Triaxial orthographic nacelle of unmanned aerial vehicle

Abstract

The invention discloses a triaxial orthographic nacelle of an unmanned aerial vehicle, which is composed of a pitching component, a roll component, a heading component, and a circuit board component, wherein information transmission between the pitching component, the roll component, the heading component, and the circuit board component is realized through connecting cables. According to the nacelle, a full frame single lens reflex and a visible light vidicon can be carried; a stable platform is provided for aerial photogrammetry of geological disasters; the nacelle is guaranteed not to be affect by influences of rocking and vibration of an airplane during the flying; a sensor optical axis can be perpendicular to the ground horizontal plane; the nacelle can be applied to the unmanned aerial vehicle aerial photogrammetry, and has the characteristics of compact structure, small size, light weight, and strong environmental adaptation and load fitness; an external electromechanical interface is simple; the operation and the maintenance is simple and convenient; well application and popularization value is adopted.

Description

technical field [0001] The invention relates to a three-axis orthographic pod for an unmanned aerial vehicle, which belongs to the technical field of photoelectric equipment in aircraft and aviation technology. Background technique [0002] In the process of remote sensing aerial photography, remote sensing instruments are required to be as stable as possible, especially aerial photogrammetry, which requires that the heading overlap rate and side overlap rate are both greater than a certain value, which requires the camera to keep approximately vertical to the ground. [0003] When the attitude angle changes greatly, the aerial photography images tend to have too low or no overlap, resulting in aerial photography loopholes, resulting in the unusable route image data with loopholes, and the aerial photography needs to be re-used. [0004] Therefore, it is necessary to use a stable platform to compensate the attitude change of the flying platform to ensure the quality of camer...

Problems solved by technology

[0007] At present, although foreign light low-altitude aerial photography gimbals have good orthographic effects, they are expensive and cost several million, which is not conducive to large-scale promotion and use.
