Method and system for calculating theoretical stone block rate of facing stone

The invention relates to the technical field of facing stone exploration, and discloses a facing stone theoretical stone block rate calculation method and a facing stone theoretical stone block rate calculation system, and the method comprises the following steps: inputting stone measuring point and measuring area information; generating a raw material rate superposition graph; according to a maximum rectangle algorithm in the polygonal region, intercepting a quarry stone; and counting and summarizing calculation results to form a final rough stone block rate. The system comprises a data acquisition module, a superimposed graph generation module, a quarry stone interception module and a statistical calculation module. According to the calculation method and drawing system for the theoretical stone block rate of the facing stone based on the maximum rectangle algorithm in any direction in the polygon, a superimposed graph can be automatically generated through a computer, the computer is manually assisted to s
