1 8 th ITS European Congress MiniFaros Low-Cost Miniature Laserscanner Florian Ahlers SICK AG

2 Low-cost Miniature Laserscanner for Environment Perception Focused Research Project: ICT , # Duration: 36 Months (Jan Dec 2012) Coordinator: Kay Fuerstenberg (SICK AG) Budget: 4.8 M (3.2 M EC funding) Consortium: IV 2011 Event, Baden-Baden Location 2

3 Vision & mission Vision: Accident free traffic realised by means of effective environment perception systems Generic, affordable, durable, compact sensor with reliable data Speed up market penetration by facilitating ADAS integration to all vehicle segments 3

4 Accident review results Accidents distributed by car segments 4

5 Objectives Develop and demonstrate a prototype of low cost miniature automotive Laserscanner for environment perception Low production cost Large FoV (250 ) Small size Micro-Electro-Mechanical scanning (MEMs) Omni directional lens to obtain large field of view Integration of TDC and receiver to reduce size and costs Integration of optical and mechanical components Implementation of enhanced object detection and tracking algorithms Serve various in-vehicle applications 5
