The present invention relates to an all-around spherical light field rendering method, comprising: a preparation step, i.e., preparing to input and load related files; pre-computing a latticed depth map of positions of reference cameras which are densely covered on a sphere; moving a rendering camera, enabling the moving range of the rendering camera to be the surface of the sphere, and calculating and identifying the reference cameras surrounding the rendering camera around the rendering camera; performing back projection on pixels of the rendering camera, and performing depth test with the four reference cameras; and interpolating the reference cameras passing through the depth test, thereby obtaining a finally rendered pixel value. By means of the present invention, the rendering results can be rapidly seen in real time; an object can be observed from any angle on the spherical surface, and a real immersion feeling can be felt.
