The invention discloses laser resonant cavity automatic cavity adjusting system and method based on interference fringe picture skeleton line processing. The automatic cavity adjusting system comprises a guide light laser, a laser resonant cavity, a coupling output mirror, a camera, a computer and a cavity mirror control system, wherein the laser resonant cavity comprises an adjustable cavity mirror. The invention also provides an automatic cavity adjusting method corresponding to the automatic cavity adjusting system, which can perform rapid and precise judgment on the alignment of the laserresonant cavity and provide a control signal in real time for the cavity mirror control system, thereby achieving the aim of rapidly and automatically adjusting a cavity. By adopting the cavity adjusting system and the cavity adjusting method, the precision, speed and repeatability of the traditional manual cavity adjusting method can be effectively improved. In addition, the method can be further popularized and applied
