The invention provides a vision-based vehicle steering state judgment method and system. The method comprises the following steps: acquiring multi-dimensional features of a road environment and constructing a dynamic road environment model; performing feature extraction on the road geometric features and the dynamic environment state by adopting a multi-scale convolutional neural network; constructing a path prediction model according to the final road environment feature representation to obtain a predicted path; the adaptability between the road environment and the path is analyzed, and whether adjustment of the expected steering angle is triggered or not is judged; the final corrected steering angle is transmitted to a vehicle control system for actual operation, and it is ensured that the vehicle runs according to the optimal path. The self-adaptive steering state judgment method provided by the invention can fully consider complex road environments and dynamic change factors, not only improves the judgment accuracy, but also enhances the robustness of the system.

    本发明提出基于视觉的车辆转向状态判别方法及系统,方法包括:获取道路环境的多维特征并构建动态的道路环境模型;采用多尺度卷积神经网络对所述道路几何特征和动态环境状态进行特征提取;根据所述最终的道路环境特征表示构建路径预测模型,得到预测路径;对道路环境与路径之间的适配性进行分析,判断是否触发预期转向角度的调整:将最终修正后的转向角度传递给车辆控制系统进行实际操作,确保车辆按照最优路径行驶。本发明提供了一种能够充分考虑复杂道路环境和动态变化因素的自适应转向状态判别方法,不仅提高了判别的准确性,还增强了系统的鲁棒性。
