The perception and interpretation of the surrounding space is essential for human life, which
is the basic ability of human survival and reproduction. Based on previous studies, human beings can
accurately locate themselves and other objects in the environment with abundant clues. The theoretical
and Experimental Research on the mechanism of this localization has always been a hot topic for
psychologists. The ground theory of space perception is a frontier theory about the interpretation
of human distance perception. Based on this theory, researchers have carried out a large number of
experiments. In this paper, the background, main content and theoretical extension of the ground theory
are introduced,and this paper also point out the possible research direction in the future.
