Abstract

We address the synchronization of a pair of video sequences captured from moving vehicles and the spatial registration of all the temporally corresponding frames. This is necessary in order to perform the pixel wise comparison of a pair of videos. The novelty of our method is that is free from three common restrictions of most previous works. First, it does not require that the two cameras be rigidly fixed to each other, since they can move independently. Second, the temporal correspondence does not assume a linear mapping. Third, it does not rely on the complete trajectories of image features. We present our results in the context of two applications, outdoor surveillance at night and the comparison of vehicle headlights systems.

从移动车辆录制的视频对齐
我们解决了从移动车辆中捕获的一对视频序列的同步和所有时间对应帧的空间注册。这对于执行一对视频的像素比较是必要的。我们的方法的新颖之处在于,它不受大多数以前作品的三个常见限制。首先,它不需要两个摄像机彼此固定,因为它们可以独立移动。其次,时间对应并不假设是线性映射。第三,它不依赖于图像特征的完整轨迹。我们在两个应用的背景下展示我们的结果,夜间户外监视和车辆前灯系统的比较。
