Abstract
A sectional image recognition method and a zonal recognition device are applied in a zonal fingerprint recognition device with small storage capacity. The method includes setting an image selection frame; capturing a corresponding fingerprint image block according to the image selection frame; executing a minutiae conversion program on the fingerprint image block to generate a minutiae block image corresponding to the fingerprint image block; repeating the foregoing steps until minutiae block image corresponding to all fingerprint image blocks are obtained; then executing an image stitching program on the corresponding minutiae block images according to acquisition sequence of the fingerprint image blocks for generating a minutiae image corresponding to the fingerprint image; executing a fingerprint recognition program on the minutiae image; and according to a recognition result acquired by the fingerprint recognition program, sending, by a zonal fingerprint recognition device, a corresponding response message to inform users of the recognition result.
