    • The present invention relates to a face detection system for a vehicle. At least one first lighting unit is configured to radiate infrared light onto a left side of a driver's face. At least one second lighting unit is configured to radiate infrared light onto a right side of the driver's face. An image capturing unit separately captures the driver's face onto which the infrared light is radiated from the first and second lighting units. A control unit acquires left and right images of the face from the image capturing unit, and obtains a difference image between the acquired left and right images, thus determining whether the driver is inattentive in looking ahead. The system stably performs the face detection function with no or less effect by external optical environments as well as reduced computational load.
    • 本发明涉及车辆的人脸检测系统。 至少一个第一照明单元被配置为将红外光辐射到驾驶员的脸部的左侧。 至少一个第二照明单元被配置为将红外光辐射到驾驶员的脸部的右侧。 图像拍摄单元分别捕获从第一和第二照明单元辐射红外光的驾驶员面部。 控制单元从摄像单元获取脸部的左右图像,并且获取所获取的左右图像之间的差分图像,从而确定驾驶员在向前看是否不注意。 该系统稳定地执行面部检测功能,其外部光学环境没有或甚至不受影响,并且减少了计算负荷。
