Abstract
A method of using an optical TOF module to determine distance to an object. The method includes acquiring signals in the TOF module indicative of distance to the object, using a first algorithm to provide an output indicative of the distance to the object based on the acquired signals, using at least one second different algorithm to provide an output indicative of the distance to the object based on the acquired signals, and combining the outputs of the first and at least one second algorithms to obtain an improved estimate of the distance to the object. In some implementations, each of the first and at least one second algorithms further provides an output representing a respective confidence level indicative of how accurately distance to the object has been extracted by the particular algorithm.
