论文摘要
在视频监视和汽车应用中,经常使用所谓的鱼眼摄像机来捕获非常广泛的视角。由于这种相机取决于经典的观点投影截然不同的投影,因此所得的鱼眼图像和视频数据相应地表现出非均方线图像特征。但是,典型的图像和视频处理算法并不是为这些鱼眼特征而设计的。为了开发和评估专门适用于鱼眼图像和视频的算法,本文介绍了相应的测试数据集。这些序列的第一个序列是在作者对鱼眼视频的运动估计工作中生成的,并且逐渐添加了进一步的序列,以创建更广泛的收藏。现在,数据集包括合成生成的鱼眼序列,从简单的图案到更复杂的场景,以及使用实际的鱼眼相机捕获的鱼眼视频序列。对于合成序列,可以提供有关所采用镜头的精确信息,从而促进对任何适应算法的验证和评估。对于现实世界序列,我们提供校准数据以及在采集过程中使用的设置。这些序列可通过www.lms.lnt.de/fisheyedataset/免费获得。
In video surveillance as well as automotive applications, so-called fisheye cameras are often employed to capture a very wide angle of view. As such cameras depend on projections quite different from the classical perspective projection, the resulting fisheye image and video data correspondingly exhibits non-rectilinear image characteristics. Typical image and video processing algorithms, however, are not designed for these fisheye characteristics. To be able to develop and evaluate algorithms specifically adapted to fisheye images and videos, a corresponding test data set is therefore introduced in this paper. The first of those sequences were generated during the authors' own work on motion estimation for fish-eye videos and further sequences have gradually been added to create a more extensive collection. The data set now comprises synthetically generated fisheye sequences, ranging from simple patterns to more complex scenes, as well as fisheye video sequences captured with an actual fisheye camera. For the synthetic sequences, exact information on the lens employed is available, thus facilitating both verification and evaluation of any adapted algorithms. For the real-world sequences, we provide calibration data as well as the settings used during acquisition. The sequences are freely available via www.lms.lnt.de/fisheyedataset/.
