Intelligent palm shape recognition instrument

Abstract

The invention relates to an intelligent palm shape recognition instrument, and the recognition instrument is convenient for standard placement and bacterial infection prevention. The recognition instrument comprises a detection box, a support plate, and a display box. A translation mechanism, a positioning mechanism, a cleaning mechanism and a placement mechanism are disposed between the detectionbox and the display box. The placement mechanism comprises a first motor, drive wheels, drive teeth, and a glass plate. The positioning mechanism comprises a moving plate, a positioning plate, two lifting assemblies, and four positioning components. The cleaning mechanism comprises a moving block, a connecting block, a frame, and a cleaning block. The recognition instrument enables the posture ofa palm to be standard through the positioning mechanism, facilitates the accurate recognition, and improves the judgment efficiency and precision of equipment. Moreover, after identity recognition, the glass plate is driven by the first motor to rotate, and is cleaned through the cleaning mechanism, thereby preventing the bacteria on the glass plate from spreading to the palms of other users, andimproving the practicality of the equipment.

Description

technical field [0001] The invention relates to the field of biometric identification equipment, in particular to an intelligent hand-shaped identification instrument for preventing bacterial infection that is convenient for standard placement. Background technique [0002] Palm recognition is a biometric technology that uses the shape of the palm, the length of the fingers, the width and thickness of the palm, and the width and height of the two joints of each finger as characteristics. This feature of the human body is stable within a certain period of time. , such as a sports meeting or an active device, the feature reading device collects it, and forms the comprehensive data (feature value) of the feature, and then compares it with the user template stored in the database to determine the identity of the recognition object. At present, palm shape recognition technology is developing rapidly, mainly using infrared plus camera to capture the complete opening shape of the h...

Problems solved by technology

[0003] However, the existing palm shape recognition is the same as fingerprint recognition, which requires human contact with the reading device during operation. With the increase of the number of people to be recognized, the bacteria in the palm residue will be spread on the recognition device, and the bacteria will be transmitted to other personnel through contact. hands, resulting in unhygienic use of the existing palm-shaped recognition device, not only that, the use of the palm-shaped recognition device needs to place the palm in a standardized manner, so certain learning must be done when using the recognition device, and in the process of use, it takes about It takes 15 seconds to make a person place the palm correctly and standardizedly to ensure that the device can correctly identify the palm. Therefore, the recognition accuracy and recognition efficiency of the existing palm shape recognition devices are very low.
