Whisk broom type multi-view aviation oblique photography camera and imaging method thereof

Abstract

The invention discloses a whisk broom type multi-view aviation oblique photography camera and an imaging method thereof. The device structurally comprises a base mounted on an aircraft, a pitching ring frame connected to the base through a pitching shaft, a transverse rolling ring frame connected to the pitching ring frame through a transverse rolling shaft, a pitching shaft servo motor for driving the pitching shaft, a transverse rolling shaft servo motor for driving the transverse rolling shaft, and a vertical photographing unit and an inclined photographing unit which are fixed to the transverse rolling ring frame. The aviation oblique photography camera is large in shooting area and high in shooting efficiency, oblique photography in at most nine directions can be achieved, the technical problem of large-field-of-view high-resolution three-dimensional surveying and mapping under the large-speed-to-height-ratio flight condition is solved, and the aviation oblique photography camerahas the capacity of resisting aircraft attitude disturbance.

Description

technical field [0001] The invention relates to an aerial oblique photographic camera, in particular to an aerial oblique photographic camera and an imaging method capable of realizing large-field-of-view and high-resolution three-dimensional surveying and mapping under the condition of high speed-to-height ratio flight. Background technique [0002] Oblique photography technology is a high-tech developed in the field of international surveying and mapping in recent years. It overturns the limitation that orthographic images can only be taken from vertical angles in the past. Collecting images, it can not only truly reflect the situation of ground objects, obtain object texture information with high precision, but also generate a real 3D city model through advanced positioning, fusion, modeling and other technologies. [0003] Currently used aerial oblique photography devices generally use multiple built-in cameras, which can be placed at different angles to achieve multiple...

AI Technical Summary

Problems solved by technology

[0007] 1. The rotation period of the camera is long, and it is impossible to perform large-field imaging under high-speed-height-ratio flight conditions;

[0008] 2. Image motion compensation cannot be realized, and the shooting quality will be seriously degraded under the conditions of high speed and height ratio flight or long exposure time;

[0009] 3. In order to obtain high-definition images, an external stable platform is required, which severely limits the external envelope of the equipment and increases the overall volume and weight
