Outdoor GPS navigation and positioning technology is mainly used in all-weather outdoor transport AGV in large scenes. It cooperates with two-dimensional laser radar, three-dimensional laser radar, machine vision, etc. to form a comprehensive environmental perception system to generate high-precision word-number maps on site, so that AGV has the current unmanned vehicles. With the core technology and performance in the field, problems such as outdoor navigation, ground slope restrictions, and severe weather environment restrictions that traditional AGVs cannot handle are easily solved.
