Solution to Geographical Mapping

15MINI

World's Fastest

SCHEME INTRODUCTION

In recent years, geographical mapping information industry has been developing rapidly, it not only played remarkable role in national informatization and modernization, but also made important contribution to economic growth promotion and social stability. Peoples’ living standard has been increasing, the whole community’s demand for geographical mapping information industry has been dramatically increasing, so geographical mapping information industry is required to be developed urgently, to enrich geographical information products.

TRADITIONAL MAPPING

Cadastral survey conducts accurate measurement for the coordinate of land parcel ownership boundary, and accurately draws elements including location, area, ownership and use of the land parcel and its attachment on the drawing, as well as makes record of mapping in special forms. Generally, traditional cadastral survey adopts manual work, and uses total-station and RTK for outdoor survey. However, RTK is easily affected by satellite signal, which is not easy to be fixed in the place of built-up area and trees; while total-station is required to move for orientation, so work efficiency is quite low. This work method requires high cost, long time work and low efficiency. However, traditional 1:500 air survey is not able to meet requirements of cadastral survey accuracy.

UAV SYSTEM PROFILE

Smart eagle-15mini is a four-rotary foldable petrol-electric hybrid UAV, which adopts international general use 92# petrol as the power to take 2kg load for 2-hour continuous flight.
Solution to high cost, long time, low efficiency of cadastral survey

SMART EAGLE-RELIABILITY

Automatic Restart In The Air

Smart eagle-15 mini is equipped with automatic restart function in the air. When the UAV detects the stalling of the engine, automatic restart in the air will be activated, which the process is not required to be operated manually, so it furtherly increases flight reliability

Automatically make a return voyage alerted by primary low voltage

When the UAV detects the voltage is too low, it will automatically make a return voyage to its original position.

In-situ landing alerted by secondary low voltage

When the UAV’s voltage reaches to secondary low voltage alert, the UAV will land slowly by its capacity of lithium battery, to avoid damage due to its free fall to the ground

KEVLAR Materials

It is once-forming through 24-hour press under 2T pressure and 100° temperature, so it has the features of lightweight, high strength and high toughness. It can guarantee no fracture or oil leak after free fall with the whole UAV.

SMART EAGLE-LOAD

30X ZOOM

30x optical zoom and 6x digital zoom,i.e. maximum 180x can be achieved,to observe every details of the scene in the air.

5-LENS CAMERA

1:500 high precision photograph can be taken, and then be created into model. Data including distance, area and volume can be measured from the model, and current disaster situation can be visualized as well, so the rescue and evacuation plans are able to be made accordingly.

LASER RADA SENSOR

Through laser radar sensor, UAV is able to emit laser pulses and measure distance and altitude accurately by return signals, so as to create 3D composition.
