The invention provides a parking space state detection method and system. The method comprises the steps of: judging whether a vortex light beam sent by an emission subsystem is received or not, wherein the topological charge value of the vortex light beam corresponds to the number of the parking space; if the vortex light beam is received, detecting a topological charge value of the vortex lightbeam; and determining that a target parking space is in an idle state according to the topological charge value of the vortex beam, wherein the number of the target parking space is the topological charge value of the vortex beam. According to the parking space state detection method and system provided by the invention, the vortex light beam is used for detecting the state of the parking space, external interference can be avoided, and the accuracy of a detection result is improved.
