Abstract
A camera and production technique for an ADAS. The camera lens and image sensor are positioned along multiple axes using a target located at a first distance from the lens to establish a first relative position between the lens and the image sensor. The first relative position between the lens and the image sensor is modified by a predetermined amount for an object located a second distance from the lens. The second distance is larger than the first distance.

(canceled)
A camera comprising:
- a lens with a radial distortion;
- an image sensor with a plane of sensors;
- and
- a housing to maintain a position between the lens and the image sensor, wherein the position is based on:
- an arrangement of the lens and the image sensor based on the radial distortion;
- an alignment of the lens to the image sensor to focus on a target;
- and
- an adjustment of a distance between the lens and the image sensor, along an axis perpendicular to the plane of the image sensor, by a predetermined amount following the alignment, the adjustment to focus the lens and the image sensor at infinity.
A method comprising:
- arranging a lens and an image sensor based on a radial distortion of the lens;
- aligning the lens to the image sensor to focus on a target;
- and
- adjusting a distance between the lens and the image sensor, along an axis perpendicular to a plane of the image sensor, by a predetermined amount following alignment to focus the lens and the image sensor at infinity.
At least one machine readable medium including instructions that, when executed by a computer, cause the computer to perform operations comprising:
- arranging a lens and an image sensor based on a radial distortion of the lens;
- aligning the lens to the image sensor to focus on a target;
- and
- adjusting a distance between the lens and the image sensor, along an axis perpendicular to a plane of the image sensor, by a predetermined amount following alignment to focus the lens and the image sensor at infinity.
