Abstract

Electromagnetic positioning technology based on excitation coils can achieve rapid and high precision positioning in a short distance area. However, the efficiency and accuracy are low in a long distance area. In order to improve the efficiency of the long distance magnetic positioning, a magnetic positioning method based on homotopy algorithm is proposed. Three orthogonal coils are excited separately to generate the magnetic field, and a three-axis fluxgate sensor is mounted on the target object to measure the magnetic field. Then the homotopy algorithm is chosen to solve the nonlinear equations of the magnetic field. The effectiveness of the algorithm is verified by experiments. The algorithm runs no more than 1 second at a time and the maximum positioning error does not exceed 0.5 meters within four meters.
