Pittsburgh, PA – May 5, 2017 – Kaarta, innovator of the next big leap in 3D modeling, took first place for the second consecutive year at the Microsoft Indoor Localization Competition held at the IPSN 2017 conference. Not only did Kaarta achieve the best accuracy score overall, it did so in real time without the use of prior maps or any infrastructure such as beacons or ultrawideband radio and required no post processing.

The Microsoft Indoor Localization Competition is a well-known annual benchmark for assessing many approaches to indoor localization. This year, technologies from both academia and industry were put to the test in a space encompassing 600 square meters and two floors. Each team was required to report the coordinates of 20 test points that were previously measured by Joint Research Centre (JRC) – the European Commission’s science and knowledge service – using a tripod-mounted laser scanner for the purpose of ground truth assessment. With a remarkable 0.03-meter average localization error as compared to ground truth, Kaarta bested its own winning accuracy mark from last year and demonstrated the extreme speed and ease of use of its technology.

“It’s been exciting to take part in this competition and we’re thrilled to have won a second time in as many years,” said Kevin Dowling, CEO of Kaarta. “We are proving that real-time results are attainable, and that accuracy needn’t suffer for the sake of speed and usability. 3D modeling through mapping and localization is ripe for a step change especially for indoor applications, underscored by our maxim that ‘the inside is as big as the outside.’ ”

Kaarta completed the challenge hand carrying Stencil™, Kaarta’s mobile, lightweight, and low-cost system that unleashes the integrated power of mapping and real-time position estimation.  Like all Kaarta devices, Stencil is powered by Kaarta Engine which uses multiple sensors including lidar, IMU, and camera to feed Kaarta’s core set of algorithms to build a faithful map of surroundings and determine position within it, all in real time without prior maps, infrastructure or GPS, and with no post processing.

Kaarta will next demonstrate its 3D modeling technologies at GeoBusiness in London, May 23rd-24th, 2017.
