Abstract

The embodiment of the invention discloses a legend complexity sorting method and device, a legend matching method and device and computer equipment, and relates to the technical field of image processing, and the method comprises the steps: obtaining a parameter file corresponding to a legend standard library, wherein the parameter file corresponding to the legend standard library comprises at least two standard legends and primitive parameters corresponding to each standard legend; calculating a complexity coefficient corresponding to each standard legend according to the primitive parametersof all the primitives contained in each standard legend; and sorting all the standard legend in the legend standard library according to the complexity coefficients from large to small in sequence toobtain a standard legend complexity sequence. According to the technical scheme, the complex legend can be recognized in a targeted mode, the complex legend is effectively prevented from being mistakenly recognized, and therefore the recognition result is more accurate.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a legend complexity sorting method, legend matching method, device and computer equipment. Background technique [0002] In power design, when the computer analyzes and recognizes the power design drawings, it needs to match the multi-type standard legends contained in the standard library library with the possible legends in the drawings. In the process of matching and identifying possible legends with standard legends, there are situations where the basic primitives of some complex legends completely contain all the basic primitives in simple legends. In this case, complex legends are likely to be recognized as multiple simple legends, and complex legends cannot be identified in a targeted manner, so that the recognition results do not meet actual needs. [0003] Therefore, in order to avoid misidentification of complex legends, an optimized legend matching recognition method i...
