The invention discloses a cascade model-based passenger safety belt alarm method and system. The method comprises the following steps of: acquiring a video stream in a cabin through a camera; inputting the video stream in the cabin into a human body detection model in a preset cascade model, obtaining a human body detection result, judging whether a human body is detected or not, if not, ending the process, and otherwise, carrying out subsequent steps; inputting the human body detection result into a human body key point detection model in the cascade model, obtaining the human body key point detection result, judging whether the human face posture meets a preset requirement or not, if not, returning to the previous step, and if yes, carrying out subsequent steps; determining a passenger position according to a human body key point detection result, and determining a safety belt detection input image area; carrying out safety belt wearing detection on the safety belt detection input image area, and obtaining the safety belt wearing condition of each seat in combination with the position of the passenger; and judging whether to give an alarm according to the safety belt wearing condition of each seat. The method needs less calculation power and is high in accuracy.
本发明公开了一种基于级联模型的乘员安全带报警方法及系统,所述方法包括:通过摄像头获取座舱内视频流;将座舱内视频流输入预设的级联模型中的人体检测模型,得到人体检测结果并判断是否检测到人体,若未检测到人体则流程结束,反之进行后续步骤;将人体检测结果输入级联模型中的人体关键点检测模型,得到人体关键点检测结果并判断人脸姿态是否符合预设要求,若不符合则返回上一步骤,若符合则进行后续步骤;根据人体关键点检测结果确定乘员位置,并确定安全带检测输入图像区域;对安全带检测输入图像区域进行安全带佩戴检测,结合乘员位置获得各座位的安全带佩戴情况;根据各座位安全带佩戴情况判断是否报警。该方法所需算力较少,准确率高。
