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 …

Drones in Construction and Earthworks

Australian construction, road and rail works. Drones and their application is a popular topic many Australian business.  The construction industry were early adopters of drones. The industry has been using them and other unmanned vehicles to provide a range of services since 2013. The application and use of drone technology in the construction industry falls into three main categories; survey, progress monitoring, and asset inspection. Each of these applications require specialist knowledge and technology.  The following will focus on the drone survey applications. The movement of large volumes of the earth is an essential part of construction. The logistics, engineering effort …

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 …

A Guide to Thermal Mapping and Surveys.

Uaviation provides thermal mapping, inspection and survey solutions using UAV drone systems. Through simple oblique photography, complete GIS data sets or more complex 3D modelling, the use of this technology is helping our clients monitor a range of asset maintenance and environmental issues.  We use airborne GPS and IMU to optimized image collection methods for image geopositioning, providing our customers with geospatially-accurate maps for precise measurements and locations. The visualization of thermal maps varies between application. Typically, the simplest 2D map form of visualisation is used for analysis purposes, however, thermal maps can be in 2D, 3D, 4D and even …

Weed detection, classification and mapping using drones.

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 …

DroneDeploy “Mission Exceeds Maximum Radius” SOLVED

I’ve been using DroneDeploy as a flight control system frequently in the last couple of weeks. Whilst good, I keep encountering issues during pre-flight. On this occasion I encountered “Mission Exceeds Maximum Radius” during the pre-flight checks for our Inspire. I didn’t know this at the time but within the DJI GO app there is a section called ‘distance limit’ under the MC Settings that acts as a geofence. If your mapping mission exceeds this limit, it will throw you a settings error. Just uncheck distance limit or change it to something larger than the maximum distance for your mission. …

DroneDeploy Waiting for Drone SOLVED

  Last week was our first attempt at using the DroneDeploy app as a flight control system for our DJI Inspire. Whilst the operational delivery of the app was simple, in the initial setup can we encountered a number of problems. These problem are all drawn from safety precautions taken by the app which is a good sign, however error messages are not very descriptive. The first problem we had was the “Waiting for Drone” message. On connection of the inspire I was not able to connect the drone as this message would remain. I was conducting these test connections inside …

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, …
