LIDAR DEVICE AND OPERATING METHOD OF THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18482306 titled 'LIDAR DEVICE AND OPERATING METHOD OF THE SAME
Simplified Explanation
The abstract describes a method for operating a Light Detection and Ranging (LiDAR) device. Here is a simplified explanation of the abstract:
- The method involves receiving signals from reference laser pulses and a main receiving signal.
- The main receiving signal is the one with the highest value at a specific time point.
- A sub-receiving signal included in the receiving signals is corrected based on the maximum value of the main receiving signal.
- The time of flight (ToF) of a laser pulse corresponding to the sub-receiving signal is determined based on the correlation between the corrected value of the sub-receiving signal and the reference signal.
Potential applications of this technology:
- Autonomous vehicles: LiDAR is commonly used in autonomous vehicles for object detection and mapping. This method can improve the accuracy and reliability of LiDAR measurements, enhancing the safety and performance of autonomous vehicles.
- Robotics: LiDAR is also used in various robotic applications, such as navigation and obstacle avoidance. The method can help robots accurately perceive their surroundings and make informed decisions.
- Environmental monitoring: LiDAR can be used for environmental monitoring, such as measuring vegetation height and density. This method can improve the precision of LiDAR measurements, enabling better analysis and understanding of the environment.
Problems solved by this technology:
- Signal correction: The method addresses the issue of correcting the values of sub-receiving signals based on the maximum value of the main receiving signal. This correction helps in obtaining accurate measurements and reducing errors.
- Time of flight determination: The method provides a way to determine the time of flight of laser pulses by correlating the corrected sub-receiving signal with the reference signal. This enables precise distance measurements and object detection.
Benefits of this technology:
- Improved accuracy: By correcting the sub-receiving signals based on the maximum value of the main receiving signal, the method enhances the accuracy of LiDAR measurements.
- Reliable measurements: The correlation between the corrected sub-receiving signal and the reference signal allows for reliable determination of the time of flight, leading to more reliable distance measurements.
- Enhanced performance: The method improves the performance of LiDAR devices by providing a more accurate and reliable measurement technique, enabling better decision-making in various applications.
