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.

11. A test device for examining the shooting direction of a camera apparatus installed on a vehicle, comprising:
-
a camera apparatus attached to a body of the vehicle and outputs a photographed image by photographing a situation ahead of the vehicle;
processing unit for superimposing a specific judgment pattern on a specific position of said photographed image; and
display device for displaying said photographed image, wherein said camera apparatus photographs a test chart placed at a predefined position ahead of the vehicle with a specific reference pattern drawn on the test chart during a test;
said processing unit performs the superimposition operation on said photographed image during the test; and
said display device displays the position of said reference pattern on said photographed image and the position of said judgment pattern in a manner that they are compared with each other during the test. - View Dependent Claims (12, 13, 17, 21)

14. A test device for examining the shooting direction of an onboard camera apparatus attached to a body of a vehicle, comprising:
-
a camera apparatus attached to the vehicle body and outputting a photographed image by photographing a situation ahead of the vehicle; and
test unit for examining the shooting direction of said camera apparatus based on a photographed image obtained by photographing with said camera apparatus a test chart placed at a predefined position ahead of the vehicle with a specific reference pattern drawn on the test chart during a test;
wherein said test unit determines the position of said reference pattern on said photographed image, and wherein said test unit judges that the shooting direction of said camera apparatus is proper when the position of said reference pattern determined falls within a proper range defining a range appropriate for the shooting direction of said camera apparatus, and said test unit judges that the shooting direction of said camera apparatus is improper when the position of said reference pattern falls outside said proper range. - View Dependent Claims (15, 16, 18, 19, 20)

22. A structure for mounting an onboard sensor, comprising:
-
a sensor for monitoring traffic conditions ahead of a vehicle;
a sensor assembly for assembling said sensor; and
a mounting member formed independently of said sensor assembly, wherein said sensor assembly is attached to a vehicle body via said mounting member, and a monitoring direction of said sensor is determined based on the shape of said mounting member. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)

23. A structure for mounting an onboard sensor, comprising:
-
a mounting member;
a sensor assembly attached to a vehicle body via said mounting member; and
a sensor for monitoring traffic conditions ahead of the vehicle, said sensor being assembled into said sensor assembly, wherein said mounting member is replaced by removing said sensor assembly, and a monitoring direction of said sensor is determined based on the shape of said mounting member.
