In order to improve positioning accuracy and robustness of heavy-duty AGV, a trilateral positioning algorithm strategy based on least square method is proposed. Firstly, working scene of AGV (Automated Guided Vehicle) and shortcomings of traditional positioning methods in application are analyzed; secondly, composition and positioning principle of lidar positioning system are introduced, mathematical models of trilateral positioning algorithm are established under ideal situation and non-ideal situation with errors, and implementation process in the positioning process is analyzed; finally, simulation and test research of lidar positioning strategy are carried out. The simulation and test results show that trilateral positioning algorithm based on least square method has high robustness, anti-interference and positioning accuracy in positioning process, which effectively solves the problem of inaccurate positioning of heavy-duty AGV in movement and improves navigation and positioning technology in this field.
