UK: Aerial mapping company has completed a research project backed by the UK government’s innovation agency, Innovate UK, to develop the use of mobile phones for capturing accurate 3D spatial information.
The nine-month investigation focussed on the use of standard smartphone technology to capture and calibrate video footage and then convert to 3D information. Accurate measurements of essential infrastructures, such as overhead power lines and other utility facilities, could then be extracted using specially developed algorithms and workflows. Designed to provide an accurate record of the feature’s location and its environment, the Bluesky project is expected to appeal to electricity Distribution Network Operators (DNO) and other organizations with a dispersed asset base, as a low-cost measurement and auditing tool.
During the project, Bluesky tested a number of hardware, software and deployment options. These included the use of aerial photography to add control points to the video footage. As the project progressed, it was established that in remote areas there were insufficient features, for example, road markings, lamp posts or buildings, to establish the required control. Bluesky, therefore, developed alternative innovative methodologies including the use of a calibration object or the measurement of a feature within the imagery.
Working alongside project partner ADAS, Bluesky also undertook rigorous testing of the solution establishing and documenting the field data capture process, identifying minimum hardware requirements, such as camera pixel capacity, and additional developments to the data delivery mechanism. Following minor enhancements and additional trials Bluesky hopes to launch the mobile phone mapping tool, complete with data processing and hosting services, in Q2 2018.
Innovate UK praised Bluesky awarding the project a score of 4 out of 5. “Congratulations to the project team for scoring an impressive 4 out 5 – apparently, no one scores 5 out of 5!” commented Rachel Tidmarsh, Managing Director of Bluesky. “Now we have the task of translating the proof of concept design into a market-ready solution, something we have considerable experience in.
“We know from previous work with ADAS, electricity companies and other utility service operators that by providing a more cost-effective data capture, analysis, auditing, and dissemination solution we will significantly decrease maintenance costs releasing essential funds for network upgrades and service improvements. We will also explore other applications of the solution in sectors such as forensics, insurance, and emergency response.”
