Abstract

The present invention relates to an addressing determination method. By obtaining the calibration position of the light reflected back from the target object detected by the detector at a specified distance, the first sensing distance of the target object within the first time interval, and the first sensing position of the detector, the invention combines an optical model to obtain the first predicted position of the detector at the specified distance based on the first sensing distance and the first sensing position. The invention further determines whether the first predicted position is the same as the calibration position. If the two positions are different, it indicates errors in the process of selecting the region of interest or obtaining the first sensing position within the region of interest.

Dependent claims

An apparatus comprising:

a transmitting end comprising a first emitter, the transmitting end being positioned at a first location, the first emitter being configured to generate a first light signal at a first time and to generate a second light signal at a second time;
a receiving end comprising light detectors, the receiving end being positioned at a second location, the light detectors being configured to receive a first reflected signal at a third time and to receive a second reflected signal at a fourth time, the first reflected signal being associated with the first light signal, the second reflected signal being associated with the second light signal;
and
a processor being configured to:
calculate a first distance using at least a difference between the first time and the third time;
identify a first detector position for detecting the first reflected signal using at least the first distance;
determine a predicted detector position using the first detector position and a difference between the first location and the second location;
calculate a second distance using at least a difference between the second time and the fourth time;
identify a second detector position for detecting the second reflected signal;
and compare the predicted detector position against the second detector position.
