Abstract
The present invention relates to a reading device for determining a signal propagation time of a light pulse between a lidar transmission unit and a lidar receiving unit of a lidar measuring device in a focal plane array arrangement, comprising: an input interface for receiving detections from multiple sensor elements of the lidar receiving unit, said sensor elements being arranged in a macrocell paired with a transmission element of the lidar transmission unit; a weighting unit for determining a respective individual weighting parameter for each of the plurality of sensor elements, said weighting parameter being based on a signal-to-noise ratio of the sensor element; a summation unit for generating a histogram with an allocation of the detections to the detection times of the detections, said summation unit being configured to weight the detections on the basis of the individual weighting parameters; a propagation time unit for determining the signal propagation time on the basis of the generated histogram; and an output unit for outputting the signal propagation time. The invention additionally relates to a method for determining a signal propagation time and to a lidar measuring device in a focal plane array arrangement for detecting objects in a surroundings of a vehicle.
