The invention belongs to the field of laser projection display and relates to a vibrating mirror-based laser projection display method and specifically relates to a vibrating mirror-based spiral scanning laser projection method and system. A vibrating mirror is enabled to perform resonance oscillation around two axes, a scanning trajectory is spirally scanned, and the scanning trajectory is used to realize projection. The vibrating mirror-based spiral scanning laser projection method and system can be used for solving problems of complex algorithms, low projection resolution, excessively low resonant frequency of the vibrating mirror, low vibration resistance vibration resistance and the like of conventional MEMS vibrating mirror-based laser projection display which is performed via a Lissajous Scanning and grating scanning method.
