Multi-angle unmanned aerial survey system

Abstract

The invention discloses a multi-angle unmanned aerial survey system. The multi-angle unmanned aerial survey system is provided with a six-rotor-wing unmanned aerial vehicle, and each multi-view-angle inclined camera composed of five camera lenses is carried on the six-rotor-wing unmanned aerial vehicle. Each multi-view-angle inclined camera comprises a shooting unit, a controlling unit and a hanging unit. The six-rotor-wing unmanned aerial vehicle comprises an unmanned aerial vehicle flying platform system, a GPS, a flying controlling system, a remote sensing shooting system, a ground controlling system and a signal transmitting system. Ground images can be collected at the same time at multiple angles, in this way, the defect that according to a traditional aerial photography technology, shooting can be performed only at a vertical angle is overcome, the actual conditions of a ground feature can be reflected more really, and the defects in orthophotography are overcome; through integrating POS data, DSM data, vectors and others, a three-dimensional model establishing technology based on image intensive matching is established, a digital city model is rapidly and efficiently established, and therefore the working cost for three-dimensional model establishing is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of aerial photography, and in particular relates to a multi-angle unmanned aerial survey system. Background technique [0002] In January 1998, the United States put forward the concept of "Digital Earth" based on its own interests and global political, economic, and military strategic goals. More than 100 cities in China have carried out the construction of "Digital Cities". As an important part of digital city construction, 3D modeling of digital cities has also developed rapidly. At present, most of the areas where digital cities are built have carried out a lot of 3D modeling work, but 3D modeling work is costly, slow, and consumes a lot of manpower. and physical resources. In recent years, the field of international geographic information has combined traditional aerial photography technology and digital ground acquisition technology to develop a high-tech called airborne multi-angle oblique photograph...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-angle unmanned aerial survey system, which aims to solve the problem of establishing a 3D model by taking pictures on the spot in the prior art. It can be photographed from a vertical angle, but it cannot truly reflect the actual situation of the ground features, and the problem of insufficient orthophotos
