Embodiment

[0039] Such as figure 1 , figure 2 , image 3 Shown, the present invention is a kind of method of the comparison analysis similarity of a kind of broken line, and it comprises initial A coordinate storage module, initial B coordinate storage module, merged coordinate module, computing module, and it comprises the steps:

[0040]1. The coordinates of the broken line LineA are stored in the initial A coordinate storage module, and the coordinates of the broken line LineB are stored in the initial B coordinate storage module. AXmin and BXmin are the minimum values ​​of the X-axis interval of LineA and the X-axis interval of LineB respectively, and AXmax and BXma x is the maximum value of the X-axis interval of LineA and the X-axis interval of LineB, input the X-axis interval of LineA and the X-axis interval of LineB into the combined coordinate module, and obtain the X-axis merged interval [Xmin, Xmax], where Xmin is AXmin, the minimum value of BXmin, where Xmax is the maximum...

Abstract

The invention relates to a method for comparatively analyzing similarities of fold lines. Deviation and coupling degrees are indicated through quantitative indexes, and the similarities of a plurality of fold lines can be compared through the quantitative indexes. The method is mainly characterized in that direct deviation and square deviation can be accumulated through summarized fold lines obtained by sectional summarizing for X axes of the fold lines and are compared with reference values of direct deviation and square deviation to obtain percent quantitative indexes, so that the similarities of the fold lines are indicated through the quantitative indexes.

Description

technical field [0001] The invention relates to a computer software, in particular to a method for comparing the similarity of two polylines in the computer software. Background technique [0002] In some data mining and analysis processes, it is necessary to analyze the plane coordinate points composed of some discrete data, so as to obtain the relationship between these plane coordinate points. If the plane coordinate points formed by two sets of data in a sequential relationship form two polylines with a sequential relationship, it is also important and effective to analyze the similarity of the two polylines by computer. A step of. However, in the existing software, the judgment of the similarity between two polylines is very rough, and its reliability is not high. Contents of the invention [0003] The present invention mainly solves the technical problem that judging the similarity of two broken lines is very rough and the reliability is not high in the prior art, ...
