The invention discloses a space distribution method used for a space variable cabinet and based on binocular measurement for article volume recognition, and the method comprises the steps: S1, carrying out the photographing of an article through employing a binocular measurement system, and obtaining a corresponding image; S2, calculating a characteristic value, searching an area which is most matched with the characteristic value, and calculating the parallax of each point; S3, calculating the depth of field through parallax, and calculating the actual size of the article through the global depth of field; S4, determining the required size T of the virtual cell according to the actual size; and S5, allocating an optimal space to the article. The method has the advantages of being simple in principle, easy to implement, and capable of achieving space variable optimal configuration and the like.
