A method, system, self-moving robot, and/or readable storage medium can be used to generate a virtual boundary of a working region for a self-moving robot. A mobile positioning module circles for a predetermined number of loops along a patrol path formed by the boundary of the working region to acquire recording points which are stored and then retrieved in groups to acquire boundary fitting points forming a boundary fitting point sequence, from which boundary points are acquired. Successively connecting the boundary points generates the virtual boundary of the working region.
