Method for measuring inclination angle of lens module

The invention discloses a method for measuring an inclination angle of a lens module, which comprises the following steps: providing a measuring device; providing a standard fixture which comprises a cylinder provided with a reflecting surface capable of reflecting laser; aligning the measuring device to the reflecting surface, emitting laser to the reflecting surface, and regulating relative positions of the standard fixture and the measuring device until a reflection angle of the laser is zero; fixing the lens module onto the standard fixture and making the reflecting surface positioned on aplane reserved for mounting an image sensor in the lens module; providing a horizontal reflecting mirror, and placing the horizontal reflecting mirror on an end face of one end of a lens barrel of the lens module, wherein the end is far away from the standard fixture; emitting the laser to the reflecting mirror to measure the reflection angle of the laser; and calculating the inclination angle ofthe lens module relative
