What is the essence of three-dimensional model of UAV tilt photography?

It is essentially composed of photos from multiple angles. Photos are imported into modeling software, and point clouds are generated through computer graphic calculation and pos information space processing. Point clouds form a grid, and the grid is combined with photos to generate a textured three-dimensional model.

Advantages of UAV tilt photography technology;

1, which breaks through the limitation that the traditional aerial camera can only shoot orthographic images from a vertical angle, and can obtain more comprehensive texture details of ground objects and reflect the actual situation of ground objects more truly.

2. Terrain mapping is carried out by UAV equipped with tilt camera, and the automatic image matching and modeling system can reduce manual intervention and improve work efficiency.

3. It can greatly shorten the collaborative work in the field of surveying and mapping, save the labor time of surveying and mapping personnel and reduce the labor intensity in the field.

4. Oblique images can provide users with rich geographic information products, realize the superimposed display of two-dimensional and three-dimensional data, and provide auxiliary decision analysis for related cadastral management information systems.
