1. A multi-image capture device capturing images by means of circular motion, comprising: a carrier mechanism, comprising: a support frame; and a measuring rod, of semi-circular shape, wherein a fixture base is provided at a center of the measuring rod; the center of the measuring center connects to the support frame; and the fixture base is used to sustain a first image capture device; and two moving mechanisms, wherein the moving mechanisms are respectively mounted on the measuring rod, with one being at a left side of the fixture base and the other at a right side of the fixture base, in a manner of being able to move along the measuring rod; at least one of the moving mechanisms further comprising: a moving base, consisting of a shell, two movable pulleys and a positioning pulley, wherein a right side and a left side of the shell respectively has a through hole; the movable pulleys are mounted inside a front of the shell; the positioning pulley is mounted inside a rear of the shell; the measuring rod penetrates through the through hole, and the moving base is driven respectively by the movable pulleys and the positioning pulley to the measuring rod at the right side and left side of the fixture base; a rotary mechanism, mounted at a front of the moving base and used to fix a second image capture device; a location control device, connecting to the positioning pulley to control the rotation of the positioning pulley so as to control shift movement along the measuring rod and positioning of the second image capture device fixed on the rotary mechanism; and a rotary control device, used to control the rotation of the rotary mechanism connecting to the location control device so as to control the image-capturing angle and positioning of the second image capture device fixed on the rotary mechanism; wherein with the control of positioning of shift movement and image-capturing angle of the second image capture device by the location control device and the rotary control device, the first image capture device and the second image capture device are of a co-circle configuration which the central optical axis of the first image capture device and the second image capture device overlap to form a center of a co-circle.
