Selfcalibration ofa roadstereo visionsystem through correlation criterions

In thisarticle, we adresstheproblemofself calibrating an embeddedstereoscopic vision system, thatis determining itsepipolar geometry automatically. After reviewing thegeneral method, wepropose anddescribe twonewmethods formatching points, basedoncorrelation, andusingthesole constraint ofunicity. We comparethemwithan already published method, andpresent someexperimental results. IndexTerms Stereovision, correlation, epipolar geometry, fundamental matrix
