A recently granted patent (Publication Number: US11906629B2) discloses a method for optical distance measurement that involves emitting measuring pulses, receiving reflected pulses, and determining 2D and 3D information for a measuring region. The method includes two phases within a frame of measurement. In the first phase, 2D information is determined for a portion of the measuring region, and regions of interest are identified. In the second phase, 3D information is determined based on the assigned receiving elements and evaluating units, with a focus on regions of interest. The method optimizes the allocation of resources and processing power based on the identified regions of interest, enhancing the efficiency and accuracy of the distance measurement process.

Furthermore, the patent also describes a device implementing the method for optical distance measurement. The device includes transmitting and receiving units, as well as evaluating units for processing the received pulses. By following the method's two-phase approach and assigning elements and units based on regions of interest, the device can effectively capture and analyze data to generate precise 2D and 3D information about the measuring region. The device's design allows for efficient utilization of resources, with a particular emphasis on optimizing the time budget for each phase. Overall, the patented method and device offer a sophisticated solution for optical distance measurement, combining advanced technology with strategic data processing techniques to improve measurement accuracy and efficiency.
