Bài viết Nghiên cứu kết hợp công nghệ máy bay không người lái (UAV) và quét Laser mặt đất thành lập mô hình 3D cấp độ chi tiết cao (LoD 3) cho nhà cao tầng trong khu vực đô thị được nghiên cứu nhằm chứng minh cho việc sử dụng kết hợp giữa hai công nghệ UAV và TLS có thể tạo ra mô hình 3D công trình nhà cao tầng ở mức độ chi tiết LoD 3, độ chính xác đạt tới tỷ lệ 1: 500 cho các khu đô thị theo tiêu chuẩn hiện hành. | 24 Journal of Mining and Earth Sciences Vol. 63 Issue 4 2022 24 - 34 Combined use of Terrestrial Laser Scanning and UAV Photogrammetry in producing the LoD3 of 3D high building model Ha Thu Thi Le 1 Trung Van Nguyen 1 Lan Thi Pham 1 Son Si Tong 2 Long Huu Nguyen 3 On Dac Vo 4 1 Faculty of Geomatics and Land Administration Hanoi University of Mining and Geology Vietnam 2 University of Science and Technology of Hanoi Vietnam 3 Dong Thap University Vietnam 4 Company of Khanh Hoa province Architectre Construction Consultans Stock Vietnam ARTICLE INFO ABSTRACT Article history Both Unmanned Aerial Vehicles UAVs and Terrestrial Laser Scanners TLS Received 23rd Feb. 2022 are important techniques for surveying and mapping. UAV equipment is Accepted 27th June 2022 commonly used to collect 2D or 3D data acquisition. Meanwhile TLS Available online 31st Aug. 2022 equipment is used for obtaining only 3D data acquisition. However if both Keywords are integrated they were able to produce more accurate data. Multi-sensor 3D Model data fusion helps overcome the limitations of a single sensor and enables a complete 3D model for the structure and better object classification. This Terrestrial Laser Scanners study focuses on studying the combination of UAV and TLS technologies to TLS collect process data and create the complete point cloud between two point Unmanned Aerial Vehicles clouds of the high building in Ha Long city Quang Ninh province to establish UAV . a 3D model at LoD 3 detail level with high accuracy. FARO FOCUS3D X130 and DJI Phantom 4 RTK equipments were used to acquire the data in the field. The aerial and ground data were processed using FARO SCENE 2019 and Agisoft PhotoScan software respectively. The data integration process is done by converting both point clouds into the same coordinate system and then by aligning the same points of both points clouds in Cloud Compare. The result of this study is a 3D model at LoD 3 detail level of the high building based on the .
