The invention relates to a method for calibrating a road monitoring device, in which the road monitoring device records a predetermined monitoring area and detects objects in the monitoring area, and determines and provides object data relating to the objects, in particular the positions thereof. Within a predefined calibration period, the position of the detected object relative to the road monitoring device is recorded and thereby an accumulated object residence map is formed. In addition, there is a world coordinate map of lanes or lane centers of the monitored area and the position of these lanes or lane centers in a predefined world coordinate system. Now, by moving and/or rotating an accumulated object residence map or an in particular filtered object residence map derived therefrom on the basis of a computer, and on the basis of the computer determining a respective degree of correspondence with a world coordinate map, the position and orientation with a predefined degree of correspondence are automatically determined, the actual position and the actual orientation of the sensor are derived from the position, and the position of the object is calibrated accordingly.
本发明涉及一种用于校准道路监测设备的方法,其中,道路监测设备记录预定的监测区域并检测该监测区域中的对象,确定并提供与这些对象相关的对象数据、特别是其位置。在预定义的校准周期内,记录检测到的对象相对于道路监测设备的位置,并由此形成累积的对象驻留地图。另外,存在监测区域的车道或车道中心的世界坐标地图以及这些车道或车道中心在预定义世界坐标系中的位置。现在,通过基于计算机移动和/或旋转累积的对象驻留地图或从其导出的、特别是滤波后的对象驻留地图,并且基于计算机确定与世界坐标地图的相应对应程度,自动确定具有预定义的对应程度的位置和取向,并且从该位置导出传感器的实际位置和实际取向,并相应地校准对象的位置。
