信頼性のあるPSISベースセクションランキングランキングは、人間のドライバーと自動運転システムの両方にとって重要ですが、その状態はまだ手動検査で一般的に評価されています。既存の自動運転データセットは主にランキング検出とシーン理解をサポートし、通常は、GPS対応のダッシュカムアプリケーションを使用して、メンテナンス指向のラベルが欠けています。この研究では、地理的に参照されたスマートフォンダッシュカムデータセットとランキング品質評価のためのベースラインフレームワークを提示します。パイロットデータセットには、南テキサスで収集された63,839のロードフェアフレームが含まれています。3339のフレームのサブセットは、OpenStreetMapSIによるランキングランキングランキングランキング

Abstract

Reliable lane markings are important for both human drivers and automated driving systems, but their condition is still commonly assessed through manual inspection. Existing autonomous-driving datasets primarily support lane detection and scene understanding and usually lack maintenance-oriented labels for lane-marking visibility, continuity, or degradation. In this study, we present a geo-referenced smartphone dashcam dataset and baseline framework for lane-marking quality assessment. The dataset contains 63,839 road-facing frames collected across South Texas using a GPS-enabled dashcam application. A subset of 3,339 frames is matched with OpenStreetMap-derived lane-count labels, which are used as weak supervision for lane-count regression and map-consistency evaluation. We propose three lane-quality measures: Contrast Stability Index (CSI), which captures lane-background contrast using Laplacian responses; Line Continuity Ratio (LCR), which estimates structural continuity using edge and Hough-line evidence; and Regression Lane Confidence Score (RLCS), which measures agreement between predicted and map-derived lane counts on matched frames. The baseline prediction models attained strong performance, with CSI (MAE $0.039$, $R^2=0.97$) and LCR (MAE $0.093$, $R^2=0.84$). Notably, CSI and LCR are no-reference, segmentation-derived quality metrics that can be computed without dense human labels. In a pilot validation using 50 human-ranked images, these proposed lane-specific metrics show stronger rank agreement with human lane-quality ordering (e.g., Spearman's $ρ=0.7316$ and Kendall's $τ=0.5472$ for LCR) than general image-quality measures such as PSNR, SSIM, BRISQUE, NIQE, and LPIPS. We believe the dataset, metrics, and baseline provide an initial step toward scalable, low-cost, location-aware lane-marking quality assessment.
