Abstract: A system and method for generating a focused three-dimensional (3D) point cloud is disclosed. A respective 3D point cloud is generated based on returns of a respective sequence of energy pulses that is emitted towards one or more regions-of-interest (ROIs) within a field-of-view (FOV) during a respective scan of the FOV, the returns including one or more secondary returns from one or more points within the FOV. During an additional scan of the FOV, subsequent to the respective scan, an additional sequence of energy pulses is emitted to generate a focused 3D point cloud that includes additional information regarding one or more selected points of the points associated with the secondary returns relative to the respective 3D point cloud.

Abstract: A system for generating a three-dimensional (3D) map of part of a field-of-view (FOV) of at least one detector of an active 3D scanner, the system comprising: the active 3D scanner, comprising: a scanning mechanism configured to scan the FOV; at least one energy emitting source configured to emit energy pulses, in synchronization with the scanning mechanism, to cover the FOV; and the at least one detector: and processing circuitry configured to: obtain mapping designation information independent of past readings obtained by the at least one detector, if any; selectively activate the energy emitting source to emit only a subset of the energy pulses, in accordance with the mapping designation information, to cover the part of the FOV; obtain current readings, from the at least one detector, based on reflections of the subset of the energy pulses; and generate the 3D map based on the current readings.
