摘要:
 为缓解社会老龄化压力和解决子女照顾老人的精力不足等问题,设计一种基于深度相机的高准确性和低误报性的人体跌倒检测系统。该系统使用RGB相机和红外IR相机获取标定后的老人所在环境的3D图像,并利用深度卷积神经网络提取人体的多个关节点位置,最后基于多个连续帧之间人体关节点的运动变化特征和3D场景特征相结合的方法综合判定老人是否发生跌倒行为。测试实验结果表明该系统能有效地检测到人体的跌倒行为,具有十分优良的鲁棒性。
Abstract:
 Abstract: A fall detection system using a depth camera with a high accuracy and a low false alarm rate is designed to ease the pressure of children who are lacking the energy to take care of their elderly parents and alleviate the pressure caused by the increasingly aging. In this scheme, calibrated RGB camera and infra red camera are used to obtain the 3D image of the surroundings of the elderly, and convolutional neural network is used to extract the multijoint positions. Whether fall occurs is determined by the comprehensive consideration of the 3D information of surrounding and the space-time characteristics of human joints between video frames. The test results show that the proposed fall detection system has a high accuracy and superior roubst for the elderly.
