The invention discloses a lane congestion prompting method, a lane congestion prompting system and a terminal. The method comprises the following steps: acquiring at least one frame of lane image; for any lane image, identifying a vehicle frame for representing each vehicle and a motion state of each vehicle from the any lane image; according to the overlapping condition of adjacent target vehicle frames in any lane image, determining the vehicle congestion length corresponding to the any lane image; in the at least one frame of lane image, determining a first number of lane images of which the lane congestion lengths meet a preset condition; and determining the congestion duration according to the determined first number, and carrying out congestion prompting according to the congestion duration. A vehicle motion state is determined, and a target frame corresponding to a static vehicle is identified; the position relation of the adjacent vehicles can be more accurately determined and the vehicle congestion length can be determined by using the overlapping condition of the adjacent target frames; congestion prompting is carried out according to the congestion duration, and the accuracy of congestion prompting is improved.
本申请公开了一种车道拥堵提示方法、车道拥堵提示系统及终端,该方法包括:获取至少一帧车道图像;针对任意车道图像,从该任意车道图像中识别出用于表示各车辆的车辆框、以及各车辆运动状态;依据任意车道图像中相邻目标车辆框的重叠情况,确定该任意车道图像对应的车辆拥堵长度;在至少一帧车道图像中,确定出车道拥堵长度满足预设条件的车道图像的第一数量;依据确定出的第一数量,确定拥堵持续时间,并依据拥堵持续时间进行拥堵提示。通过确定车辆运动状态,及识别静止车辆对应的目标框;利用相邻目标框重叠情况能更加精确确定相邻车辆的位置关系并确定车辆拥堵长度;根据拥堵持续时间进行拥堵提示,提升拥堵提示的准确性。
