Abstract: Visual sensors are widelyused in SLAM(Simultaneous Localization and Mapping)technology.Multi-sensor fusionhas becomeanimportantresearch direction inrobotic SLAM.Accuratedataof visual extrinsic parameters directlyfects the successateofSAM.However,inpractice,extrinsicpaametercalirationoftencotaiserors,andsnsorsandeuipmet mayshift or deform duringlong-termuse,leading tochanges inthe extrinsic parameters.Meanwhile,calibration methods using calibration plates becomedificult when non-overlapping feldsofviewexist betweenmultiplecameras.This paper studies the calibrationofdual-Kinectdepthcameras,andutilzespointfeature matchingrelationshipstocalculatetherelativetransforation betweenthe two sensors,therebyobtaining the extrinsic parametercalibrationresults forboth cameras.Experimentalresults showthat inenvironments rich intexture information,theproposedcamera self-calibration method yieldsresults consistent with Zhang'scabrationmethod.Moreover,itenablesutonomouscalibationfersonvenientapplicationndcaneetthe demands of practical use.
