Drone Inspection South Australia Thermal Imaging – HV Power Assets Utilities

Drone hire Adelaide offer Drone inspection services for Utility companies in South Australia and Australia wide. Historically, powerline inspection has been manual.

Forward-thinking Electrical companies, drone technology and capabilities are advancing rapidly in many ways.

The possibilities for data capture by drones have expanded considerably. upgraded to a variety of cameras in including the DJI H20T and sensors systems capable of capturing a wealth of data. In addition to standard cameras, you have the technology, such as  Flir thermal imagery to identify hotspots; LiDAR (light distancing and ranging), which can build a 3D map of the physical world of electrical poles and networks; This Lidar can use different wavelengths of light to identify plant species and vegetation risks. 

Drone Hire Adelaide have many different options for our clients. The way we analyse and capture the data using Asset Inspection software can save our clients a lot of time and money. Drone Hire Adelaide can use AI to monitor your assets using Scopito data software. 

 

LiDAR
Or Light Detection And Ranging uses light to determine the distance of an object from the LiDAR-sensor. The sensor (here: attached to a flying object) sends down pulses of laser, which reflect off the surface of objects below it. The LiDAR-sensor also contains a GPS-receiver, which constantly measures x- and y-coordinates alongside the sensors’ height above the ground.

The final component of the sensor is the Inertial Measurement Unit. The IMU tracks the position of the sensor relative to the ground, to account for the movements of the object, the sensor is attached to.

Data from these three components is computed, to give a very accurate and detailed 3D point-cloud of the landscape below the LiDAR-sensor. The point-cloud needs to be further processed, to achieve a true view of the landscape/object.

 

Photogrammetry
This paper will focus on aerial photogrammetry, where images are captured from a flying object.

Photogrammetry uses the x, y, z coordinates of two or more overlapping images, to create a 3D-model of an object or an area. Images from almost any camera can be used in this process, as long as they meet resolution requirements. Photogrammetry 3D-models are accurate enough, to be used as basis for aerial measurements of heights above ground level, and distance between two or more points.

A camera and post-processing software is needed to create the 3D-model.
