This paper introduced the principle of laser speckle interferometry displacement measurement and the relocation system based on this measurement method,and proposed a co-evolutionary algorithm for recognition stripe information.Linear dimensionality reduction method was used to reduce the difficulty of searching.Affinity calculation,antibody concentration control and clone selection,crossover and mutation operation methods for stripe corner collaboration algorithm were studied in detail.This method could extract the stripe center line accurately in real time,and recognize the stripe number,distance and angle information.The research shows that the application of the above measurement information to the mobile control platform can meet the requirements of high precision relocation.
