Features of Oblique Photography

May 17, 2023

The birth of oblique photography technology has subverted the traditional way of operation. By carrying 5 sensors on the same flight platform, images are collected from one vertical, four oblique, and five different angles at the same time. Oblique images are analyzed and organized.

Oblique photography technology has the following three characteristics:

(1) Reflect the real situation of the ground features and can measure the ground features

The three-dimensional data obtained by oblique photogrammetry can truly reflect the appearance, position, height and other attributes of ground objects, which enhances the sense of reality brought by three-dimensional data and makes up for the shortcomings of traditional artificial models with low simulation degree. Enhanced application of oblique photography techniques.

(2) High cost performance

Oblique photogrammetry data is measurable image data with spatial position information, and can output data results such as DSM, DOM, and DLG at the same time. It can obtain more data while satisfying traditional aerial photogrammetry. At the same time, the method of batch extraction and texture pasting of oblique images can effectively reduce the cost of urban 3D modeling.

(3) High efficiency

Oblique photogrammetry technology can quickly collect image data with the help of flying carriers such as drones, and realize fully automated 3D modeling. Experimental data proves that 1-2 years of artificial modeling of small and medium-sized cities can be completed in 3-5 months with the help of oblique photogrammetry technology.
