The invention provides a railway ticket character region segmentation method and device, and the method comprises the steps of obtaining an initial image which comprises a railway ticket image; detecting a two-dimensional code area of the train ticket in the initial image; segmenting an image containing a target character object from the initial image as a first image based on the relative position relationship between the two-dimensional code area of the train ticket and the target character object; and detecting a boundary frame of the character area in the first image, and segmenting the image contained in the boundary frame in the first image as a target image. According to the method and the device, the character region segmentation accuracy can be improved.
