Abstract

The invention discloses a target object image acquisition guiding method and system. The method comprises the steps of obtaining a region of interest of a to-be-detected target object image; accordingto a preset image recognition algorithm, comparing the region of interest of the to-be-detected target object image with a guide map calibrated by an image library to generate a comparison result; and generating position movement guide information based on a comparison result, and displaying the position movement guide information through voice and / or characters to guide a user to complete imageacquisition of the to-be-detected target object. A hardware guiding device is replaced by software, so that a user can be conveniently, quickly and intelligently guided to acquire an image of a targetregion of interest.
