Range finding method
Abstract:
The present disclosed subject matter relates to a method for measuring the distance of targets in the surroundings by way of a time-of-flight measurement of pulses reflected at said targets, in particular laser pulses, said method comprising: emitting a sequence of transmission pulses having varying pulse intervals, and receiving at least one receive pulse after each one of two different transmission pulses; for each receive pulse: generating a group of M candidate distances, each based on a different transmission pulse among M transmission pulses preceding the receive pulse, wherein each candidate distance is assigned to the corresponding transmission pulse on which it is based; for each candidate distance: determining a weighting value on the basis of at least the closest of the candidate distances assigned to such a transmission pulse which is adjacent to the transmission pulse to which the candidate distance being considered in this determining process is assigned; for each group: selecting the candidate distance with the highest weighting value as the distance measurement value of the receive pulse for which the group was generated.
