Abstract
Provided are a method, apparatus and device for detecting a field curvature of a VR optical module, wherein a diaphragm is fixed on a lens of a camera, a first electronic control is used to drive the VR optical module to self-rotate around an optical axis of a VR lens, and a second electronic control is used to drive the camera to swing in a plane where the optical axis of the VR lens is located with a center of the diaphragm as a fixed point.
