Description
Technical field:
The present invention relates to a kind of electric motor car charging plugboard adopting personal recognition technology, belong to household electrical appliance technical field.
Background technology:
Personal recognition is a kind of newer biometrics identification technology proposed in recent years.Palmmprint refers to the palm image of finger tips to wrist.Wherein a lot of feature can be used for carrying out identification: as main line, wrinkle, tiny texture, ridge tip, bifurcation etc.Personal recognition is also a kind of non-offensive recognition methods, and user is more acceptant, less demanding to collecting device.In palmmprint, most important feature is streakline feature, and in these streakline features the most a few streak line be with not changing throughout one's life of people substantially.And still can recognize clearly in low resolution and low-quality image.Point patterns mainly refers to the skin surface feature similar with palmmprint that palm has, if palmmprint mastoid process line is the singular point be partially formed and line shape.Point patterns needs to obtain in high-resolution and high-quality image, therefore higher to the quality requirement of image.Textural characteristics, mainly refers to some shorter than streakline, thinner streaklines, but its distribute on palm be milli irregular.The feature of palmmprint also comprises geometric properties: as the width of palm, length and geometry, and the distribution of palm zones of different.The abundant information that the information comprised in palmmprint comprises more than one piece of palmmprint, utilizes the streakline feature of palmmprint, point patterns, textural characteristics, geometric properties can determine the identity of a people completely.Therefore, theoretically, palmmprint has the distinguishing ability than the better resolution capability of palmmprint and Geng Gao.
Similar to palmmprint, also containing crestal line and minutiae point on palmprint image.Funada J proposes a kind of method that fold by eliminating palmmprint extracts mastoid process line, but this method is only limitted to the crestal line extracting palmprint image, is not used successfully to personal recognition.Duta proposes a kind of palm grain identification method based on palmprint image characteristic point.Chen etc. attempt the buckle point estimating palmmprint by producing local gray level field of direction image, and the form forming straightway that coupled together by these points is used for follow-up coupling.Streakline on palm is feature the most intuitively, and a lot of document all have studied the line features of palmmprint, extract streakline feature be actually low contrast, strong noise background condition under rim detection.Document employs the line features of palmmprint the earliest for personal recognition, and this method only extracts the short lines on palm.The people such as Han then adopt morphology and Sobel edge feature to describe palmmprint, and train a neural network classifier for checking.Based on the pyramid edge detection algorithm of Stack Filtering be also used to extract palmmprint line features according to the operator of the concept structures such as the burn into expansion in gray scale morphology.Recognizer based on point, line features is the most direct method in personal recognition.Point patterns can describe palmprint image accurately, and robustness is comparatively strong, distinguishing ability is high.But point patterns needs to extract in high-resolution image.If the quantity of point is more, then need a large amount of calculating consumption during coupling.Line features is obviously stablized, and method for expressing is simple, and feature space is little.But point patterns and line features cannot represent the depth and the dynamics of palmmprint streakline, and larger by the interference of noise.
