REGISTRATION OF STREET-LEVEL IMAGERY TO 3D BUILDING MODELS

摘要

POINT OF ORIGIN INFORMATION FOR IMAGE DATA MAY BE INACCURATELY REGISTERED AGAINST A GEOGRAPHIC LOCATION ABSOLUTE.A PROCESS FOR ALIGNING IMAGE AND HIGHLY ACCURATE MODEL DATA ADJUSTS A POINT OF ORIGIN OF THE IMAGE DATA BY MATCHING ELEMENTS IN THE IMAGE WITH CORRESPONDING ELEMENTS OF THE MODEL.IN A STREET (402)-LEVEL IMAGE, BUILDING SKYLINES CAN BE EXTRACTED AND CORRESPONDING SKYLINES FROM THE BUILDING MODEL CAN BE PLACED OVER THE IMAGE-BASED SKYLINE (516).BY ADJUSTING THE POINT OF ORIGIN OF THE IMAGE, THE RESPECTIVE SKYLINES CAN BE ALIGNED. BUILDING (504) EDGE (912) AND FACADE DEPTH (910) INFORMATION CAN SIMILARLY BE MATCHED BY ADJUSTING THE IMAGE POINT OF ORIGIN OF THE IMAGE.THE ADJUSTED POINT OF ORIGIN OF THE IMAGE CAN BE USED TO THEN AUTOMATICALLY PLACE IMAGES ON THE MODELS FOR A LONG RUN OF IMAGES.
