JPH1081209A - Vehicle bottom face inspecting method and device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make any foreign substances or the like surely inspectable in taking them as a projected image easily and accurately by guiding an image pickup camera on the bottom face of a vehicle, and seeing the bottom image through a monitor. SOLUTION: An image pickup camera 2 and an illuminating part 3 both are installed in a casing 1, while a lens 2a of the camera 2 is situated on a top face 1a, and an optical axis of this lens 2a goes straight in the facial direction, turning it upward. Plural pieces of roller-type casters 4 are installed on a bottom face 1b, making up them so as to be freely travelable on the ground. A forked handle 7 being formed in the end of a connecting rod 6 is operated, and the casing 1 is guided to the bottom face of a vehicle and the illuminating part 3 is lighted, so the l>:>ttan face is reflected and revealed on a monitor 8. Since it goes through the wide angle lens 2a, the image on the bottom face is clearly securable and, what is more picture recording is easily performable as well.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for inspecting a bottom surface of a vehicle, and more particularly, to a method of guiding an imaging camera under a bottom surface of a vehicle and viewing an image of the bottom surface on a monitor to easily and clearly determine the state of the bottom surface. To see new improvements.

[0002]

2. Description of the Related Art Conventionally, as a method of inspecting the bottom of a vehicle of this type, a mirror provided at the tip of a handle is guided under the bottom of the vehicle, and the state of the bottom is inspected through the mirror. He had been visually inspected.

[0003]

The conventional method for inspecting the bottom surface of a vehicle has the following problems because it is configured as described above. That is, when viewing with a mirror, a human had to look into the mirror, and when it was dark, or when the mirror was dirty, the work was extremely difficult. In addition, the content of the autopsy cannot be recorded as an image, and it is difficult to obtain evidence.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. In particular, the present invention guides an imaging camera below the bottom of a vehicle and views an image of the bottom on a monitor, thereby facilitating the state of the bottom. It is another object of the present invention to provide a method and an apparatus for inspecting a vehicle bottom surface which can be seen clearly.

[0005]

The method of inspecting a vehicle bottom surface according to the present invention is a method of guiding an imaging camera below a bottom surface of a vehicle and recognizing an image of the bottom surface obtained by the imaging camera on a monitor.

More specifically, there is a method of recording an image obtained on the monitor.

A vehicle bottom surface inspection apparatus according to the present invention includes an imaging camera provided on a casing, and a monitor for viewing an image from the imaging camera, and a lens of the imaging camera is provided on an upper surface of the casing. Configuration.

More specifically, a caster is provided on the bottom surface of the casing, and the casing is movable by the casters.

[0009] More specifically, the casing is provided with a lighting unit.

[0010] More specifically, the casing and the monitor are connected by a connecting rod, and the connecting rod is provided with a handle.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the method and apparatus for inspecting a vehicle bottom surface according to the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a casing whose overall shape is a square box.
Includes an imaging camera 2 such as a CCD camera and an illumination unit 3
The lens 2a of the imaging camera 2 is located on the upper surface 1a of the casing 1, and the optical axis of the lens 2a is directed upward at right angles to the surface direction of the upper surface 1a.

A plurality of roller-type casters 4 are provided on the bottom surface 1b of the casing 1, and the casing 1 is configured to be able to move freely on the ground below the bottom surface of a vehicle (not shown). An elongated connecting rod 6 is pivotally supported on a hinge 5 provided at one end of the casing 1, and a forked handle 7 is formed at an end of the connecting rod 6. Is provided with a monitor 8 having a built-in VTR. The imaging camera 2 and the monitor 8 are connected to a cable 9
, And a power cable 10 is connected to the monitor 8.

Next, the operation will be described. First, Toride 7
Is operated to guide the casing 1 under the bottom surface of the vehicle and turn on the illumination unit 3, and this bottom surface is projected and appears on the monitor 8. Accordingly, by moving the casing 1 through the casters 4, the operator can obtain a clear image of the bottom surface through the wide-angle lens 2a, and can easily perform recording. In the above-described embodiment, the casing 1 and the monitor 8 are connected by the connecting rods 6. However, for example, the casing 1 and the monitor 8 may be separately provided, and the casing 1 may be moved by a remote controller.

[0014]

The method and apparatus for inspecting the bottom surface of a vehicle according to the present invention are configured as described above, so that the following effects can be obtained. That is, the bottom surface of the vehicle can be easily and reliably captured as an image by the imaging camera provided on the movable casing, and the inspection of foreign substances and the like can be performed reliably.
