(See FIGS. 2 and 3), the driver is immediately moved out of the parking device 1 by driving of the driver.

As described above, in the present embodiment, it is determined whether or not the vehicle is a vehicle that does not meet the minimum ground clearance by using the image information obtained by imaging. That is, when the speed of the passing vehicle 2 fluctuates, the speed-corrected accurate image information is used. Based on the accurate image information, for example, ground,
Water droplets, mudguards, etc. of the vehicle 2 in the rainy weather are excluded from the determination, and the vehicle whose overall vehicle height is lower than the reference minimum ground clearance, the vehicle 2 having the substantial projection lower than the reference minimum ground clearance is the minimum. It has been identified as a non-standard vehicle. For this reason, it is possible to discriminate vehicles with minimum ground clearances with high accuracy.

In accordance with the display on the display 23 indicating that the vehicle 2 is ordered to exit (prohibiting further entry into the parking device 1), the vehicle outside the minimum ground clearance is quickly exited. Is prevented from being jammed. Further, since the parking of the non-minimum-height standard vehicle in the parking device 1 is prevented, the mutual interference between the projecting portion of the parking device 1 and the projection of the non-minimum-height standard vehicle is prevented. And each other's breakage / damage is avoided.

Further, in such a mechanical multi-story parking device 1, since a large number of protrusions protruding from the wheel contact surface 25 exist as described in the related art, the function of the non-minimum-height standard vehicle detection device 20 is provided. Has been fully demonstrated.

As described above, the present invention has been specifically described based on the embodiment. However, the present invention is not limited to the above-described embodiment. Although the (CPU) 28 is provided outside the image processing device 22, it may be built in the image processing device 22, and may be used also as a central processing unit (CPU) of the image processing device 22.

In the above-described embodiment, the non-minimum-height vehicle discriminating means 28 is provided by the line sensor camera 21.
The minimum ground clearance of the vehicle 2 is obtained based on the image information obtained in the above, and the minimum ground clearance is compared with a reference minimum ground clearance to determine a vehicle with a minimum ground clearance outside the standard. If there is an image of a (low) vehicle portion located below a reference minimum ground clearance (minimum ground clearance determination information) other than the wheels 2a and 2b, the width or area of the image is measured, and this measured value and If the measured value is larger than the predetermined value by comparing with the set predetermined value (discrimination exclusion information as the minimum ground clearance discrimination information), it is not a mudguard, an earth, a vehicle splash in rainy weather, etc. Alternatively, the vehicle may be determined to be a vehicle with a ground clearance outside the minimum ground clearance standard, such as a vehicle having a vehicle height that is lower than the reference minimum ground clearance as a whole, a vehicle having a substantial protrusion lower than the reference minimum ground clearance.

In the above-described embodiment, the line sensor camera 21 is used as the image pickup device, assuming that the vehicle detection device 20 outside the minimum ground clearance can be configured at lower cost. However, a television camera or the like may be used.

In the above embodiment, the imaging device 21 is installed in the parking area 3 of the parking device 1, but may be installed at the vehicle entrance of the parking device 1.

In the above-described embodiment, the non-minimum-height vehicle detection device 20 is connected to the entry area 3 and the exit area 9.
And the lift 7a and the lift 7b are applied to separate mechanical multi-story parking devices 1, but have a storage area that also serves as the storage area 3 and the storage area 9, and Of course, the present invention can also be applied to a mechanical multi-story parking device having a loading / unloading lift that also serves as a loading / unloading lift 7a and a loading / unloading lift 7b.

The minimum ground clearance non-standard vehicle detection device 20
Is applied to the mechanical multi-story parking device 1 as it can exhibit its function sufficiently, but it is of course applicable to other parking facilities, and furthermore, the parking for stopping the vehicle 2 in a predetermined area. The present invention can be similarly applied to a ship, an aircraft, a train, or the like that has an area and transports the vehicle 2 to another place. In short, the area protrudes from the wheel contact surface 25 into an area where the vehicle 2 enters. The present invention is applicable to all equipment having a protrusion.
