Speed limit determination is a complex task that may be solved by fusing data from GIS (Geographical Information System) and camera sensor. Among the existing data fusion models the Dempster-Shafer Belief Theory is found to be the most appropriate in this application. A confidence measure weights each source output, namely speed limit present on road sign and driving situation. Using the discounting...
This paper presents a night time vehicle detection system performing automatic headlamp control in the frame work of driving assistance. In such application dealing with sensor, processing and actuator, we focus on image processing techniques developed in this project. From our embedded camera, image processing enables to detect vehicles ahead and estimates their positions in order to increase driver...
In this paper, we present an improved European speed-limit sign recognition system based on an original ldquoglobal number segmentationrdquo (inside detected circles) before digit segmentation and recognition. The global speed-limit sign detection and correct recognition rate, currently evaluated on videos recorded on a mix of French and German roads, is around 94%, with a misclassification rate below...
The principal interest of currently available bending light systems using vehicle information (vehicle speed, steering wheel angle) is to adjust the beam orientation according to the driver's manoeuvres. However, this kind of lighting is not anticipative and does not take the global driving situations and contexts (bend, city, motorway ...) into account. The use of navigation systems can provide good...
