Unmanned aerial vehicle for surveying and mapping aerial photography

Abstract

The invention discloses an unmanned aerial vehicle for surveying and mapping aerial photography, which comprises a rack ring, propeller arms and propeller assemblies, a plurality of spokes radiating from the circle center to the edge are distributed in the rack ring, six piston sleeves are evenly distributed on the circumference of the rack ring, the axes of the piston sleeves point to the circle center of the rack ring, and the axes of the piston sleeves point to the circle center of the rack ring. A propeller arm coaxially matched with the piston sleeve in a sliding mode is arranged in the piston sleeve in a penetrating mode, and a propeller assembly is arranged at the end, away from the circle center, of the propeller arm; an undercarriage is fixed to the lower portion of the rack ring through spokes, a battery flight control device is arranged in the undercarriage, and a camera holder device is arranged in the center of the lower portion of the undercarriage. Compared with the prior art, when the unmanned aerial vehicle is close to the ground, the occupied ground space is small so as to adapt to different terrains and geographic positions; the blades are ensured to obtain higher rotating speed and maneuverability, so that the unmanned aerial vehicle is more accurate to operate and control, has better stability and wind resistance at high altitude, and ensures that a shot picture is stable.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle for surveying, mapping and aerial photography. Background technique [0002] UAV aerial survey is a powerful supplement to traditional aerial photogrammetry. It has the characteristics of flexible maneuverability, high efficiency and speed, precision and accuracy, low operating cost, wide application range, and short production cycle. It has obvious advantages in acquisition. The digital camera, digital color aerial camera and other equipment carried by the system can quickly acquire surface information, ultra-high-resolution digital images and high-precision positioning data, which is convenient for the development and application of application systems in various environments. application. UAV aerial photography can be widely used in major national project construction, disaster emergency response and treatment, land supervision, res...
