Method for examining shooting direction of camera apparatus, device thereof and structure for installing sensor
View Patent ↗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.
1. 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 and is adjusted by replacing said mounting member with another mounting member having a different shape.
2. The structure for mounting the onboard sensor according to claim 1 , wherein said mounting member is a plate-like member and the monitoring direction of said sensor is determined by a state of the thickness of said mounting member.
3. The structure for mounting the onboard sensor according to claim 2 , wherein said mounting member has a tapered shape in cross section along a longitudinal direction of the vehicle, and the vertical component of the monitoring direction of said sensor is determined by said tapered shape.
4. The structure for mounting the onboard sensor according to claim 1 , wherein a contact surface between said mounting member and said sensor assembly disagrees the horizontal plane under conditions where said sensor is attached to the vehicle body.
5. The structure for mounting the onboard sensor according to claim 1 , wherein comprising:
a fixing member for fixing said sensor assembly to the vehicle body;
wherein said mounting member is independent of said sensor assembly when said fixing member is removed under conditions where said sensor assembly is fixed to the vehicle body.
6. The structure for mounting the onboard sensor according to claim 1 , wherein said mounting member is replaced with another mounting member having a slightly different shape; and
each mounting member is marked with an identification mark indicating features of shape of said mounting member.
7. The structure for mounting the onboard sensor according to claim 6 , wherein a location of said identification mark is placed is an externally unascertainable location under conditions where said sensor is attached to the vehicle body.
8. The structure for mounting the onboard sensor according to claim 1 , wherein said sensor assembly is a stereo camera assembly.
9. 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 and is adjusted by replacing said mounting member with another mounting member having a different shape.
