The invention provides an alarm method and system for people left in an automobile, and relates to the technical field of automobiles. When a driver stops, an automobile door is locked, and the environment in the automobile reaches a preset value, a heat source in the automobile is scanned and detected through a human body recognition sensing detection algorithm; if the temperature distribution variances of two or more continuous frames are all greater than a set temperature variance threshold, it is regarded that someone is left in the vehicle at the moment, sound-light alarm is carried out through a vehicle-mounted double-flashing light and a horn, after the alarm is overtime, a vehicle window falls for ventilation, an air conditioner starts for refrigeration, alarm information is sent to a mobile phone of a vehicle owner, and the vehicle owner is reminded of the vehicle. Human body heat source information is collected through the child missing infrared recognition sensing module, early warning prompting and control processing are achieved after set judgment conditions are met, trapped children in a vehicle are rescued in time, casualty accidents are avoided, meanwhile, temperature dot matrixes are collected, and the problems of privacy protection, illumination changes, shadows and night visibility are solved.
本发明提出了一种汽车内遗留人员报警方法及系统,涉及汽车技术领域,当驾驶员停车,车门锁闭,车内环境达到预设值,通过人体识别感知检测算法对车内热源进行扫描探测,若前后连续两帧或者两帧以上的温度分布方差均大于设定温度方差阈值,则视为车内此时有人遗留在车上,通过车载双闪灯和喇叭进行声光报警,报警超时后,车窗降落通风和空调开启制冷,将报警信息发送到车主手机上,本发明通过儿童遗落红外识别感知模块对人体热源信息进行采集,满足设定判断条件后实现预警提示和控制处理,及时解救车内被困儿童避免伤亡事故的发生,同时采集到的是温度点阵,解决了隐私保护、光照变化、阴影和夜间可视性问题。
