Unmanned aerial vehicle for historic building oblique photography

Abstract

The invention discloses an unmanned aerial vehicle for oblique photography of ancient buildings. The unmanned aerial vehicle comprises an unmanned aerial vehicle body, a movable mounting frame is mounted at the bottom of the unmanned aerial vehicle body through bolts, the movable mounting frame comprises an arc-shaped plate and two groups of protective plates mounted at the tail end of the arc-shaped plate, and a rotating rod is horizontally arranged at the tail end of the cambered plate; one end of the rotating rod is movably arranged on the inner wall of the arc-shaped plate, and the other end is provided with a motor I; and the power output end of the motor I is connected with the rotating rod, an installation plate is fixed to the bottom of the motor I, the installation plate is fixed to the bottom of the unmanned aerial vehicle, the motor I is connected with a controller, the controller is connected with an acceleration sensor, the acceleration sensor is installed on one side ofthe movable installation frame, and a movable adjuster is installed on the cambered plate. The protection mechanism specially used for the unmanned aerial vehicle to install the photographic equipment is designed, the photographic equipment can be automatically tightened and protected under the condition that the photographic equipment falls off due to emergency situations, and the safety of high-altitude photography of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of drone photography, in particular to a drone for oblique photography of ancient buildings. Background technique [0002] In order to inherit and carry forward the city's history and culture, in view of the current situation of missing drawings of ancient buildings, point cloud data can be collected by means of 3D laser scanning and tilted photogrammetry by UAV. Pointcab and ContextCapture can be used to analyze the data and build a 3D vector model, and study the scanner model A method of integration with the UAV model. Based on this, reverse build the BIM model, study the establishment of ancient building component families, compare and analyze with physical ancient buildings, explore methods for reducing errors and accurate modeling, study and analyze ancient buildings more intuitively, and discover new clues and values At the same time, storing BIM models is of great significance for the protection, mai...

AI Technical Summary

Problems solved by technology

[0003] However, the existing unmanned aerial vehicles used for photography of ancient buildings have the following problems in use: (1) usually the bottom of the unmanned aerial vehicle is directly installed with a photographic device for shooting through a mounting frame, but in actual During operation, it is inevitable that the drone will collide with the building during operation, causing the drone to fall. Since the photographic equipment is installed at the bottom and lacks corresponding protective measures, once an emergency occurs, it is easy to directly cause damage to the photographic equipment. Safety (2) The installation method of the existing camera equipment on the UAV is relatively fixed, which cannot meet the multi-angle adjustment in the process of photography, which affects the effect of photography
