Abstract

The invention discloses an intelligent vehicle lamp system with a driver eyesight following function and a control method for the intelligent vehicle lamp system, and belongs to the technical field of active safety of automobiles. The system comprises a vehicle lamp motor, and driver image acquisition equipment is connected with a control system through a serial communication data line; the control system is connected with a motor controller and a signal acquisition unit through a controller area network (CAN) bus respectively; the vehicle lamp motor is connected with the motor controller; and an angle sensor is arranged on an output shaft of the vehicle lamp motor and is connected with the signal acquisition unit. The method comprises the following steps of: acquiring a face image, filtering the image, and reducing noise of the image; performing binarization partition on the image, removing a background image, detecting the edge of the image, and positioning outlines of a face and double eyes; calculating the turn angle of the face, and positioning a pupil to determine turn angles of eyeballs and eyesight; and correcting a control signal in real time based on performance index (PI) control according to the deviation between an actual measurement feedback valve of the turn angle of a vehicle lamp and the turn angle of the eyesight of a driver so as to ensure that the actual turn angle of the vehicle lamp is coincided with the turn angle of the eyesight of the driver.

Description

technical field [0001] The invention belongs to the technical field of automobile active safety, and in particular relates to an intelligent car light system with the function of following the driver's gaze and a control method thereof. driving safety. Background technique [0002] When driving at night, the driver needs to rely on the lights to identify the road environment, so as to control the safe driving of the vehicle; however, most of the ordinary lights installed on modern cars can only be projected straight ahead, with only a fixed irradiation range. When the vehicle is driving at an unfamiliar intersection, the driver often pays more attention to the pedestrians on the side of the vehicle and the road environment; in addition, similar situations will also occur in dark and narrow parking lots and other environments, such as figure 1 shown. In these cases, the light projected straight ahead obviously cannot meet the driver's observation needs, and the driver can o...
