Abstract
A vehicle position measurement system () and method to determine the (relative) position of a vehicle () and an object () are proposed. The system comprises at least two light sources () capable of emitting light and positioned at a predetermined distance () to each other. Furthermore the system comprises at least one detector () capable of measuring the light emitted. The light emitted by the light sources comprises synchronized light source identification codes. The detector is arranged to determine the position of the vehicle () and object () on the basis of a phase-difference measurement between the light originating from the individual light sources () and a comparison phase. The vehicle () may comprise the at least two light sources () and the detector (), while the phase-difference is measured between light reflected from the object () and the comparison phase. Alternatively, the vehicle () may comprise the at least two light sources () while the object () comprises the detector () and the detector is arranged to obtain the comparison phase from the light received from one of the light sources (). The object may be a vehicle.
