Method, apparatus and system for information identification

摘要

Methods, apparatus, and systems for information identification are provided. A card image of a pre-set collection area is photographed and obtained, when a request event for information identification is detected. Edge-size information of the card image obtained by photographing is determined. A target area of the card image is marked according to the edge-size information. An image of the target area is extracted. Character shapes to be identified in the image of the target area is determined based on a pre-set character pattern library. A character corresponding to each character shape to be identified is identified according to each character shape to be identified that is determined and according to the character pattern library.
