The utilization of deep learning-based object detection is an effective
approach to assist visually impaired individuals in avoiding obstacles. In this
paper, we implemented seven different YOLO object detection models
\textit{viz}., YOLO-NAS (small, medium, large), YOLOv8, YOLOv7, YOLOv6, and
YOLOv5 and performed comprehensive evaluation with carefully tuned
hyperparameters, to analyze how these models performed on images containing
common daily-life objects presented on roads and sidewalks. After a systematic
investigation, YOLOv8 was found to be the best model, which reached a precision
of $80\%$ and a recall of $68.2\%$ on a well-known Obstacle Dataset which
includes images from VOC dataset, COCO dataset, and TT100K dataset along with
images collected by the researchers in the field. Despite being the latest
model and demonstrating better performance in many other applications, YOLO-NAS
was found to be suboptimal for the obstacle detection task.

深度学习目标检测在帮助视力受损者避开障碍物方面是一种有效的方法，本文通过实现并评估七种不同的 YOLO 目标检测模型（YOLO-NAS，YOLOv8，YOLOv7，YOLOv6 和 YOLOv5）来分析这些模型在道路和人行道上常见物体的图像上的表现，并发现 YOLOv8 是最佳模型，其在包含 VOC、COCO 和 TT100K 数据集的 Obstacle 数据集上表现出 80% 的精确度和 68.2% 的召回率，尽管 YOLO-NAS 是最新的模型，在其他应用中表现更好，但对于障碍物检测任务来说并不理想。
