Embodiment Construction

[0010] The embodiment is described in detail below:

[0011] The drone aerial remote sensing data acquisition system is characterized in that,

[0012] The one-button take-off automatic aerial photography system introduces polymer shock-absorbing balls to make the working condition of the IMU sensor more stable and ensure the stability of the flight. The flight route is automatically arranged according to the aerial survey requirements, and the course and side overlap and the aerial survey data can be flexibly set. Resolution, flight speed of the flight platform, the ground control terminal monitors the flight status in real time by analyzing the data link sent back by the flight control system in real time, supports one-key take-off, and automatically returns after the mission is completed;

[0013] The multi-camera precise exposure control system uses FPGA to process the exposure tasks of each camera in parallel, reads the time in the time reference register, and stores them...

Abstract

The invention belongs to the technical field of a remote sensing technology apparatus and, in particular, relates to an unmanned aerial vehicle (UAV) aviation remote sensing data acquisition system. The invention discloses the UAV aviation remote sensing data acquisition system characterized in that for a one-key take-off automatic aerial photographic system, high molecule polymerization damping balls are introduced to make the condition of an IMU sensor more stable, the FPGA-based multi-channel micro high-speed data storage technology is adopted to distribute high-speed serial data to a five-way parallel processing unit for data storage, a five-way SATA interface is adopted, and a solid state disk is used for data high-speed storage. The system of the invention has the beneficial effects of realizing absolutely independent time reference measurement of various cameras, and coordinately controlling the simultaneous exposure of the multiple cameras by parallel control.

Description

technical field [0001] The invention belongs to the technical field of remote sensing technical appliances, and in particular relates to an aerial remote sensing data acquisition system of an unmanned aerial vehicle. Background technique [0002] With the continuous development of computer software and hardware technology and sensor technology, human beings have more means of surveying and mapping. Oblique photography technology is a surveying and mapping technology that has emerged in recent years to obtain surface data. Using oblique photography technology to obtain highly overlapping image data as material, it can be processed automatically to obtain 3D model data, digital surface models, and real orthophotos. [0003] At present, the data acquisition module in the tilt camera system mainly adopts large and medium-sized measurement digital cameras or ordinary SLR and mirrorless cameras, which generally have the problems of large size and heavy load, and can only be instal...
