Description
Summary:A robust 3D image measurement method is proposed in order to suppress occlusion by a quasi multi‐baseline‐stereo method based on a single camera configuration. There is no way to suppress completely the “occlusion problem” in the field of stereo geometry. In order to deal with this problem, the multi‐baseline‐stereo configuration is often adopted and is basically effective. This paper proposes a new configuration for stereo measurement by means of a single camera, a mechanical feeder for the object, image processing for the baseline calibration, and in particular, diagonal feeding of the object in front of the camera. The concept of this method is to realize a pair of stereo geometries in the stereo configuration with a single camera and a mechanical feeder. It is technically noted that the baseline of this single camera stereo was precisely calibrated by an image processing procedure in both the horizontal and vertical directions. © 2009 Wiley Periodicals, Inc.
