A stereo camera apparatus, and a vehicle provided with a stereo camera apparatus, can detect an object targeted for detection in a wider spatial range, calculate the distance to a subject with high accuracy, and perform object detection with high accuracy. The stereo camera apparatus (1) includes a first imaging unit (2), a second imaging unit (3) that images an area partially shifted from an area imaged by the first imaging unit (2) in a direction differing from a direction along the baseline length, and a controller (4) that calculates the distance to a subject using an overlapping region between a first image captured by the first imaging unit (2) and a second image captured by the second imaging unit (3).
