Abstract

Abstract: With the maturity of UAV technology, tilt photogrammetric data can effectively support real-world 3D display, geographic information data mining, et al, which has been widely used in tourism real-world geographic information digitization. In this paper, aiming at the problem of slow display of large data volume tilt photogrammetry data, the data lightweight processing technology is explored and verified. Taking the oblique photogrammetric data of Pingyao ancient city scenic spot in Shanxi Province obtained by flight as the source data, the source data are processed and analyzed by various technologies, and the efficiency of the data source before and after optimization is verified by Cesium platform. The optimized oblique photogrammetric data can greatly improve the browsing efficiency, among which pyramid level optimization technology can browse the oblique photogrammetric data. The speed of browsing increased the most, accounting for about 50%.

Key words: tilt photogrammetry data, lightweight processing, optimization, display efficiency, pyramid level
