Research Of Three Dimensions Optics Location Methods

An autonomous location-tracking ability is a major basic performance for locating sensor systems to navigate an autonomous mobile vehicle on time. It can used to make movement deciding and path planning based on a task. So in recent years, many kinds of positioning system and locating methods are researched.In these locating methods, laser global location and vision tech are new ones. This paper is based on mobile robot of Robotics Laboratory of Chinese Academy of Science and studies the location problem of intelligent navigation system of autonomous mobile robot (AMR).In the first part of this paper we present a laser scanning location algorithm based on least square algorithm using landmarks. Then successively, we give the principle of the landmarks option and position recovery algorithm. In the end, the work process of algorithm is given.In the following part of this paper a new space-location vision system based on one-dimensional cameras is presented. In this paper, the measurement methods based on space geometry theory and the structure of the system are introduced. The line-correspondences method is used to calibrate the camera systems. Last, the experiments were given to show the efficiency of this system on position measurement of space targets. On this base, the calibration methods based artificial neural networks introduced. The experiments were given to show the efficiency of this method.
