(57) Abstract: Image recognition method and apparatus, and computer-readable storage medium are provided. The method includes: 
determining changed object according to change of states of at least one group of target objects in detection area; obtaining a set of 
image frames in side view consisting of image frames in side view and at least one image frame to be matched that are collected within 
a first preset time period before states of at least one group of target objects in detection area are changed; determining associated image 
frame from at least one image frame to be matched; obtaining image frame in side view corresponding to associated image frame from 
the set of image frame in side view; and determining, according to associated image frame and image frame in the side view, target 
intervention object having the highest degree of association with changed object from at least one intervention object.
