自然场景中的手和手指的跟踪问题已经得到了广泛的关注，使用被动采集视觉系统和计算密集的图像处理。我们目前正在研究一个简单的主动跟踪系统，使用激光二极管，转向镜，和一个单一的非成像检测器，这是能够获得三维坐标在真实的时间，而不需要任何图像处理在所有。从本质上讲，它是一种智能测距扫描仪，它不是在整个视场内连续扫描，而是根据对反向散射信号的实时分析，将其扫描区域限制在一个非常窄的窗口内，该窗口正好是目标的大小。整个设置的复杂性相当于便携式激光条码阅读器，使系统与可穿戴计算机兼容。
The problem of tracking hands and fingers on natural scenes has received much attention using passive acquisition vision systems and computationally intense image processing. We are currently studying a simple active tracking system using a laser diode, steering mirrors, and a single non-imaging detector, which is capable of acquiring three dimensional coordinates in real time without the need of any image processing at all. Essentially, it is a smart rangefinder scanner that instead of continuously scanning over the full field of view restricts its scanning area, on the basis of a real-time analysis of the backscattered signal, to a very narrow window precisely the size of the target. The complexity of the whole setup is equivalent to that of a portable laser-based barcode reader, making the system compatible with wearable computers.
