Abstract

An unmanned airship low-altitude photography measuring device comprises an unmanned airship, a flight controller, a tri-axial stable cradle head and a digital camera. The unmanned airship is formed by a primary air bag, an auxiliary air bag, a tail rudder and an engine nacelle; and the auxiliary air bag fixed inside the primary air bag is arranged according to an adjustable volume with certain proportion. According to actual conditions of a measuring area, firstly a user performs airlines planning, calculates flight lines, airline intervals, and flight photograph intervals and flight height in advance, and transmits calculated data to the flight controller to be stored. The unmanned airship is controlled by the flight controller after launching through remote control, and the flight controller controls the tail rudder and the engine nacelle to fly according to preset airlines and speed. In flying process, the flight controller controls the digital camera fixed onto the tri-axial stable cradle head to photograph over ground according to specified distance and/or intervals. Compared with a traditional photograph measuring device, the unmanned airship low-altitude photography measuring device has the advantages of high maneuverability, low cost and high safety, and is adaptable to surveying and mapping works of large-scale topographic map of medium and small areas.

Description

A kind of unmanned airship low-altitude photogrammetric apparatus

Technical field:

The utility model belongs to the Surveying Science and Technology field, specifically is a kind of low latitude photogrammetric apparatus based on unmanned airship.

Background technology:

Along with mapping science and technology and development and national economy, resource and ecology environment investigation, detection and assessment, E-Government, digital city and Important Project construction all need strong, the high-precision topographic map data of feasibility.How to obtain, upgrade basic data rapidly and accurately is the long-term problem of paying close attention to of national basis construction department always.If can realize that the low latitude below 500 meters is photogrammetric, then can be completely free of the influence that cloud layer blocks, the mapping of 1: 2000～1: 500 large scale topographical map in zonule in satisfying.

Summary of the invention:

The utility model provides a kind of unmanned airship low-altitude photogrammetric apparatus, help overcoming traditional photography and measure the shortcoming that cost height, air traffic control strictness, alerting ability are not enough, can not measure among a small circle, the large scale topographical map of zonule mapping in can satisfying.

The utility model is achieved through the following technical solutions:

A kind of unmanned airship low-altitude photogrammetric apparatus, comprise the unmanned airship of forming by main gasbag, balloonet, tail vane, engine pod, also have flight controller, three axis stabilization The Cloud Terrace and digital camera, it is characterized in that: the volume setting by a certain percentage of the balloonet of main gasbag internal fixation also can be adjusted, according to the measured zone actual conditions, at first carry out flight course planning, preliminary evaluation flight path, track spacing, take pictures at interval and flying height, and the data of calculating are reached flight controller store; By flight controller control, flight controller control tail vane and driving engine are by predefined course line and speed flight after remote control is taken off for unmanned airship; In flight course, the digital camera that flight controller control is fixed on the three axis stabilization The Cloud Terrace is taken pictures over the ground by distance to a declared goal and/or time gap; Take photo by plane and photo is exported to computing machine after finishing and handle.

The beneficial effects of the utility model: need not special-purpose landing runway, not retrained by air traffic control, alerting ability is strong, is specially adapted to the topographical survey in complicated topographical conditions zone.The utility model has manoevreability height, the low and safe characteristics of cost than the traditional photography measurement.The large scale topographical map mapping operations of zonule in being suitable for.

Description of drawings:

Fig. 1 is a structural principle scheme drawing of the present utility model.

Each label among the figure: 1-main gasbag, 2-balloonet, 3-tail vane, 4-engine pod, 5-three axis stabilization The Cloud Terrace, 6-digital camera, 7-flight controller.

The specific embodiment:

The utility model comprises the unmanned airship of being made up of main gasbag 1, balloonet 2, tail vane 3, engine pod 4, and flight controller 7, and three axis stabilization The Cloud Terrace 5 and digital camera 6 are formed.

According to the measured zone actual conditions, at first carry out flight course planning, preliminary evaluation flight path, track spacing, take pictures at interval, flying height, and computed information reached flight controller store; Unmanned airship is promptly controlled by flight controller after remote control is taken off.According to the difference of flying height,, adjust the ratio of main gasbag and balloonet, to adapt to different flying height requirements by this area method of operation commonly used; By volume, main gasbag fills 90%～100% helium or hydrogen, and balloonet fills 10%～0% air.According to predefined course line, control tail vane 3 and driving engine are by contemplated route and speed flight; In flight course, keep attitude by three axis stabilization The Cloud Terrace 5 control digital cameras 6, and take pictures over the ground by distance to a declared goal or time gap by flight controller control camera.Take photo by plane and photo is exported to computing machine after finishing and handle.
