Multi-target capability facilitates operation in poor weather:
The sensor's reliable performance in poor weather is crucial if driver assistance systems are to be supported effectively. Rain, fog, snow and spray can affect the sensor's ability to measure accurately and thus substantially reduce the entire system's effectiveness.
Ibeo laser scanners are aligned to ensure highly precise and dependable operation even in poor weather. The problems posed by weather conditions have been perfectly resolved with pioneering four-echo technology.
An object, such as a raindrop or another vehicle, would normally generate one reflection or echo per laser pulse. By increasing the number of echoes to as many as four per pulse, Ibeo has significantly optimised and refined object detection. Since the beam generated by each laser pulse is split into four layers, Ibeo sensors can evaluate the data from up to 16 reflections per measurement.
This technology gives rise to absolutely reliable object detection, which entails not only the exact evaluation of relevant object data, but also the elimination of irrelevant data, typically arising from a dirty cover, fog, snow or heavy rain. These artefacts are removed by filtering and/or reported to the driver, so that flawless operation is ensured. This multi-target capability also allows the Ibeo laser scanners to be installed behind plastics and similar materials.
