The invention relates to a vehicle collision early warning method and device, electronic equipment and a storage medium, and the method comprises the steps: multiplying an image feature map by an attention weight to obtain an adjusted image feature map, and inputting the adjusted image feature map into a preset classification model to obtain a classification result, the classification efficiency of the Internet of Vehicles and the social vehicles can be improved, and the classification accuracy is improved; the driving data of the vehicle of the Internet of Vehicles are obtained by accessing the data of the Internet of Vehicles, and the driving data of social vehicles are calculated according to the acquisition frequency of the coordinate information and the driving image information, so that richer driving data of surrounding vehicles can be obtained; trajectory prediction is carried out according to the driving data of the vehicle of the Internet of Vehicles and the driving data of the social vehicles to obtain the predicted trajectory of the second vehicle, and collision early warning is carried out under the condition that the predicted trajectory and the driving trajectory meet the early warning condition, so that the accuracy of vehicle collision risk pre-judgment can be improved based on more efficient trajectory prediction.

    本公开涉及一种车辆碰撞预警方法、装置、电子设备及存储介质,上述方法通过将图像特征图与注意力权重相乘得到调整后的图像特征图,并将调整后的图像特征图输入预设分类模型得到分类结果,能够提高对车联网车辆及社会车辆的分类效率,提高分类准确度;通过访问车联网数据获取车联网车辆的行车数据,并根据坐标信息及行车图像信息的采集频率计算社会车辆的行车数据,能够获取更丰富的周围车辆行车数据;通过根据车联网车辆和社会车辆各自的行车数据进行轨迹预测得到第二车辆的预测轨迹,并在预测轨迹与行驶轨迹满足预警条件的情况下进行碰撞预警,能够基于更高效的轨迹预测从而提高车辆碰撞风险预判的准确性。
