Unmanned aircraft AVI-1
_A motor glider type uav, carbon composite structure, wings with flaps. Electric engine, folded propeller.
Integrated with autopilot. Autopilot performs a predetermined route. A decomposed plane is transported in dedicated case (included in kit).
Manual remote control is used in phases of takeoff and landing. 8 channel Futaba FASST 2.4 GHz is used as standard.
The start of AVI is supported by the ramp (folded for the transport) and bungee.
_Digital cameras are selected specifically for
properties of the matrix, the lens and the system
recording images. Currently two types of cameras with fixed focus are used:
DSLR Canon 550D - Allows you to shoot high ground resolution (up to 4-5 cm) in RGB.
Pair of Sigma DP2 compact cameras -enables users to receive a ground resolution of ca. 10 cm. One of them is modified to register the NIR channel (720-1100 nm), and second without modification takes photos in RGB.
Cameras are controlled by an autopilot via the electronic controller, through the dedicated connection cable. Typically images are taken with the forward/side lap of 65-80%.
Set of photogrammetric software
_ We use the professional software kit EnsoMOSAIC developed by MosaicMill (Finland). This software set is used for aerial image processing and DSM production. This is dedicated photogrammetric software developed for aerial images taken with non-metric customer cameras from UAV platforms.
Video transmission system: helps to control the work of cameras. It transmits the camera panel image to the ground video screen/window.
The resulting material has a high resolution (5-10 cm horizontally, vertically,
15 - 30 cm) and high accuracy (2-5 pixels). Autopilot supervises the shooting. Uniform coverage of the longitudinal and transverse images is maintained within 65-80%.
It is possible to mount other sensors such as infrared cameras.
Aerial photographs are widely used material in the inventory of objects in the field. They can be used in almost every area of the economy - from agriculture through archeology, engineering, through to crisis management. Aerial photos and cartometric products (e.g. orthophotomap, digital surface model) allows you to quickly process information about the area through computer analysis of data.
We are also adapting these products for monitoring of fire.
_Fully cartometric, georeferenced orthomosaics and DSM are comparable to typical orthophotomap. It allows you to identify the location of objects in geographic coordinates, measure the length/area, conducting analysis, visualization of orthomosaic content.
DSM can be used to carry out measurements, observations, analyzes in three dimensional space.
