3D Asset Inspection – Creating a digital twin

Built infrastructure management (BIM) systems are experiencing a change in the way asset inventories are monitored and maintained. The creation of a digital twin of real-world assets is more commonly referred to as 3D reality capture and is now business as usual for much of the asset management industry. The University of Melbourne and the Victorian Government are partnering to deliver Australia’s largest urban renewal project at Fisherman’s Bend incorporating this technology. Whilst having a high-resolution 3D digital twin of an asset is a fun and engaging means of visualisation, conversations on the topic are now shifting to how to …

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

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 …

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, …

Uaviation launches its new asset inspection UAV

Uaviation’s robotics engineers designed and constructed a new unique remotely piloted aircraft. Equipped with a revolutionary new positioning system that uses ten sonars and ten 3D cameras to “sense and avoid” obstacles. It has been built to inspect hard-to-reach locations like bridges, overpasses and coal conveyors. It can hover in place just centimeters from an obstacle (all withour GPS) while it carefully surveys and inspects This UAV sports an upward-facing camera and gimbal and live HD broadcast to the ground so engineers can pick and choose what they are looking at.

UAVIATION COMPLETES TESTING OF ITS NEW THERMAL IMAGING UAV

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.
