SICK-TiM laser scanner in UAV inspections of overhead power lines, the competition entry of students from Aalto University, has won the innovation competition organised by SICK Oy. 

The team consisting of technology students developed a new way of using a small laser scanner in a robot helicopter and applying it to overhead power line inspections. Continuous monitoring of power lines prevents accident risks and improves the reliability of the electricity distribution network.

In the innovation, the observations made by the laser scanner were used simultaneously in specifying the flying route, avoiding obstacles and providing a rough point cloud. The concept provides a modern alternative to traditional power line inspections such as visual inspections by air. The innovation will also reform the power line inspection methods that use remote controlled aircraft.

‘The robot helicopters currently used for inspecting power lines are big and expensive – and for safety reasons they fly high above the trees and supporting pillars. We decided to turn the situation on its head. A small and inexpensive robot helicopter equipped with a laser scanner can inspect power lines as close to them as possible and provide the measurement material a lot more cheaply than earlier methods,’ says Atte Korhonen, the leader of the student team.

‘This is a big thing for the . Professor Henrik Haggrén, Senior University Lecturer Petri Rönnholm and I can only say that it is wonderful to work with such extremely talented students. They only need a little push and an opportunity, and they will go and innovate miracles,’ says Hannu Hyyppä, Professor of Measuring and Modeling for the Built Environment.
