Abstract:
An optoelectronic system for collecting three-dimensional data of a scene over a minimum and maximum distance includes illumination modules, each of which is operable to generate a respective light pattern having a respective period. An imaging module is operable to collect a scene-reflected portion of each of the light patterns and is further operable to convert each collected portion into a respective signal set. Each scene-reflected portion is characterized by a respective plurality of ambiguity values and a minimum disparity value, and wherein each signal set corresponds to a respective one of the light patterns. The system includes a processor, and a non-transitory computer-readable medium comprising instructions stored thereon that, when executed by the processor, cause the processor to perform operations for determining a plurality of candidate three-dimensional data sets. Each candidate three-dimensional data set is determined from a respective one of the signal sets. The instructions also cause the processor to perform further operations for determining three-dimensional data of the scene from the plurality of candidate three-dimensional data sets.
