With the professional software for point cloud data processing and automatic texture mapping of digital images acquired by drones, the real 3D model of the survey area can be quickly established.
The study area is a building with a length of about 34 meters, a width of about 12 meters and a height of about 17 meters.
Its appearance is shown in Figure 1:
Figure 1 Overall appearance of the survey area
The UAV and the ground 3D laser scanner were used to collect data from the house, and the data of the point cloud in all directions was obtained. The 3DReshaper software is used to integrate and register the point cloud data acquired by the two methods, and after denoising and filtering, the point cloud data of the measurement area is obtained.
as shown in picture 2:

3D modeling and automatic texture mapping
Using the powerful modeling capabilities of 3DReshaper software, a 3D model of the survey area was built.
As shown in Figure 3:

Import the digital photos taken by the drone into the 3DReshaper, complete the batch mapping in the automatic texture mapping module, and adjust the model texture according to different photos.
The operation process is shown in Figure 4, and the mapped model is shown in Figure 5:
Figure 4 shows the texture mapping process of the house automatically

Multi-rotor UAV system for automatic route planning and automatic photographing, combined with ground scan data, modeled by 3DReshaper, its model can be used for planning display, generating orthophotos, etc., and can also achieve local high-precision modeling and precision control. As a professional point cloud processing and modeling and mapping software, 3DReshaper fully demonstrates its advantages when dealing with data combined with drones and ground scanners. Using 3DReshaper software to automatically map the 3D model, compared with the manual mapping method, avoiding the mouse click error when selecting the reference point, thus avoiding the texture offset and deformation, making the model texture more realistic and more accurate. high.
Automatic texture mapping of drone scan data based on 3DReshaper
As an emerging surveying and mapping method, drones are widely used in aerial photography of reservoirs, dams, reservoir areas and other places because of their light size, high operating efficiency and large data acquisition. The drone solves the problem of blind spots in the high angle of view, and the operation flow is simple and efficient. By adopting a high-altitude overhead image acquisition method for a specified route, it is possible to quickly extract two-dimensional vector data of the work area, a three-dimensional point cloud, and a rapid generation of a three-dimensional model. The data acquisition of the survey area is carried out by the unmanned aerial vehicle combined with the ground scanner, so that the data of the survey area can be quickly obtained.
