Production practice and application of new basic surveying and mapping based on real scene 3D

Aug 28, 2023

In response to the requirements of the country to promote the construction of three-dimensional reality in China, Feiyan Remote Sensing has explored a full-chain service model of data acquisition, data processing and data application, and can produce a full series of mapping products including tilted three-dimensional models, monomer models, laser point clouds, DEM, DSM, TDOM and 1:500 topographic maps.

With the Feiyan Remote Sensing AIMS multimodal aerial camera, orthophoto, oblique image, laser point cloud and hyperspectral image can be obtained simultaneously in one flight. We can produce a full range of surveying and mapping products, which can greatly save costs and time compared with traditional fieldwork.

In terms of the production of realistic 3D models, based on self-developed data processing software, it can generate high-resolution realistic texture maps, and can automatically detect and remove debris and suspended objects in 3D models, making 3D model production efficient, accurate and realistic.

In DEM and DSM production, the production process of batch processing by point cloud classification algorithm and manual refinement is adopted, supplemented by the cross-verification of real 3D models and topographic map results.
