Micro-motion parameters optical measurement method for conical target

In order to calculate the micro-motion parameters of conical target accurately from an unmanned system, an optical measurement method was proposed. The position and pose parameters were obtained using the target's bottom circle and vertex by monocular vision images. Then the function of position, pose parameters and micro-motion parameters was established according to the kinetic characteristic of aircraft. The experimental results show that the error of procession angle is less than 0.46 degrees, and the error of procession period is less than 0.025s.
