摘要： The present application relates to the technical field of 3D. Disclosed is a method for realizing 3D display, comprising: acquiring an image having eye space information of a user; acquiring eye positions of the user according to the image having the eye space information of the user and by means of a displacement sensor that operates independently relative to a main control chip of a 3D display terminal; and generating 3D display content according to a to-be-displayed image and the eye positions of the user. According to the present application, the displacement sensor that operates independently relative to a main control chip of a 3D display terminal is used to directly process the acquired image having eye space information of a user, instead of processing the image by means of the main control chip of the 3D display terminal, so as to avoid occupancy of a large amount of resources of the main control chip caused by processing the image having the eye space information of the user, so that dependence on the main control chip is reduced, and the timeliness of image processing is improved.
