Method for examining shooting direction of camera apparatus, device thereof and structure for installing sensor
First Claim
1. A test method for examining a shooting direction of a camera apparatus by comparing a position of a reference pattern and a position of a judgment pattern on a displayed photographed image so as to judge if said shooting direction is adjustable by a first adjuster, wherein said shooting direction is adjustable by a second adjuster, and a first adjustable range by said first adjuster is smaller than a second adjustable range by said second adjuster, comprising:
- photographing with said camera apparatus a test chart placed at a predefined position ahead of said camera apparatus with a reference pattern drawn on the test chart, the photographing producing a photographed image;
setting a judgment pattern at a specific position on said photographed image, said judgment pattern represents said first adjustable range; and
displaying said photographed image including said reference pattern with said judgment pattern on a display device;
judging whether said reference pattern is within said judgment pattern; and
notifying of information concerning adjustment of said shooting direction by said second adjuster in the case where said reference pattern deviates from said judgment pattern.

Abstract
In a test method in which an image photographed by a camera apparatus 1 attached to a body of a vehicle is displayed on a display device 17 and an examiner examines compliance or non-compliance of the shooting direction of the camera apparatus 1 by comparing the position of a reference pattern and the position of a judgment pattern on the displayed photographed image, the photographed image is obtained at first by photographing with the camera apparatus 1 a test chart which is placed at a predefined position ahead of the vehicle with the reference pattern drawn on the test chart. Next, the judgment pattern is set at a specific position on the photographed image. Then, the photographed image on which the judgment pattern has been set is displayed on the display device 17.

16. A test method for examining whether a shooting direction of a camera apparatus attached to a body of a vehicle is within a finely adjustable range which is an adjustable range by an image transformation, wherein said shooting direction is adjustable by a mounting adjuster of said camera apparatus, and said finely adjustable range is smaller than a mounting adjustable range by said mounting adjuster, comprising:
-
obtaining a photographed image by photographing with said camera apparatus a test chart placed at a predefined position ahead of the vehicle with a reference pattern drawn on the test chart; determining a position of said reference pattern on said photographed image; judging on compliance or non-compliance of the shooting direction of said camera apparatus based on a relationship between the position of said reference pattern determined and a proper range defining a finely adjustable range which is an adjustable range by said image transformation for the shooting direction of said camera apparatus; and notifying of information concerning adjustment of said shooting direction by said mounting adjuster in the case where said reference pattern deviates from said proper range. - View Dependent Claims (17, 18, 19, 20)

21. A test method for examining the shooting direction of the camera apparatus attached to a body of a vehicle, comprising:
-
obtaining a photographed image by photographing with said camera apparatus a test chart placed at a predefined position ahead of the vehicle with a reference pattern drawn on the test chart; determining a position of said reference pattern on said photographed image; judging on compliance or non-compliance of the shooting direction of said camera apparatus based on a relationship between the position of said reference pattern determined and a proper range defining a range appropriate for the shooting direction of said camera apparatus; notifying an examiner of information concerning current mounting conditions of said camera apparatus or information concerning adjustment of the mounting of said camera apparatus according to the amount of deviation of said reference pattern when said reference pattern deviates from said proper range, wherein camera apparatus is attached to the vehicle body via a replaceable mounting member and the shooting direction of said camera apparatus is determined by the shape of said mounting member; and said notifying step includes;
selecting a mounting member having a shape for minimizing the amount of deviation of said reference pattern from a plurality of previously prepared mounting members having different shapes; and
notifying the examiner of said selected mounting member.

22. A test method for examining a shooting direction of a camera apparatus to judge whether or not the camera apparatus can be positioned within a finely adjustable range which is adjusted by an image transformation with respect to the deviation of a camera position, wherein said shooting direction is adjustable by a mounting adjuster of said camera apparatus, and said finely adjustable range is smaller than a mounting adjustable range by said mounting adjuster, comprising:
-
obtaining a photographed image by photographing with said camera apparatus a test chart placed at a predefined position ahead of said camera apparatus with a reference pattern drawn on the test chart; setting a judgment pattern at a specific position on said photographed image, said judgment pattern represents said finely adjustable range; displaying said photographed image with said judgment pattern on a display device; and examining compliance or non-compliance of the shooting direction of said camera apparatus by comparing a position of said reference pattern and a position of said judgment pattern on said displayed photographed image; and notifying of information concerning adjustment of said shooting direction by said mounting adjuster in the case where said reference pattern deviates from said proper range. - View Dependent Claims (23, 24)

25. A test method for examining a shooting direction of a camera apparatus comprising:
-
photographing with said camera apparatus a test chart placed at a predefined position ahead of said camera apparatus with a reference pattern drawing on the test chart, and producing a photographed image of said reference pattern; setting a judgment pattern at a specific position on said photographed image, said judgment pattern representing a first adjustable range; comparing a position of the reference pattern and a position of the judgment pattern on the photographed image so as to judge if said shooting direction is adjustable by a first adjuster, wherein said shooting direction is adjustable to a second adjustable range by a second adjuster, and the first adjustable range is smaller than a second adjustable range, displaying said photographed image including said reference pattern with said judgment pattern on a display device; judging whether said reference pattern is within said judgment pattern; and notifying of information concerning adjustment of said shooting direction by said second adjuster in the case where said reference pattern deviates from said judgment pattern.
