Title:
METHOD OF RECOGNITION OF STEREOSCOPIC IMAGE
Document Type and Number:
WIPO Patent Application WO/1993/021594
Kind Code:
A1
Abstract:
This invention relates to a technical field of computer stereovision. To recognize a stereoscopic image, the present invention relates to a novel method of interpretation and description of stereoscopic profile data of a certain article obtained from two directions through sensors. To accomplish this object, the present invention postulates that the stereoscopic image is constituted in such a manner that a certain cut plane of the object article is expressed by a disk assumed as a specific portion of a specific sphere which is in turn assumed to exist inside this article. On the basis of this assumption, the present invention utilizes the characteristics of the sphere and disk, sets and interprets the relation of correspondence between the two profile data, and describes the object article in the form of an aggregate of disks defined completely in the space coordinates. The present invention can be applied to apparatus for recognizing, restoring and inspecting stereoscopic images. Particularly because only the data on the profile line of the object article is necessary for the input signal, pre-processing is easy. Therefore, the present invention has the advantage that its application is easy.
