Lidar system for determining range-wrapped pixels
A lidar system has been granted a patent (Publication Number: US11971484B2) that includes a light source emitting optical pulses at different pulse intervals (PIs), a receiver detecting input optical pulses, and a processor generating pixels associated with PIs to determine range-wrapping of pixels based on a pixel-disparity metric (PDM). The system analyzes nearby pixels along a scan line to assess the likelihood of range-wrapping, with the PDM indicating the probability of a pixel being range-wrapped. The patent also covers the application of this lidar system in vehicles, where it can aid in detecting targets based on scattered light from emitted optical pulses, ensuring accurate distance measurements and obstacle detection.
The lidar system's innovative approach to pixel analysis and range-wrapping assessment, as outlined in the granted patent, offers a sophisticated solution for accurate distance measurement and target detection. By utilizing different PIs and the PDM metric, the system can effectively determine if a pixel is range-wrapped, enhancing the reliability of lidar data in various applications. The inclusion of this technology in vehicles further highlights its potential impact on improving safety and efficiency by providing precise obstacle detection capabilities based on scattered light from emitted pulses. Overall, the patented lidar system represents a significant advancement in the field of range-finding technology, with potential implications for enhancing autonomous driving systems and other applications requiring precise distance measurements.
