The invention discloses a method for protecting pedestrians by a motor vehicle, which comprises the following steps of: acquiring world coordinates of the pedestrians by using a binocular camera, inputting the world coordinates into a social acceptable trajectory model of a generative adversarial network, converting the world coordinates into physical coordinates, predicting continuous physical coordinates of the pedestrians, and comparing adjacent coordinates to calculate the movement direction of the pedestrians. A binocular camera is used for measuring the distance between the pedestrian and the vehicle in the predicted pedestrian physical coordinates, and when the predicted shortest distance is smaller than a threshold value, pedestrian safety air bags below an engine hood and at a front bumper are popped up; the method can quickly and accurately predict the motion trail of the pedestrian, pops up the safety air bag when the pedestrian is predicted to be about to collide with the vehicle, can better protect the safety of the pedestrian, and overcomes the defect that radar ranging is easy to trigger mistakenly.
本发明公开了一种机动车保护行人的方法,利用双目摄像头采集行人的世界坐标,输入到生成性对抗网络的社会可接受轨迹模型转换为物理坐标,并预测连续的行人物理坐标,通过相邻坐标的比较计算行人运动方向,用双目摄像头测量预测的行人物理坐标中行人与车辆的距离,当预测最近距离小于阈值时,弹出发动机舱盖下和前保险杠处的行人安全气囊;本发明能够快速准确预测行人的运动轨迹,当预测到行人与车辆即将碰撞时弹出安全气囊,能够较好地保护行人安全,克服了雷达测距容易误触发的缺陷。
