Abstract

PURPOSE:To keep off any car-to-car contact accident or the like in a parking area by installing a parking space as wide as at least a portion for one vehicle and a camera for photographing the state of affairs around the periphery in the parking area, and displaying an image taken by this camera on a display at the vehicle side. CONSTITUTION:A camera unit 10 consisting of a camera 11 with CCD or the like and a transmitter 12 transmitting an image signal taken by this camera 11 with an empty channel different at each parking space, for example, ultra high frequency UHF is set up one by one at each position where at least one vehicle parking space exists and the peripheral circumstances are photographable from the upside, in a parking area. On the other hand, a receiver 21 and a car-mount monitor 22 are installed in a vehicle 20. Then, an image signal out of the transmitter 12 is received by the receiver 21 on the vehicle, displaying the image on the car-mounted monitor 22. A driver garages his car into a specified parking space as checking the whole positional relation-ship between his own vehicle and other vehicles displayed on the monitor 22.

Description

DETAILED DESCRIPTION OF THE INVENTION [Large aspects of the invention] (Field of industrial application) The present invention relates to a vehicle safety confirmation system used in various parking lots.

(Prior Art) In recent years, a vehicle safety confirmation method using an on-vehicle camera has been known as a method for smoothly and safely parking a vehicle in a parking lot.

For example, as shown in Figure 7, this uses a camera to capture images of the front, rear, and sides of the vehicle, which tend to be blind spots for the driver, and displays the images on the in-vehicle monitor. Kaisho 49-95333.54-7053

Publication No. 18, etc.).

However, with this method, if you want to check all of the vehicle's blind spots, it is necessary to attach a camera to the vehicle for each blind spot, and if there is only one in-vehicle monitor, the images captured by each camera can be switched and displayed. There are many issues such as whether it is necessary to do so.

Further, even if images captured by each camera could be displayed at once, it was difficult to grasp the overall position of the vehicle within the parking space and its positional relationship with surrounding objects.

(Problems to be Solved by the Invention) As described above, in the conventional vehicle safety confirmation system, it is difficult to grasp the overall position of the vehicle in the parking space and the positional relationship with surrounding objects.

The present invention is intended to solve these problems, and when parking in a parking lot, it is possible to check at a glance the position of the vehicle in the parking space and the positional relationship with surrounding objects. The purpose is to propose a vehicle safety confirmation system that can prevent collisions, etc.

[Configuration of the Invention (Means for Solving the Problems)] In order to achieve the above-mentioned object, the vehicle safety confirmation system of the present invention monitors a parking space for at least one vehicle and its surroundings from above in a parking lot. A camera for photographing an object and a transmitter for transmitting the image captured by this camera are installed, and a receiver for receiving the image from the transmitter and the image received by this receiver are displayed on the vehicle. It is characterized in that it is equipped with a display device.

(Function) In the vehicle safety confirmation system of the present invention, a camera installed in a parking lot captures an image of a vehicle entering a parking space from above, and transmits the image to the vehicle through a transmitter. The transmitted video signal is received by a receiver in the vehicle and displayed on a display device.

Therefore, according to the present invention, the position of the vehicle within the parking space and the positional relationship with surrounding objects can be confirmed at a glance, thereby making it possible to prevent collision accidents in the parking lot.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing the configuration of a vehicle safety confirmation system according to an embodiment of the present invention.

In the figure, ]0 is a camera unit installed in the parking lot. This camera unit]0 consists of a camera 11 using a CCD or the like, and a transmitter 12 that transmits the video signal captured by the camera 1 using an empty channel of, for example, IJHF, which is different for each parking space. As shown in FIGS. 2 and 3, this camera unit] 0 is located at a position where it can capture an image of at least one parking space for each parking space and its surroundings from above, such as a parking lot. One by one is installed on the ceiling of the building. Further, 2] and 22 are respectively vehicle 20
The video signal from the transmitter 12 is received by the receiver 21 of the vehicle, and the video is displayed on the vehicle monitor 22. In addition, near sunset in the parking lot or in each parking space, choose a position that is easily visible to the driver.
A board (not shown) is installed in each parking space on which the transmission and reception frequencies of video signals assigned to each parking space are displayed.

Next, the operation of this vehicle safety confirmation system will be explained.

In the parking lot, the driver first turns on the power of the receiver 21 and the in-vehicle monitor 22 in the vehicle 20, and then
Match the receiving frequency of No. 1 to the transmitting/receiving frequency assigned to the parking space you are about to use.

Note that various methods are selected for switching the power on/off of the camera unit 10 depending on the operation mode of the parking lot. For example, in the case of a large commercial parking lot such as a department store, it may be left on all day during business hours, the manager may switch it on for each parking space as necessary, or the sensor may detect vehicle intrusion and automatically turn on the parking lot. Examples include a method of switching. In addition, if the parking lot is privately owned, there is a method in which each driver himself/herself can turn on/off the power of the camera unit 10 using a remote JM operation.

FIG. 4 shows the transition of the image displayed on the in-vehicle monitor 22 when the vehicle is parked in the garage. Here 40 is your own vehicle,
4] is a vehicle parked in an adjacent parking space, and 42 is a line separating the parking spaces.

In this way, the driving name is based on the position of the own vehicle 40 within the parking space displayed on the in-vehicle monitor 22 and other vehicles 4]
Check the overall positional relationship with the vehicle before pulling into the desired parking space.

Thus, according to the vehicle safety confirmation system of this embodiment,
In the garage, own in the parking space! The position of the 11 cars or the positional relationship with surrounding objects can be confirmed by "-1", and it is possible to prevent accidents such as collisions when parking the vehicle in the garage, especially by inexperienced drivers.

In addition, in the case of a large commercial parking lot, the entrance to the parking lot is
A board displaying the numbers of vacant parking spaces and the transmission/reception frequencies of video signals may be installed near the parking lot.

In addition, in the above-described embodiment, one camera unit]0 was installed in each parking space, or as shown in FIG. The camera unit may be configured to be able to move back and forth across spaces, and in response to a call from any parking space, move the camera unit to a predetermined imaging position on the called parking space. good. In this case, the camera unit 0 may be called by remote control from inside the vehicle by the driver or by operation by the parking lot manager.

Furthermore, as shown in FIG. 6, the in-vehicle monitor 22 may perform image processing and display so that its own vehicle 60 is always placed in the center of the screen.

[Effects of the Invention] As explained above, according to the vehicle safety confirmation system of the present invention, when parking in a parking lot, the position of the own vehicle in the parking space and the positional relationship with surrounding objects can be determined by -11. This makes it possible to prevent collisions, etc. in the parking lot.
