The present invention discloses a character area location method and device in an image. The method comprises: constructing a parameter regression model; generating a text space distribution parameter corresponding to an image through the parameter regression model; and reconstructing a character-non-character binary image corresponding to the image according to the text space distribution parameter. The embodiment of the invention further discloses a character area location device in an image. Compared to the prior art, according to the technical scheme of the embodiment, a traditional mode of character area location through the image contour or area features is completely abandoned, and the character area location method and device in an image perform analysis and location of the character area through the deeper hierarchy meaning characteristic and the image text space distribution parameter to avoid the interference of the size, the character font, the color and the language of the image on location so as to have more accurate location and better robustness; and moreover, the method provided by the invention can be applied to various types of images based on the most basic meaning characteristic of the image and has versatility.
