Power grid engineering contract evaluation method based on image processing

Abstract

The invention relates to a power grid engineering contract evaluation method based on image processing. The method comprises the following steps: S1, obtaining an image of a power grid engineering contract, and carrying out the preprocessing; s2, extracting a special clause part in the power grid engineering contract image, and converting the special clause part into a word format; s3, acquiring aspecial clause part corresponding to the standard electronic contract; s4, searching the same special term from the paper contract image and the standard electronic contract according to the searching and positioning conditions, and calculating the text similarity between the paper contract image and the standard electronic contract; s5, repeating the step S4 until text similarity calculation ofall special terms is completed; s6, according to the text similarity obtained through calculation, contract similarity is obtained through calculation, if the contract similarity is higher than a setthreshold value, the contract evaluation result is qualified, otherwise, the contract evaluation result is unqualified, and compared with the prior art, the method has the advantages that the contractevaluation efficiency is improved, and intelligent contract evaluation is achieved.

Description

technical field [0001] The invention relates to the field of contract intelligent evaluation, in particular to an image processing-based power grid engineering contract evaluation method. Background technique [0002] Power grid construction is in a stage of rapid development. my country’s power grid construction investment is increasing year by year. However, due to the long cycle of technical and economic management work, many repetitive tasks, and high risk of post-event management, in order to achieve lean cost control, it is urgent to improve technical and economic management information. to build a “big data” system for technical and economic management of power grid engineering. [0003] Among them, contract management is an important part of process management in technical and economic management. At present, the contract is usually evaluated by means of manual checking, which often takes a long time, affects the construction period and increases the project cost. T...

Problems solved by technology

However, at present, there is still insufficient research on how to intelligently evaluate contract terms through digital and intelligent technologies, which cannot meet the requirements for intelligent evaluation of power grid engineering contracts.
