摘　　要：为保障汽车头枕的驾乘舒适性和防碰撞安全性,设计一款基于图像识别的高度可自适应调整的汽车头枕系统.该系统使用摄像头采集驾乘人员图像,并利用灰度化处理、直方图均衡化、中值滤波处理图像,提高图像质量.选用哈尔特征的Adaboost算法实现人脸特征提取,训练组成级联分类器,实现人脸检测和定位.通过解析几何列出了头枕调整高度的计算公式,并采用步进电机控制程序与人脸检测及高度计算模块数据通信,实现汽车头枕高度自适应调整.In order to ensure the driving comfort and collision safety of the car headrest,a highly adaptively adjustable car headrest system based on image recognition is designed.The system uses a camera to collect images of drivers and passengers and uses grayscale processing,histogram equalization,and median filtering to process the images to improve image quality.The adaboost algorithm with Haar features is used to extract facial features,and a cascade classifier is trained to realize face detection and localization.The calculation formula of the headrest adjustment height is listed through analytical geometry,and the stepper motor control program communicates with the face detection and height calculation module to realize the adaptive adjustment of the headrest height in the vehicle.
