Project description

Mobile robots have the potential to bring disruptive changes to our everyday lives. To achieve this, such systems need versatile sensing capabilities to understand the world around them and to move around safely.
Sevensense Robotics develops camera systems that allow robots to observe and understand their surroundings and to estimate their own position precisely. These measurements need to be highly accurate, otherwise the robotic system cannot operate reliably. Before shipping sensors to machine manufacturers, they need to be factory calibrated such that optimal performance can be guaranteed.
Within this project we focus on accurate, reliable and efficient calibration methods for such sensing systems, which allow for a swift and economic calibration process, that still guarantees the high requirements for industrial applications.

What is special about the project?

This project is expected to have tangible results for the calibration of visual localization systems. The newly developed calibration procedure will enable reliable and accurate factory calibration of multi-camera systems and with that boost the go-to market efforts of Sevensense Robotics AG. Calibration is one of the most crucial steps for such a complex sensing system to work properly and live up to customers’ expectations and needs.


The project has been completed successfully. During the project a novel calibration method for multi-sensor systems was developed, implemented and rigourously tested. It provides reliable and highly accurate information about sensor systems that are fundamental for ground robots and their perception. The new procedure is also highly user friendly and operable by non-tech experts, which is essential for the mass production of robotic systems, where factory calibration has the done efficent and should only be a small work effort at the end of a factory assembly line.
The spin-off company Sevensense Robotics is currently using the developed methods in several customer projects and is in the process of fully commercializing the solution. It plays an essential role for the successful deployment of the products of the company into customer machinery. The continuation of the project is financed with sales and engineering revenue and investor capital.
