Title
(EN) METHOD FOR COMPARING FITTINGNESS OF TWO-DIMENSIONAL DRAWING IN ENGINEERING
(FR) PROCÉDÉ DE COMPARAISON DE LA CONFORMITÉ D'UN DESSIN BIDIMENSIONNEL DANS L'INGÉNIERIE
(ZH) 用于工程中的二维图吻合度比对的方法
Abstract
(EN)
A method for comparing the fittingness of a two-dimensional drawing in engineering, at least comprising the following steps: A. obtaining vector and bitmap information of a standard drawing which serves as a foundation and of a project drawing; B. carrying out hash operation on entity types and characteristic points in the vector and bitmap information, and comparing project information of the same hash value; C. calculating at least one or more pieces of information out of an entity change percentage, an area difference percentage, a manual intervention area change percentage and a pixel difference percentage according to the comparison result; and D. obtaining drawing fittingness information according to the obtained information and difference entity weight information. The described method only compares the same parts of a project drawing and a standard drawing, that is, the ratio of an entity in the project drawing that is the same as that in the standard drawing multiplied by a corresponding layer weight value to the total entity in the standard drawing multiplied by a corresponding layer weight, thus ensuring a good fit between the comparison result and a comparison made by a person.

L'invention concerne un procédé de comparaison de la conformité d'un dessin bidimensionnel dans l'ingénierie, comprenant au moins les étapes suivantes : A. obtention d'informations vectorielles et matricielles d'un dessin standard qui sert de base et d'un dessin de projet ; B. réalisation d'une opération de hachage sur des types d'entités et des points caractéristiques dans les informations vectorielles et matricielles et comparaison des informations de projet ayant la même valeur de hachage ; C. calcul d'au moins un ou plusieurs éléments d'informations parmi un pourcentage de changement d'entité, un pourcentage de différence de zone, un pourcentage de changement de zone d'intervention manuelle et un pourcentage de différence de pixel en fonction du résultat de la comparaison ; et D. obtention d'informations de conformité de dessin en fonction des informations obtenues et des informations de poids d'entité de différence. Le procédé décrit compare uniquement les mêmes parties d'un dessin de projet et d'un dessin standard, à savoir le rapport entre une entité dans le dessin de projet, qui est la même que celle dans le dessin standard multipliée par une valeur de poids de couche correspondante, et l'entité totale dans le dessin standard multipliée par un poids de couche correspondant, ce qui garantit une bonne conformité entre le résultat de la comparaison et une comparaison effectuée par une personne.

一种用于工程中二维图吻合度对比方法,至少包括以下步骤:A、获取作为基础的标准图以及项目图的矢量以及位图信息;B、将矢量以及位图信息中的实体类型以及特征点进行哈希运算,比较同一哈希值的项目信息;C、根据比较结果计算至少获得实体变化百分比,面积差异百分比,人工干预面积变化百分比,像素差异百分比中的一个或多个信息;D、根据上述获得的信息以及差异实体权重信息获得图纸吻合度信息。所述方法只比较项目版图纸与标准版图纸中相同部分,即项目图中与标准图中相同的实体乘以相应的图层权重值与标准图中的总实体乘以相应图层权重的比值,这样就保证了比对结果与人为比对的高吻合度性。
