The invention relates to a bus epidemic prevention system with mask recognition and temperature measurement functions, and the system is additionally provided with the mask recognition function, so that the workload of a driver is reduced. Meanwhile, whether the mask is worn or not is measured one by one, and the purpose of accurate supervision is achieved. In addition, identification of forehead shielding objects is added, so that the system can accurately obtain the forehead temperature, and the temperature measurement accuracy and the temperature measurement success probability are improved. The system obtains a face picture through the camera for processing and recognition, on one hand, the positions of the nose and the mouth are recognized, and therefore whether a passenger wears a mask or not is judged; on the other hand, the positions of eyebrows and eyebrows are identified, so that whether the forehead of the passenger has a shelter is judged. Therefore, the accuracy of temperature measurement is improved.
本发明涉及一种兼有口罩识别和测温功能的公交车防疫系统,系统增设口罩识别功能,减轻司机工作量。同时一对一测量是否佩戴口罩,达到监管精准到位的目的。本发明还增加对额头遮蔽物的识别,使得系统能准确获取额头温度,提高测温的准确度以及测温成功的概率。系统通过摄像头获取人脸图片进行处理识别,一方面识别出鼻子和嘴巴的位置,从而判断出乘客是否佩戴口罩;另一方面识别出眉毛和眉心的位置,从而判断出乘客额头是否有遮蔽物。从而提高了温度测量的精准度。
