The invention discloses a face recognition system for high-speed rail air conditioner adjustment. Images of passengers in a compartment are shot through a camera installed in the compartment of the high-speed rail; the method comprises the following steps: recognizing a human face from an image through a computer, extracting key features of the human face, counting the number and types of passengers in each region, acquiring the air volume required by the region according to a pre-established temperature field model, and sending a control signal for adjusting the opening degree and temperatureof an air valve to an intelligent air valve to automatically adjust an air conditioner in a carriage. The mode that a traditional high-speed rail air conditioner system is adjusted according to a temperature sensor is changed, the number change and different types of passengers are considered, accurate regional temperature adjustment is achieved for the air conditioner, and therefore the purposesof energy saving and comfort are achieved.

    本发明公开了一种面向高铁空调调节的人脸识别系统,通过安装在高铁车厢中的摄像头拍摄车厢内乘客的图像,通过计算机从图像中识别人脸,提取人脸部的关键特征,统计各区域内的乘客数量和乘客类别,然后依据预先建立的温度场模型获取区域所需要的风量,发送调节风阀开度和温度的控制信号给智能风阀,进行车厢内空调自动调节。本发明改变传统高铁空调系统依据温度传感器调节的方式,考虑了乘客的数量变化和不同类别,对空调实现较为精确的区域温度调节,从而达到节能和舒适的目的。
