METHOD AND DEVICE OF DISTANCE MEASUREMENT BY TIME-OF-FLIGHT CALCULATION WITH WRAPAROUND
Abstract:
The present disclosure concerns a method of measuring the distance between a device and an object comprising the steps of determination of a first estimated distance based on the time of flight of first light pulses having a first period; determination of a second estimated distance based on the time of flight of second light pulses having a second period different from the first period; determination based on the interval between the first and second estimated distances of whether the device is in a wraparound area among wraparound areas; and if the device is in a wraparound area among wraparound areas, adding to the first estimated distance a compensation having its value depending on the wraparound area.
