Abstract

A computer-implemented method for synchronizing two ranging sensors that are fixed on a vehicle with at least partially overlapping measuring zones comprises receiving a plurality of sensor frames of a first and a second ranging sensor, wherein a sensor frame comprises a point cloud with each point comprising spatial coordinates and a measurement time, selecting a first sensor frame of the first ranging sensor and a second sensor frames of the second ranging sensor based on temporal correlation, identifying dynamic objects in the first sensor frame and identifying dynamic objects in the second sensor frame, wherein identifying a dynamic object comprises clustering points. For identified dynamic objects, the steps of estimating a transformation for mapping the dynamic object in the first sensor frame to the dynamic object in the second sensor frame, determining a timestamp, and calculating a registered object based on the first sensor frame, the second sensor frame, the at least one time stamp and the estimated transformation are performed, wherein the registration of objects is performed locally in a region around the object based on the time stamp. The method further comprises constructing a registered frame by combining the registered objects.
