JAUE2020-044: A Study on the Building Plan Database Using UAV

Abstract

Spatial information provides very important criteria and basic information for decision making. The establishment of spatial imformation is very important, but it is difficult to reflect the latest information on the target site, and in the case of building space objects currently provided in Korea, the results are different based on the subjective judgment of the worker. In addition, it is often the case that data is provided in different forms of data are often provided. In this study, the shape of the building was identified using Point Cloud's Point data and the accuracy was analyzed based on the drawings of the existing building. As a result of the measurement, the minimum error was 0.02m (99.95%) and the maximum error was 1.29m (96.84%). In the future, it is expected that the utility will be high when building a database for each city.
