Camera mount assembly for incremental angle meaurement in three axes

A method for imaging an object, comprising:

• coupling a camera mount assembly to a support structure, the camera mount assembly holding a camera or other perception sensor, the camera mount assembly comprising:
• a base structure adapted to be coupled to the support structure;
• a first rotational adjustment mechanism coupled to the base structure and adapted to rotate the camera or other perception sensor with respect to the base structure about a first axis;
• a second rotational adjustment mechanism coupled to the first rotational adjustment mechanism and adapted to rotate the camera or other perception sensor with respect to the base structure about a second axis that is perpendicular to the first axis;
• and
• a third rotational adjustment mechanism coupled to the second rotational adjustment mechanism and adapted to rotate the camera or other perception sensor with respect to the base structure about a third axis that is perpendicular to the second axis;
• aligning the base structure of the camera mount assembly with respect to a ground plane;
• adjusting and recording an orientation of the camera or other perception sensor using one or more of the first rotational adjustment mechanism, the second rotational adjustment mechanism, and the third rotational adjustment mechanism of the camera mount assembly;
• imaging the object using the camera or other perception sensor;
• and
• determining an orientation of the object with respect to the orientation/a position of the camera or other perception sensor using the recorded orientation of the camera or other perception sensor relative to the ground plane.

A method for training a driver assist or autonomous driving system using an imaged object, comprising:

• coupling a camera mount assembly to a support structure, the camera mount assembly holding a camera or other perception sensor, the camera mount assembly comprising:

• and
• providing the imaged object to the driver assist or autonomous driving system.
