Embodiment Construction
[0053] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0054] An identification system such as figure 1 As shown, it includes near-infrared LED, CCD image sensor, FPGA and PC; wherein the output end of near-infrared LED is connected with the input end of CCD image sensor, the output end of CCD image sensor is connected with the input end of FPGA, and the output end of FPGA Connect to PC. Firstly, high-resolution palm vein images are collected through the image acquisition front-end combined with CCD image sensor and FPGA, and then the original palm vein images are preprocessed, and the training data (obtained during registration) and test data (online verification) are extracted respectively. The local invariant features of the image, and use the Euclidean distance to measure the similarity between the test data feature poi...
