Abstract:
1. A two-parallel-channel reflector (TPCR) with focal length and disparity control, assembled on an imaging device, so that the imaging device is capable of synchronously capturing a left side view image and a right side view image of a scene, the TPCR comprising: a left side imaging channel, constructed by a left side image inlet, a left side outward reflecting unit formed by a curved reflecting mirror, and a left side inward reflecting unit formed by a flat reflecting mirror, wherein an end of the left side imaging channel is connected to a central image inlet; a right side imaging channel, constructed by a right side image inlet, a right side outward reflecting unit formed by a curved reflecting mirror, and a right side inward reflecting unit formed by a flat reflecting mirror, wherein an end of the right side imaging channel is connected to the central image inlet; and a convex lens, assembled in the central image inlet; wherein the left side and the right side imaging channels are configured whereby the left side view image enters from the left side image inlet, arrives at the left side outward reflecting unit, is reflected in parallel to the left side inward reflecting unit, is reflected by the left side inward reflecting unit, passes through the convex lens, and enters the imaging device through the central image inlet, the right side view image enters from the right side image inlet, arrives at the right side outward reflecting unit, is reflected in parallel to the right side inward reflecting unit, is reflected by the right side inward reflecting unit, passes through the convex lens, and enters the imaging device through the central image inlet; and further wherein a parallel reflection path is defined for each of the left side view and right side view images reflected from the left side and right side outward reflecting units to the left side and right side inward reflecting units.
