基于激光雷达的室内跌倒检测系统设计与实践

Design and Practice of Indoor Fall Detection System Based on Lidar

针对传统跌倒检测系统易泄露隐私、需穿戴等问题,提出一种室内跌倒检测算法以及边界检测算法,利用ROS平台,设计并实现了基于激光雷达的室内跌倒检测系统。该系统测距精度高、实时性好,可以快速准确地识别老人跌倒,具备自动报警和解除报警功能,同时解决了边界上的误报问题,提高了系统可靠性。

In order to solve the problems of leakage of private and inconvenience in wearing devices in applying traditional methods,the paper proposes a falling-down detection algorithm and detection-border recognition algorithm.The system is running based on the sensor lidar and robot operating system,which is known as ROS.The algorithm has the merits of fast falling-down detection.Furthermore,the system is equipped with the auto-alarm and alarm-dismiss functions.At last,the specific situation of misidentification while the person is going through the door is processed,which enhance the reliability of the detection system.
