论文摘要
自动驾驶的车辆和自动地面机器人需要一种可靠，准确的方法来分析周围环境的遍历以进行安全导航。本文提出并评估了一种基于机器学习的遍历性分析方法，该方法将基于SVM分类器的混合方法中的几何特征与基于外观的特征相结合。特别是，我们表明，整合一组新的几何和视觉特征并专注于重要的实施细节，可以显着提高性能和可靠性。已提出的方法已与最先进的深度学习方法进行了比较。在不同复杂性的情况下，它的精度为89.2％，表明其有效性和鲁棒性。该方法在CPU上完全运行，并且相对于其他方法，可以达到可比的结果，运行速度更快，并且需要更少的硬件资源。
Self-driving vehicles and autonomous ground robots require a reliable and accurate method to analyze the traversability of the surrounding environment for safe navigation. This paper proposes and evaluates a real-time machine learning-based Traversability Analysis method that combines geometric features with appearance-based features in a hybrid approach based on a SVM classifier. In particular, we show that integrating a new set of geometric and visual features and focusing on important implementation details enables a noticeable boost in performance and reliability. The proposed approach has been compared with state-of-the-art Deep Learning approaches on a public dataset of outdoor driving scenarios. It reaches an accuracy of 89.2% in scenarios of varying complexity, demonstrating its effectiveness and robustness. The method runs fully on CPU and reaches comparable results with respect to the other methods, operates faster, and requires fewer hardware resources.
