Abstract

The invention discloses a method for turning off a palm image recognition device. The method comprises the following steps: comparing an obtained current image in an image acquisition area with a previous image; if similarity between the current image and the previous image is lower than a preset first index, turning off a light supplement lamp; detecting whether the image acquisition area has an object through probe light; and if the image acquisition area has no object, turning off the palm image recognition device. The technical problem that the palm image recognition device is turned off by mistake or an image sensor keeps collecting palm images since it is difficult to determine whether a palm quits the image acquisition area under joint influence of the light supplement lamp and stronger ambient light is solved.

Description

technical field [0001] The invention relates to the technical field of biometric identification, in particular to a method and device for closing a palm image recognition device. Background technique [0002] Biometrics technology is to use the inherent physiological characteristics of the human body (such as fingerprints, faces, irises, etc.) and behavioral characteristics (such as handwriting, voice, gait, etc.) for personal identification. In the field of biometric technology, the application of palm recognition is more and more extensive. Usually, palm recognition uses near-infrared LED lights for supplementary light, and obtains the image of the palm through the image sensor (CMOSSensor), and then transmits it to the back-end processor for processing and recognition comparison. [0003] When the palm image recognition device is working, the supplementary light is always turned on to maintain the supplementary light state, and at the same time, the image sensor continu...
