The invention relates to a hand shape recognition device, comprising an input device, a controller, an output device, a display screen and a power supply module, wherein the controller is respectively coupled to the input device, the output device, the display screen and the power supply module, and is characterized in that: the input device The device is used to collect the user's hand shape characteristics and convert them into standard signals and output them to the controller. The controller has a built-in database, which compares data with the data in the built-in database according to the received standard signals, and passes the comparison results through the output device. and the display screen for output, and the power module provides DC voltage to the controller. The hand-shaped recognition device is easy to be productized and miniaturized, and has high recognition rate and anti-counterfeiting degree during operation.
Description
technical field [0001] The invention relates to a hand shape recognition device and method thereof, in particular to a hand shape recognition device and method based on sparse representation. Background technique [0002] At present, there are many personal identification technologies widely used, such as fingerprint recognition, iris recognition, face recognition and vein recognition technology, etc. CN205015896U discloses a biometric identification device, which can be compared and identified by biological bodies. CN105069337A discloses a screen unlocking method based on palm biometric information and a mobile device, which can identify biological objects based on biometric information such as palm prints or veins, etc., but these technologies have certain problems. Fingerprint identification technology is affected by environmental factors such as dust, oil, and water. Problems such as broken lines, no fingerprints, peeling and scars affect the quality of image acquisition...
