The invention discloses a population activity quantity extraction method and system based on a Baidu thermodynamic diagram and a medium. The method comprises the following steps: acquiring Baidu thermodynamic diagram information; projecting the Baidu thermodynamic diagram information to the two-dimensional coordinate matrix to obtain two-dimensional thermodynamic diagram information; preprocessing the two-dimensional thermodynamic diagram information; according to a corresponding relation between a preset pixel value range and a population activity density value, carrying out re-assignment on pixel values of pixels in the preprocessed two-dimensional thermodynamic diagram information to obtain initial reconstruction thermodynamic diagram information; checking the primary reconstruction thermodynamic diagram information to obtain secondary reconstruction thermodynamic diagram information; dividing the secondary reconstruction thermodynamic diagram information into a plurality of sub-regions according to a pres
