Method and system for personal identification using 3d palmprint imaging

A method for identifying a person using their palm, the method comprising:

• capturing a three-dimensional (3D) image of the palm of the person;
• extracting a 3D subimage from the captured image;
• and
• extracting 3D palmprint features from the 3D subimage;
• wherein the extracted 3D palmprint features are compared to reference 3D palmprint features to verify the identity of the person.

An image acquisition device for identifying a person using their palm comprising:

• a light emitting device to project stripe patterns onto the surface of the palm for obtaining depth information using active triangulation;
• an image capture device to captures a three-dimensional (3D) image of the palm;
• an image processing module to process the captured image by:
• extracting a 3D subimage from the captured image;
• extracting 3D palmprint features from the 3D subimage;
• and
• comparing the extracted 3D palmprint features to reference 3D palmprint features to verify the identity of the person.
