Claim Text:
1. A stereo camera apparatus comprising: an image capturing device suitable for obtaining a stereo image, the image capturing device comprising a plurality of image capturing units; an optical axis controlling module coupled to the image capturing device; and a calculating module coupled to the image capturing device and the optical axis controlling module, wherein the calculating module calculates a calibration condition according to the stereo image, the optical axis controlling module adjusts directions of imaging optical axes of the image capturing units in the image capturing device according to the calibration condition, and after being adjusted by the optical axis controlling module, imaging optical axes of the image capturing units are aligned, the calibration condition is determined by an alignment step which comprises: performing an image alignment step to adjust size deviations and rollover deviations of images respectively captured by optical axis of the image capturing units until the size deviations and the rollover deviations are smaller than an image alignment threshold value and a deviation threshold value.
