Real-time Tunneling Measurement based on an Infrared Optical Tracker
This project develops a stereo camera system to perform tunneling measurement in real time based on optical infrared tracking.
To achieve the goals to track and determine the 3D-coordinates of several static as well as moving optical targets in a large measurement volume under tough conditions light vibrations, dust and interfering light, an infrared optical tracking system, usually used for standard room-sized indoor virtual reality applications, is heavily extended and optimized.
For measurements in a tunnel it is a sub task of the tunneling measurement system to assure the correct geometrical control of all tunneling activities. Due to the rapidly increasing automation of the tunnel construction in the last years, tasks in the field of positioning and controlling of construction vehicles and robots must be fulfilled as well. These tasks require novel measurement systems to determine the position of targets in real time. Furthermore these systems should be capable in the future to capture multiple objects (machines, robots, construction workers) at the same time as well as moving objects.
With RTMIOT the first fundamental requirements will be fulfilled to achieve the future goal of automated positioning and control of construction vehicles.
