This paper describes the associated project of an autonomous helicopter in IIM and USTC. The helicopter requires autonomous flying to the destination, identifying the moving object on land, tracking and keeping the stable position with it. In this case, the helicopter uses the stereo-vision to demarcate the cubic-coordinate of the moving object. If the helicopter is in an emergent or unconstringent state, the GCC (ground control center) will operate it directly. All automation hardware is on-board the helicopter. All elements of the helicopter system are described, including Micropilot, the embedded computer, software system, and stereo-vision system
