Multi-modal biological recognition system and method based on holographic projection interactive mode

Abstract

The invention discloses a multi-modal biological recognition system based on a holographic projection interactive mode. The system comprises a processing unit and a power supply module electrically connected with the processing unit, wherein the processing unit is electrically connected with a scene camera group, a biological recognition camera group, an LED (light emitting diode) light source group, a recognition unit, a holographic projection unit and a communication module. The system has the beneficial effects that a user can perform man-machine interaction through limb actions; various biological information recognition methods are provided; the science and technology feeling is dye-in-the-wood; the man-machine interaction mode is very friendly.

Description

technical field [0001] The present invention relates to the technical field of biological identification, in particular to a multi-modal biological identification system and method based on a holographic projection interaction mode. Background technique [0002] At present, there are more and more applications of biometric identification technology. Face recognition technology, fingerprint recognition technology, etc. have been widely accepted by the general public. In addition, iris recognition technology, vein recognition technology, gait recognition technology, palmprint recognition technology, etc. There are applications in special fields. I believe that with the development of science and technology, it will gradually reach the general public. [0003] The core technology of biometrics is to be able to determine the identity of a person and has biological vitality. In 2013, the Chinese citizen ID card has collected the fingerprint information of citizens. It is believed...

Problems solved by technology

Biometric technology is particularly important to the field of homeland security. Biometric devices will appear in entry-exit and important forbidden areas. However, the biggest shortcoming of current biometric technology identification devices is that the human-computer interaction method is not friendly, because many biometric information collection is non-contact. Collection, such as face and iris information, long-distance identification equipment, if the display screen is small, it cannot give users a good guide, if the display screen is large, it is not beautiful and violates user information, and general identification equipment has certain The recognition distance and range, too far or too close will not work, many users do not care about voice prompts and image display, especially in the case of biometric identification in other countries without knowing a foreign language, the equipment with poor usability will always put the user in an embarrassing situation
