MOTION ESTIMATION METHOD AND DEVICE, ELECTRONIC APPARATUS AND COMPUTER READABLE STORAGE MEDIUM

A motion estimation method and device, an electronic apparatus and a computer readable storage medium. The method comprises: acquiring image information of a frame where a current prediction unit is located, performing advanced motion vector prediction by using the image information to obtain a first initial motion vector, determining a motion vector having a minimum rate distortion cost, among the first initial motion vector and motion vectors of adjacent layer coding blocks of the coding block where the prediction unit is located, as a second initial motion vector, and performing pixel search on the basis of the second initial motion vector to obtain a target matching block. By applying the embodiments of the present application, a second initial motion vector having a smaller rate distortion cost can be obtained, a target matching block that is a closer match to the prediction unit can be obtained by using the second initial motion vector to perform pixel search, thereby improving the accuracy of the match
