The application discloses a picture motion compensation method and
system in multi-screen combination and a storage medium, and relates to the field of picture display. The method comprises the following steps: acquiring first picture information and second picture information of different screen blocks respectively; determining distance direction offset and direction offset of picture pixel values of the first picture information and the second picture information based on a cross-correlation
algorithm; correcting the distance direction offset and the direction offset until absolute values of the distance direction offset and the direction offset are within a preset threshold; calculating picture display frequencies of the first picture information and the second picture information, adjusting time of a target splicing boundary of the first picture information and the second picture information based on the picture display frequencies; and multiplying a correction result of the distance direction offset and the direction offset and a time adjustment result of the target splicing boundary to obtain an offset compensation amount, and realizing picture motion compensation in multi-screen combination by using the offset compensation amount. The application better solves the problem of misalignment at a screen splicing position.
