  • Patent number: 12282097
    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.
    Type: Grant

  • Patent number: 11619743
    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, comprising: the active 3D scanner, comprising: a mechanism configured to scan the FOV; at least one energy emitting source configured to emit energy pulses; and the at least one detector; and processing circuitry configured to: obtain information, wherein at least some of designation information is tracker-based designation information that is designated by a user of the system via a tracker that tracks a line-of-sight between the user and the FOV; selectively activate the energy emitting source to emit a subset of the energy pulses, in accordance with the information, including the tracker-based designation information, and in synchronization with the mechanism, to cover the part of the FOV; obtain current readings, from the detector, based on reflections of the subset of the energy pulses; and generate the 3D map based on the current readings.
