Building construction material navigation method and system

The invention provides a building construction material navigation method and system, and the method comprises the following steps: a controller obtains building construction material information, the material information comprises the size of a building construction material and a feeding place, and material boundary information is generated based on the size information of the building construction material; planning a walking navigation path of the AGV trolley according to the material boundary information of the building construction materials and a feeding site; under the control of the controller, the mechanical arm clamps the building construction materials in sequence according to the navigation path planning information for stacking operation; and the controller controls the AGV to navigate according to the navigation path and controls the mechanical arm to complete unloading operation. According to the construction material navigation method provided by the embodiment of the invention, not only is t
