Technical characteristics of oblique photography

Feature 1: Reflect the real situation around the feature.

Compared with orthographic images, oblique images allow users to observe ground objects from multiple angles, and reflect the actual situation of ground objects more truly, which greatly makes up for the shortcomings of application based on orthographic images.

Feature 2: Inclined image can measure a single image.

Through the application of supporting software, the height, length, area, angle and slope can be measured directly based on the result image, which expands the application of oblique photography technology in the industry.

Feature 3: you can collect the texture of the side of the building.

Aiming at various 3D digital city applications, the cost of 3D city modeling can be effectively reduced by taking advantage of the characteristics of large-scale mapping by aerial photography and adopting the methods of batch extraction of oblique images and texture pasting.

Feature 4: The amount of data is small and easy to publish on the Internet.

Compared with the huge 3D data applied by 3D GIS technology, the image data obtained by oblique photography technology is much smaller. With mature technology, the image data format can be quickly released to the network, thus realizing * * *.
