Symphony Lake数据集，来自无人驾驶地面车辆的500多万张图像捕捉了非结构化的自然环境

Symphony Lake Dataset consists of 121 visual surveys of a lakeshore over more than three years in Metz, France. Unique from roadway datasets, it adds breadth to a space at a time when larger and more diverse datasets are needed to train data hungry machine learning methods. Over 5 million images from an unmanned surface vehicle capture the unstructured, natural environment as it evolved over time. Significant variation in appearance is present on time scales of weeks, seasons, and years. Success in this space may demonstrate advancements in perception, SLAM, and environment monitoring. This is just a portion of the dataset covering the downsampled images recorded from the vehicle. They are organized by directories representing the month and datestamps and images containing the different positions and angles captured.
