The invention discloses a vehicle body height adjusting method based on computer vision. The method comprises the following steps: establishing a traffic light recognition model and pre-training; continuously acquiring vehicle speed information from a bus, and comparing the vehicle speed information with a critical speed; when the vehicle speed reaches the judgment condition, one is added to a corresponding counter, and when the counter reaches a set value, visual detection is executed; when the vehicle speed is above the critical vehicle speed or between two critical vehicle speeds, the counter counts, and when the counter reaches a set value, the three counters in the mode are all reset; the visual detection is used for detecting the environment in front of the vehicle; loading the acquired data to a trained traffic light recognition model for detection, and determining whether to execute height adjustment according to a detection result; if traffic lights are not detected, height adjustment is carried out; and when the traffic signal lamp is detected, the height is not adjusted. The invention has the advantage of avoiding frequent useless height adjustments due to fluctuations in critical speed.

    本发明公开一种基于计算机视觉的车身高度调节方法,建立交通信号灯识别模型及预训练;不断从总线获取车速信息,与临界速度比较;车速达到判断条件时,相应的计数器加一,计数器达到设定值时,执行视觉检测;车速处于临界车速上或者介于两临界车速间时,计数器计数,当计数器达到设定值时,此模式下的三种计数器都清零;视觉检测是对车辆前方的环境进行检测;将获取数据加载至训练好的交通信号灯识别模型进行检测,根据检测结果决定是否执行高度调节;未检测到交通信号灯,进行高度调节;检测到交通信号灯,保持高度不做调节。本发明的优点是避免在临界速度上的波动造成频繁无用的高度调节。
