Stereo camera
First Claim
1. A stereo camera comprising:
- a first vehicle-mounted camera comprising a first lens unit and a first image sensor configured to perform imaging via the first lens unit; and
a second vehicle-mounted camera comprising a second lens unit and a second image sensor configured to image via the second lens unit,wherein the first image sensor has a first sensitivity value memory in which a sensitivity value of the first image sensor is recorded,wherein the second image sensor has a second sensitivity value memory in which a sensitivity value of the second image sensor is recorded,wherein a sensitivity variation width between the sensitivity value of the first image sensor recorded in the first sensitivity value memory and the sensitivity value of the second image sensor recorded in the second sensitivity value memory is within a predetermined reference width, wherein the sensitivity values are transmittance values,wherein the first lens unit comprises a first optical information memory in which a sensitivity value of the first lens unit is recorded,wherein the second lens unit comprises a second optical information memory in which a sensitivity value of the second lens unit is recorded, andwherein whichever of the first image sensor and the second image sensor has a lower sensitivity value is combined with whichever of the first lens unit and the second lens unit has a higher sensitivity value.

Abstract
In order to obtain a low-cost stereo camera which can decrease the load of software-based calibration, a stereo camera is provided with a first vehicle-mounted camera which comprises a first lens unit and a first imaging element, and a second vehicle-mounted camera which comprises a second lens unit and a second imaging element. This stereo camera is characterized in that the first imaging element has a first sensitivity value recording unit in which sensitivity values of the first imaging element are recorded, and the second imaging element has a second sensitivity value recording unit in which sensitivity values of the second imaging element are recorded, wherein the sensitivity variation width between the sensitivity values of the first imaging element recorded in the first sensitivity value recording unit and the sensitivity values of the second imaging element recorded in the second sensitivity value recording unit is within a preset reference width.
