Runway vs. Taxiway: Challenges in Automated Line Identification and Notation Approaches
- 调整颜色阈值与区域选择优化原有算法
- 引入CNN分类器后误检率显著降低
- 适合自动驾驶航空系统标注需求
随着自主系统复杂性提升,精准可靠地标记跑道与滑行道线对运行安全至关重要。现有算法如自动化线标识与标注算法(ALINA)在识别滑行道线方面表现良好,但在跑道线识别中面临显著挑战,原因在于线条特征、环境背景及阴影、胎痕和表面状况等干扰因素的差异。本文通过调整颜色阈值与优化感兴趣区域(ROI)选择,改进ALINA以适应跑道场景,虽有一定改善,仍存在将地平线或无关背景误标为跑道线的问题。为此,提出引入名为AssistNet的卷积神经网络(CNN)分类模块,增强检测流程对环境变化的鲁棒性,有效减少误判。本研究不仅揭示了现有方法局限性,还提出了切实可行的改进方案,为自主飞行系统中的自动标注技术发展提供支持。
原文摘要 · Abstract (English)
The increasing complexity of autonomous systems has amplified the need for accurate and reliable labeling of runway and taxiway markings to ensure operational safety. Precise detection and labeling of these markings are critical for tasks such as navigation, landing assistance, and ground control automation. Existing labeling algorithms, like the Automated Line Identification and Notation Algorithm (ALINA), have demonstrated success in identifying taxiway markings but encounter significant challenges when applied to runway markings. This limitation arises due to notable differences in line characteristics, environmental context, and interference from elements such as shadows, tire marks, and varying surface conditions. To address these challenges, we modified ALINA by adjusting color thresholds and refining region of interest (ROI) selection to better suit runway-specific contexts. While these modifications yielded limited improvements, the algorithm still struggled with consistent runway identification, often mislabeling elements such as the horizon or non-relevant background features. This highlighted the need for a more robust solution capable of adapting to diverse visual interferences. In this paper, we propose integrating a classification step using a Convolutional Neural Network (CNN) named AssistNet. By incorporating this classification step, the detection pipeline becomes more resilient to environmental variations and misclassifications. This work not only identifies the challenges but also outlines solutions, paving the way for improved automated labeling techniques essential for autonomous aviation systems.
