How Stereo Cameras Work and Key Products — ZED 2i, Subaru EyeSight
A stereo camera triangulates distance from the disparity between two lenses, solving the absolute-scale problem that fundamentally limits monocular cameras. We look at real specs from the Stereolabs ZED 2i, Luxonis OAK-D, and e-con Systems TARA, and trace the baseline-length tradeoff through the evolution of Subaru's EyeSight, which has shipped on over 5 million vehicles since 2008 — plus the story of how EyeSight's creator left Subaru to found his own stereo-vision startup.
