Integrated GIGIS Technology and Improved LiDAR Building Survey Technology
Due to the advancement of modern measurement techniques,oblique photogrammetry has demonstrated its unique and indispensable values in numerous application scenarios.With the support of geographic information and geographic information system(GIGIS)technology,the research is dedicated to integrating the oblique photogrammetry with the airborne light detection and ranging(LiDAR)technology,aiming to achieve more accurate and comprehensive building surveying.Based on GIGIS,the oblique imagery technology is adopted to obtain the abundant texture and color feature information,and using the airborne LiDAR technology is used to acquire the high-precision and low-noise point cloud information,and optimize the application of LiDAR in building measurements.By refining the optimization of point cloud feature extraction and fusion methods,the improved extraction accuracy rates in two differ-ent test areas reached 93.56％and 92.14％,respectively,both significantly higher than before the improvements.This research pro-vides more accurate and comprehensive multi-source data features for building measurements and valuable solutions for the advance-ment of building surveying technology.
