转速调控下的激光雷达探测器位置像移匹配方法

Key Points

• To address the issue of point deviation in laser radar due to echo delay at high rotational speeds and long distances.
• Developed a mathematical model of OSEDR to relate point deviation to scan mirror speed and target parameters.
• Adjusted the scan mirror speed based on the mathematical model to replace specific long-distance targets for calibration.
• Conducted experiments comparing traditional and proposed methods in a laser radar system.
• Achieved a 96% increase in maximum detection distance, from 1,020 m to 2,000 m at a rate of 50 r/s.
• Confirmed consistent and stable point clouds with no significant gaps within the enhanced detection range.
• Extended the selection range of feedback targets during calibration for mechanical scanning laser radar.
