The invention relates to a non-driving behavior risk protection method and system based on driving posture recognition, and the method comprises the steps: receiving video data of a driver, carrying out the joint point recognition, and obtaining the driving posture of the driver at each moment; performing similarity comparison on the driving posture of the driver at each moment and a standard driving posture, and calculating the degree of dislocation, so as to perform safety scoring on the degree of dislocation; non-driving behavior duration is determined according to a posture similarity threshold value, and corresponding off-location time is determined according to safety measure reserved time, so that the off-location time is compared with human body reaction demand time to perform safety scoring on the off-location time; and comprehensively considering the safety scoring result of the off-location degree and the safety scoring result of the corresponding off-location time by adopting a matrix scoring mode, and determining a risk degree grade scoring result, thereby executing a corresponding safety protection strategy. Compared with the prior art, the man-machine interaction experience and efficiency of the intelligent driving vehicle can be greatly improved, false alarms are reduced, and the safety of the vehicle is improved.
本发明涉及一种基于驾驶姿态识别的非驾驶行为风险防护方法和系统,方法包括:接收驾驶员视频数据,进行关节点识别,获取各个时刻驾驶员的驾驶姿态;将各个时刻驾驶员的驾驶姿态与标准驾驶姿态进行相似度比较,计算离位度,从而进行离位度的安全打分;根据姿态相似度阈值确定非驾驶行为持续时长,并根据安全措施预留时间,确定对应的离位时间,以与人体反应需求时间对比进行离位时间的安全打分;采用矩阵式打分的方式综合考虑离位度的安全打分结果和对应离位时间的安全打分结果,确定风险度等级打分结果,从而执行对应的安全防护策略。与现有技术相比,本发明可以极大的提升智能驾驶车辆人机交互的体验和效率,减少误报,并提升车辆安全性。
