An oblique photography device for drones

Abstract

The invention provides an oblique photography device for unmanned aerial vehicles. The device comprises a vertical lens holder(1), four oblique lens holders(2), a vertical lens and four oblique lenses; the vertical lens holder (1) is a hollow cylindrical structure with a circular baffle (6) at one end thereof; the circular baffle (6) and the end of the cylindrical structure together form a cylindrical recess; the vertical lens is mounted on the vertical lens holder(1) and is located at a center position; a rectangular plate (5) is fixed on each of the four sides of the vertical lens holder (1), and a long baffle (4) and a short baffle (3) are vertically mounted on the rectangular plate (5) and a rectangular groove is opened therebetween; the four oblique lens holders(2) are respectively installed between the long baffle (4) and the short baffle (3); the four oblique lenses are respectively mounted on the four oblique lens holders(2).

Description

technical field [0001] The invention relates to the technical field of photography for drones, in particular to an oblique photography device for drones. Background technique [0002] Drones are unmanned aircraft. UAVs have a wide range of uses, no risk of casualties, strong survivability, good maneuverability, and easy use. They play an extremely important role in modern warfare and have broad prospects in the civilian field. In order to meet the needs of practical applications and realize real-time and comprehensive monitoring of images, the UAV aerial photography platform should try to ensure multi-angle and no blind spots to capture image data at every moment, so as to ensure that the ground receiving system can obtain more accurate aerial image data. For observation, decision-making and related follow-up processing. In applications such as detection of high-risk areas, border defense monitoring, and ground target attacks, the accuracy, visibility, and real-time perfor...

AI Technical Summary

Problems solved by technology

[0003] Due to factors such as complex flight characteristics, high flight speed, and variable imaging conditions of UAVs, sometimes the acquired remote sensing images will have low contrast, blur or even occlusion.

As a result, the image quality is reduced, the shooting angle is not complete, and a complete image cannot be obtained, which not only prevents the ground personnel from clearly observing the ground situation, but also is not conducive to the subsequent processing and analysis of the image, such as target tracking and positioning, etc.

In addition, the lens and the bracket used to install the lens are easily damaged and easily eroded by dust and rain, resulting in a reduction in service life
