Claim 6:
7. The text recognition method according to claim 1, wherein the correcting the polygonal area to m−1 rectangular areas comprises:
dividing the polygonal area into m−1 quadrilateral areas that do not overlap each other, wherein any quadrilateral area is obtained based on two adjacent vertex pairs in the m vertex pairs,
the two vertices included in each of the m vertex pairs are located on two sides of the center line of the target text detection area, and a midpoint of a connection line between the two vertices in the vertex pair is located on the center line; and
respectively correcting the m−1 quadrilateral areas that do not overlap each other to the m−1 rectangular areas.
