Abstract
Disclosed are a method and device for generating a predicted picture, the method comprising: determining a reference rectangular block of pixels according to parameter information which includes a location of a target rectangular block of pixels and/or depth information of a reference view; mapping the reference rectangular block of pixels to a target view according to the depth information of the reference view to obtain a projection rectangular block of pixels; and acquiring a predicted picture block from the projection rectangular block of pixels. The technical problem of relatively large dependence among the data brought by simultaneously employing the depth picture of the target view and the depth picture of the reference view in the process of generating the predicted picture in the prior art is solved, and the technical effects of reducing the dependence on the data and improving the encoding and decoding efficiency is achieved.
