Abstract
A 3D image capture method includes selecting a plurality of different pairs of image capture devices, of which distance errors relevant to an object are determined, the distance error being a distance between a measured position and a real position of the object; selecting a pair of image capture devices with a minimum distance error; and obtaining 3D information according to spacing and angles of view of the selected pair of image capture devices.
