3D Image Sensors

Events

The development of circuits for pulsed time-of-flight (TOF) laser range finders has been one of the main areas of research at the Electronics Laboratory of University of Oulu already over 30 years. Head of the laboratory and the group is professor Juha Kostamovaara. There are many applications for pulsed TOF laser radars such as the positioning of tools and vehicles, the profiling and scanning of surfaces, anti-collision radars and traffic perception, for example.

Main activities

Time-Of-Flight (TOF) measuring technique relies on the measurement of the round-trip time needed by a light pulse to travel from the measurement system to a target and back again, which has been actively investigated by the SOI research unit since 2002, exploring a number of different techniques.

Technologies

The first developments in 3D Vision at SOI were done in the framework of the Opto3D project since year 2000, with the development of an intelligent electro-optical sensor for driving scenarios detection and object recognition [1]. Since then, SOI investigated and developed a number of different operating principles for indirect time-of-flight imaging using CMOS technologies, from the simulation and development of the sensing device, to the integrated circuit and 3D camera system.
