Abstract

The invention provides a corpse iris recognition method and device, and the method comprises the following steps: collecting a corpse iris image, and carrying out the iris image quality evaluation ofthe collected corpse iris image; performing first corpse iris quality evaluation on the corpse iris image; carrying out iris detection and positioning on the iris images with the image quality meetingthe preset quality standard; matching the corpse iris image data positioned in the iris area with iris data in a living iris database, and obtaining at least one matching result and a corresponding confidence coefficient; and comprehensively analyzing and outputting a final identification result based on the quality evaluation result, the matching result and the corresponding confidence. The embodiment of the invention provides an effective means for efficient high-precision corpse identity confirmation.

Description

technical field [0001] The invention relates to iris recognition technology, in particular to a dead body iris recognition method and device. Background technique [0002] Due to the high stability and uniqueness of the iris, it is regarded as a highly secure biometric feature, and is suitable for identification and authentication scenarios that require high precision. At present, iris recognition technology is used in public security criminal investigation, prison, suspect investigation, immigration and other living person identity management, and has accumulated a large number of iris image data of suspects and floating population. [0003] In the traditional autopsy identity confirmation, fingerprint comparison and identification, DNA comparison and identification, relevant person identification and other methods can be used to confirm the identity of the corpse. When encountering factors such as damaged or missing fingerprints and damaged facial features, you can only r...
