Abstract:Tomeet thedemandof buildinghigh-quality3Dmodelsforintellgentmobilerobots,a3DGausiansplatting (3DGS)optimizationalgorithmbasedonmulti-sensorfusionisproposedbasedon3DGaussiansplattingreconstruction technology.ThedatasetcontainingLiDAR,cameraandIMUinformationisrecordedintherealscene.The3DGausian distributionisinitializedbytheoptimizedodometerposeandthecamerafeaturepointscalibratedbythelaserpointcloud.On thebasisoftakingaccountofthegeometricinformationoftepointcloud,thelossfunctionisimprovedfortheparameterodel optimization.The3DGSoptimizationalgorithmbasedonmulti-sensorfusionandtheoriginal methodweresubjectedto reconstructionexperimentsunderdiferentdatasets.Thereconstructedresultswerecomparedintworealscenarios.The experimentalresultsshowthatthepeak signal-to-noiseratio(SNR)ofthe3DGausiansplattingoptimizationalgorihmbasedon multi-sensor fusion isimproved by 3.5% and 3% in weak texture environment and general texture environment respectively,in comparisonwiththe3DGSreconstructionmethod.Anditsstructural similarity(SSIM)andlearnedperceptualimagepatch similarity(LPIPS)alsoperformwell.Itcanbeseenthatthequalityof thereconstructedmodelhasbeenimprovedand the effectiveness of the proposed algorithm has been validated.
