Abstract
An intra prediction method and device and a computer storage medium are provided. The intra prediction method includes that: a width-to-height radio of a present coding block and a width-to-height radio of a reference block are acquired, the reference block being a coding block correlated with the present coding block (S); when the width-to-height radio of the present coding block is different from the width-to-height radio of the reference block, an angular replacement prediction mode corresponding to the reference block is adjusted to obtain a adjusted angular replacement prediction mode, the angular replacement prediction mode being an extended angular prediction mode under a wide-angle mode (S); and a prediction mode list of the present coding block is constructed based on the adjusted angular replacement prediction mode for intra prediction of the present coding block (S).
