Unmanned aerial vehicles New possibilities using UAV in remote sensing

of the environment Jakub KARAS

RPAS - remotely piloted aircraft system

UAS - unmanned aerial system

UAV - unmanned aerial vehicle ...is an aircraft without a human pilot aboard. Its flight is controlled either autonomously by onboard computers or by the remote control of a pilot on the ground or in another vehicle

ADVANTAGES: • significantly cheaper to operate (compared to

usage piloted machines)

• easy handling and mobility

• high flexibility for the use of machines in action

• possible to use (takeoffs and landings) even in hard-to-reach areas

• low noise operation

• resistance - extremely dangerous locations

• high resolution images and videos

• other potential benefits of the acquisition specific data in connection with the physical microsensors

How to choose right UAS Each Unmanned Aerial System has its own specifics with which we calculate and adjust the selection of

the purpose for which it is acquired ...

RPAS/UAS – specifications

Copter x wing types

Copter

- variability of different sensors, limited weight - the use of mapping, through monitoring, after shooting - vertical take-off and landing (some even from hand) - online video transmission from the sensor - manual x automatic flight

Wing (Plane)

- limited to mapping a predetermined sensor - take-off from the hand or from the ramp - landing automatic (manual)

WING UAV take-off from the hand or from the ramp

SENSORS • RGB camera • Multispectral camera • Hyperspectral camera • Thermal camera • Laser scanner • Specific sensors (gas sensors etc.)

IDENTIFICATIONS DRAINAGE SYSTEMS

The possibility of using remote sensing to identify drainage systems

• direct identification of lines of drains, fragments until comprehensive drainage systems (DS) using different means and acquisition of various types of data

• accurate topologies and determine their actual position

• in the field (correction of the project documentation)

• Using different outputs and sensors from UAV during different weather conditions

VOLUME MEASURING / MAPPING OF THE CURRENT SITUATION

VOLUME MEASURING

Calculations volumes of landfill materials and their monitoring changes over time - in sandpits, quarries and mines, if we knowing the digital terrain model of the original plane.

After several testing at landfills coal mines Tušimice the measurement accuracy of the resulting volumes of 0.2% over the conventional method of stereo/ photogrammetry.
