Visual tracking is one of the key components for robots to accomplish a given task in a dynamic environment, especially when independently moving objects are included. This paper proposes an extension of Adaptive Visual Servoing (hereafter, A

Stereo-Vision circuit descr iption, Aug 2002, Ahmad Darabiha This design contains four top level circuits: sv_chip0.vhd, sv_chip1.vhd, sv_chip2.vhd and sv_chip3.vhd each of them built by one Virtex2000E fpga chip. This design is hierarchical an

有很多现成的测距组件包括超声波、红外线、甚至是激光测距仪。这些设备运行的很好，但是对于飞行机器人来说，重量是一个主要考虑因素。一个可行的办法是增加现有组件的功能，并安装在机身上。例如微型空中机器人的有效载荷是100g。它能利用USB连接的摄像头（或mini无线摄像头）执行视觉任务，例如避障等。更好的是，如采用两个摄像头，能提供立体的机器视觉，这样能增强避障性能，因为双镜头提供了视觉深度。但缺点是需要增加另外一个摄像头的重量。这篇文章就是讨论如何利用一个激光笔和一个摄像头来提供一个单镜头机器视觉和
