Patent ID: 8700498

Claim:
A feature analysis apparatus where a plurality of categories expressing features of an inspected object defined by inspected object information in a predetermined format are set as a plurality of layers, a plurality of feature parameters belonging to each of the plurality of categories are set, and directions on the same plane are assigned to the plurality of respective feature parameters, having a camera unit for acquiring inspected object information of an inspected object under analysis, a parameter value determining program of a computer processing unit for analyzing the acquired inspected object information and determining values of feature parameters of each of the plurality of layers, a parameter vector generating program of the computer processing unit for generating a single parameter vector based on values of said plurality of feature parameters and corresponding directions for each of said plurality of layers, a vector converting program of the computer processing unit for converting the parameter vector obtained for each of the plurality of layers to a layer vector of a 3D vector in a predetermined 3D space, and a feature information generating program of the computer processing unit for generating a set of coordinate values in said 3D space of a plurality of nodes obtained by coupling a plurality of layer vectors obtained for said plurality of layers in the order of said layers as feature information expressing said features of the inspected object under analysis.
