How to generate a Thermal Orthomosaic / Map with radiometric information

The principals of photogrammetry are well documented and need not be explained in detail, however with the continual miniaturisation and improved resolution of thermal cameras begs the question: Can you apply the same principals of photogrammetry to thermal images? The short answer is yes, however the idea becomes more difficult when you attempt to retain the radiometric information. Below is a workflow that will allow you to generate thermal Orthomosaic and retain the radiometric information. Most radiometric sensors like the Tau 2 allow for 640×512 resolution .rjpeg images to be captured. The radiometric data however is not contained within the …

3D modelling rock revetments

31 July, 2019 Posted by Nigel Brown 3d Modelling Aerial Inspection Mapping Revetments Environment Inspection Mapping

Recently the team at Uaviation have been focused on developing and applying new 3d modelling technology to the management of erosion prevention assets. The focus has primarily been on automating and standardising the assessment of coastal rock revetments. Uaviation’s systems focus on collection and analysis of: Voids Within the Revetment; Rock Displacement and Erosion; Exposure of Geo-fabric; Debris Build-up; and, Slope Differentials and S-curve development. Using unmanned aircraft (drones) Uaviation collect, detailed, high resolution imagery of the armour. Voids in the armour surface is measured using aerial imagery analysis where the tessellation and particle size of rocks are analysed. Uaviation …

Weed detection, classification and mapping using drones.

27 September, 2016 Posted by Nigel Brown Aerial Drone Invasive Mapping Vegetation Weed Agriculture Environment Innovation Mapping

Many of the safety risks in the natural resource industry are drawn from having staff traversing difficult ground. This risk is exacerbated when these staff have a task to perform such as filling data sheets, that require them to shift their attention from their surroundings. Interest in aerial means of capturing data to negate this risk and other challenges is increasing. We have developed a number of methods to map weeds with varying degrees of automation in the analysis process. Capturing extremely high resolution data with drones is simple, cheap and easy. The challenge is converting that data into actionable …

Matthew Lee Meets the Minister for Energy, Environment and Climate Change

I had the pleasure of representing Uaviation as a panel member the DELWP RPAS providers at a press release by the environment minister Lily D’Ambrosio at Melbourne Zoo on Saturday. Thinking initially that my role was just to deliver an example drone for the minister to point at, I had not anticipated what turned out to be a more involved role. The extent of the coverage we received from the press and the enjoyment I would draw from this experience. My first job was to set up our drone next to another RPAS provider’s drone. Feeling somewhat intimidated by their 40kg+ monster of an aircraft, …

NDVI Imaging

25 August, 2016 Posted by Nigel Brown Agriculture Environment Innovation Mapping

The benefits of using UAV technology to measure crop health and improve production have excited agriculturalists for years. By seperating light bands such as blue, green, red, and near-infrared and measuring the intensity of light reflected from plants, stress can be identified significantly sooner than with the naked eye. Crop yields can be boosted by using imagery to assist in scouting, identifying nitrogen deficiencies, and detecting faulty application equipment and irrigation systems. Technologies such as digital cameras, UAVs (Drones) and big data computing have matured to a point where regular, high quality imagery is available to all farmers. The affordability of unmanned aircraft means that …

UAVIATION COMPLETES TESTING OF ITS NEW THERMAL IMAGING UAV

3 September, 2015 Posted by Nigel Brown Agriculture Environment Innovation Inspection Technology Testing Thermal Uncategorized

Uaviation has completed testing of its new thermal imaging drone. Sporting the highest quality radiometric thermal camera, and a separate visual camera, the UAV is capable of recording over 2 million seperate temperature readings each second. The platform will be used to extend Uaviation’s asset inspection services to new clients. Services include underground leak detection, friction and wear detection, insulation and photvoltaic cell inspection.
