Claim Text:
1. A method of calibrating a stereoscopic imaging device, comprising: capturing a first image of a scene of interest with a first image sensor having a first resolution, a first set of intrinsic parameters and a first set of extrinsic parameters; capturing a second image of the scene of interest with a second image sensor having a second resolution different from the first resolution, wherein the second image sensor comprises a second set of intrinsic parameters and a second set of extrinsic parameters, and wherein the first image and second image comprise a stereoscopic image pair; determining a normalized focal distance of the first image sensor, based, at least in part, on the intrinsic and extrinsic parameters of the first sensor; adjusting a calibration matrix based on the normalized focal distance; and storing the calibration matrix in the stereoscopic imaging device.
