Be 0 degree, the line in characteristic point and the center of circle clockwise to the angle folded by datum line as second feature;
In formula, EiRepresent the second feature of ith feature point, EiSpan be 0 to 360 degree, (xi,yi) represent i-th
The coordinate of individual characteristic point;
(2) using the fisrt feature of characteristic point as abscissa, second feature, as vertical coordinate, constructs coordinate system, by described
Palm vein and palmmprint main line bifurcation project in coordinate system, and the two-dimensional feature vector setting up pretreated palm image is empty
Between.
This preferred embodiment selects palm vein and palmmprint main line bifurcation as each spy of palm characteristics of image to be identified
Levy a little, both considered the memory space of iris identification device 1 and the restriction of the speed of service, reflect again palm vein and palmmprint
Change, the palm characteristics of image degree of accuracy to be identified of extraction is high, and extraction rate is fast.
Preferably, described palm characteristics of image identification module 25 is by described palm characteristics of image to be identified and image password number
When contrasting according to the palm characteristics of image as image password in storehouse 21, by the two dimensional character of palm characteristics of image to be identified
Vector space and the described distribution as the characteristic point in the two-dimensional feature vector space in the palm characteristics of image of image password
Carry out similarity comparison, particularly as follows: set the characteristic point in the two-dimensional feature vector space contrasting palm characteristics of image to be identified as treating
Identifying characteristic point, described is standard as the characteristic point in the two-dimensional feature vector space in the palm characteristics of image of image password
Characteristic point, carries out overlapping by palm image to be identified with the palm image in image password data base 21, and described as figure
The standard feature point corresponding to characteristic point to be identified is determined in the two-dimensional feature vector space in the palm characteristics of image of password,
Judge that characteristic point to be identified is less than predeterminable range threshold value and true according to judged result with the distance of corresponding standard feature point
Fixed palm characteristics of image to be identified is the most consistent with the described palm characteristics of image as image password.
This preferred embodiment sets palm characteristics of image identification module 25 and is identified palm characteristics of image to be identified
Time concrete operations, practical convenient.
This application scene Dynamic gene γ value to setting is as 1.02, and the accuracy of identification of central air conditioner system improves relatively
5.2%, recognition speed improves 7% relatively.
Last it should be noted that, above example is only in order to illustrate technical scheme, rather than the present invention is protected
Protecting the restriction of scope, although having made to explain to the present invention with reference to preferred embodiment, those of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention
Matter and scope.
