Single-lens oblique photography device for aircraft

Abstract

The invention provides a single-lens oblique photography device for an aircraft. The single-lens oblique photography device comprises a lens mechanism, a supporting mechanism and a camera; the lens mechanism comprises a plurality of reflecting mirrors, a switching device and a first power component, and the plurality of reflecting mirrors are fixedly installed on the switching device at different spatial angles; the supporting mechanism comprises a connecting piece and a second power component, and the output shaft of the second power component is fixedly connected with the connecting piece; the camera is arranged behind the lens mechanism, and the reflecting mirrors are arranged on the optical axis of the camera; and the camera and the lens mechanism are fixedly connected to two ends of the connecting piece, and the supporting mechanism is connected to the aircraft. According to the single-lens oblique photography device, the first power component drives the switching device to move to drive the reflecting mirrors at different spatial angles to move to the front end of the camera; the second power component drives the connecting piece to swing to drive the lens mechanism and the camera to swing so as to the change the shooting direction of the camera, and the device is simple in structure, light in weight and small in vibration when the shooting direction is changed, and thus the device is more suitable for aviation shooting.

Description

technical field [0001] The invention relates to a single-lens oblique photography device for aircraft. Background technique [0002] Aerial oblique photography is a high-tech aerial photography technology developed in the field of international surveying and mapping in recent years. It collects space images of different sides of ground objects by carrying multiple sensors with different camera angles on the same flight platform. Oblique aerial photography is different from traditional vertical aerial photography. Aerial oblique photography needs to obtain image data in five directions: down, front, back, left and right. The use of aerial oblique photography technology has the characteristics of high efficiency and good reflection of real ground objects. [0003] A kind of oblique photography device that is widely used at present consists of 5 lenses in total, wherein 1 camera lens is vertically downward, and the other 4 camera lenses are respectively tilted forward, backwar...

AI Technical Summary

Problems solved by technology

[0007] 1. Adjust the tilt angle of the camera through two rotary joints to adjust the shooting direction of the camera. This method reduces the number of cameras, but the angle of camera tilt shooting has certain limitations, and the angle control operation is complicated. When the rotary joint controls the camera to rotate There will be certain vibrations, which will affect the shooting effect of the camera and cause certain difficulties for post-modeling and image processing

[0008] 2. The multi-angle tilting photography device equipped with the gimbal, because the gimbal control panel controls the rotation of the gimbal to take pictures, and after completing three angles, the aircraft needs to be manually rotated on the ground. Its operation is complicated and difficult to control, and it is difficult to be promoted and widely used application

[0009] 3. The camera rotation period is long, and the shooting efficiency and quality will decrease under a certain overlap rate requirement
