The invention discloses a pre-turn-on method and system for an automobile headlamp. The pre-turn-on method comprises the steps that S100, a driving image in front of a current automobile and the distance between the current automobile and a front target are collected; step S200, extracting an image gray value from the obtained driving image; s300, comparing the gray value of the image with a preset gray threshold value; step S400, acquiring the distance between the current vehicle and the front target and the speed of the current vehicle, when a comparison result that the image gray value is smaller than a preset gray threshold value is received, judging the speed range of the speed of the current vehicle, and if the current vehicle is within the speed range and the current vehicle is away from the target by a corresponding preset distance, executing the step S400; a headlamp control command is generated, and the headlamp controller turns on the headlamp based on the headlamp control command. The problem of blind vision caused by switching of light and dark environments of human eyes is solved, and the driving safety is improved.
本发明公开了一种汽车前照灯的预开启方法及系统,包括:步骤S100,采集当前车辆前方的行车图像和当前车辆与前方目标之间的距离;步骤S200,从对获取到的行车图像中提取图像灰度值;步骤S300,基于该图像灰度值与预设灰度阈值比较;步骤S400,获取当前车辆距离前方目标的距离、当前车辆的速度,当收到图像灰度值小于预设灰度阈值这一比较结果时,判断当前车辆的速度所处的速度范围,若当前车辆在该速度范围内,且当前车辆与目标相距相应的预设距离时,产生一前照灯控制命令,前照灯控制器基于该前照灯控制命令开启前照灯。本发明解决人眼明暗环境切换导致的视盲问题,提高行驶安全性。
