本文提出了一种逐帧间歇跟踪的概念，以实现视频拍摄快速运动场景时的无运动模糊和高亮度图像。在我们的跟踪概念中，根据相机的快门打开或关闭状态，以数百赫兹交替应用两种控制方法。当快门打开时，图像中目标的速度被控制在零，并传输视觉反馈以实现运动模糊减少，当快门关闭时，相机返回到其原始位置。我们开发了一个原型，我们的运动模糊的视频拍摄系统，其中包括我们的跟踪方法实现了一个高速的两个自由度的跟踪视觉平台，通过使用高速视频处理，以减少运动模糊控制摄像机视图的平移和倾斜方向。我们的无运动模糊视频拍摄系统可以以125 fps的速度拍摄灰度为512 ×512的图像，并具有逐帧间歇跟踪功能。实验结果验证了它的性能为几个视频序列的快速运动物体。在实验中，在不减少曝光时间的情况下，我们的方法减少了由运动模糊引起的图像退化。
In this paper, a concept of frame-by-frame intermittent tracking to achieve motion-blur-free and high-brightness images when video shooting fast moving scenes is proposed. In our tracking concept, two control methods are applied alternately at hundreds of hertz, according to the open or closed shutter state of the camera. When the shutter is open, the target’s speed in images is controlled at zero and visual feedback is transmitted to achieve motion blur reduction, and when the shutter is closed, the camera returns to its home position. We developed a prototype of our motion-blur-free video shooting system, which consists of our tracking method implemented on a high-speed two degrees-of-freedom tracking vision platform that controls the pan and tilt directions of the camera view by using high-speed video processing in order to reduce motion blur. Our motion-blur-free video shooting system can capture gray-level $$512\times 512$$512×512 images at 125 fps with frame-by-frame intermittent tracking. Its performance is verified by the experimental results for several video sequences of fast moving objects. In the experiments, without a decrease in the exposure times our method reduced image degradation caused by motion blur.
