The embodiment of the invention provides a scene description file analysis method and device, and relates to the technical field of video processing. Comprising the steps that a target touch action node array is acquired from an MPEG interaction description module of a scene description file of a to-be-rendered three-dimensional scene; determining an index value of a target tactile object description module corresponding to a tactile object associated with the target action node according to the target tactile action node array; obtaining the target touch object description module from the MPEG touch description module of the scene description file according to the index value of the target touch object description module; and obtaining description information of a tactile media accessor associated with the target action node when the to-be-rendered three-dimensional scene executes a target tactile action according to the target tactile object description module, wherein the target tactile action is a tactile
