The invention relates to a feature big data extraction device, and the device comprises region extraction equipment which is used for enabling all hair pixels in a to-be-processed image to be fitted into a plurality of hair regions through employing the pixels, of which the gray values are in a preset hair gray range, as the hair pixels; the grade detection equipment is used for determining a corresponding hair disorder grade based on the edge irregularity degree of each hair area, and the higher the edge irregularity degree of each hair area is, the higher the corresponding hair disorder grade is; and the strength adjusting equipment is used for adjusting the exchange strength of the air exchange equipment based on the plurality of hair disorder levels corresponding to the plurality of hair areas. The feature big data extraction device is compact in structure and effective in control. Due to the fact that the cleanliness of the personnel is determined according to the messy degree ofthe hair of each personnel in the train carriage, the exchange strength of the air exchange equipment is controlled, and the situation that the internal environment of the carriage is not well managedis avoided.
本发明涉及一种特征大数据提取装置,包括:区域提取设备,用于将灰度值落在预设头发灰度范围内的像素点作为头发像素点,将待处理图像中所有的头发像素点拟合成多个头发区域;等级检测设备,用于基于每一个头发区域的边缘不规则程度确定对应的头发杂乱等级,每一个头发区域的边缘不规则程度越高,对应的头发杂乱等级越高;强度调节设备,用于基于所述多个头发区域分别对应的多个头发杂乱等级对空气交换设备的交换强度进行调节。本发明的特征大数据提取装置结构紧凑、控制有效。由于根据火车车厢内每一个人员的发体的杂乱程度确定人员的干净程度,进而控制空气交换设备的交换强度,从而避免出现车厢内部环境管理不善的情况。
