Feiyan remote sensing real scene 3D project case

May 29, 2023

In the past two years, Feiyan Remote Sensing has successively undertaken the 3D construction of terrain-level, city-level, and component-level real-scenes in Jiangsu, Anhui, Hong Kong and other places over 10,000 square kilometers. In terms of personnel, Feiyan Remote Sensing has expanded the data processing team, with an annual data production capacity of 350,000 square kilometers; in terms of hardware, it is equipped with 15 workstations for air triangulation processing, 6 sets of storage servers are used for data storage, and 150 node computers are used for data preprocessing and model production; in terms of software, we have independently developed ImgTools raster data batch processing software, MapTools map framing software and 3D model coordinate conversion software, etc. The professional software realizes batch and automatic processing, which greatly improves the efficiency of data processing.

Wuhan New Basic Surveying and Mapping Project

The new basic surveying and mapping project in Wuhan is the first national new basic surveying and mapping pilot approved since the establishment of the Ministry of Natural Resources. Feiyan Remote Sensing undertakes oblique photography and terrain-level, city-level and component-level real scenes of about 616 square kilometers in the central city area of better than 0.03 meters 3D construction. Based on the pilot results, Wuhan has integrated a unified real-scene 3D space-time base, which has improved the level of urban management; using terrain-level and city-level real-scene 3D to dynamically simulate urban inundation conditions, formulate emergency plans for waterlogging prevention, and achieve remarkable results in information-based waterlogging prevention and control effectiveness.

High-precision Shangyu terrain scene construction project

Feiyan Remote Sensing adopts the self-developed AIMS aerial integrated multi-sensor aerial camera to obtain multi-modal data such as laser point cloud, oblique 3D, and hyperspectral at one time. The high-density laser point cloud of 50 points per square meter obtained by AIMS directly generates a white model, which avoids the lengthy data processing process and saves flight costs; DEM and white model are based on the same set of data, which is more suitable for the terrain and more efficient The range is improved, and the information contained in the location, height, shape and other information of the building provides key data for the analysis and processing of 3D data.

multi-source data

Real scene 3D project in Xinwu District, Wuxi City

The real-scene 3D project of Xinwu District, Wuxi City is the first 3D geographic information service project covering the whole district in Wuxi. Feiyan Remote Sensing undertakes the oblique aerial photography and real-scene 3D model update of 220 square kilometers in Xinwu District with a resolution better than 5 cm And geographic information application platform development. Make full use of the inclined 3D model of Xinwu District and relevant land data, and use 3D GIS, Internet of Things, cloud computing and other technologies to develop a B/S version of geographic information application platform. The platform integrates multi-source data visualization management, spatial analysis tools, land information management and other capabilities. The interconnection and integrated application of information resources can comprehensively improve the geographic information service level of user units.
