Hand shape recognition device based on sparse representation and hand shape recognition method thereof

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. The controller is coupled with the input device, the output device, the display screen and the power supply module. The hand shape recognition device is characterized in that the input device is used for acquiring the hand shape features of a user and converting the hand shape features into standard signals to be outputted to the controller. The controller is provided with a built-in database and performs data comparison with the data in the built-in database according to the received standard signals and outputs the comparison result through the output device and the display screen. The power supply module supplies DC voltage to the controller. The hand shape recognition device is easy to productize and miniaturize and has high recognition rate and anti-counterfeiting degree in recognition operation. 本发明涉及种手形识别装置，包括输入装置、控制器、输出装置、显示屏和电源模块，其中控制器分别耦接输入装
