The application provides a kind of drawing feature and digital matching method,
system, equipment and medium, comprising: obtaining three-dimensional model and automatically extracting all
relevant feature information;Obtain two-dimensional drawing and automatically extract all
label information;Overall projection is carried out to three-dimensional model, and the
model transformation projection image and projection information corresponding to three-dimensional model are generated;The
model transformation projection image and two-dimensional drawing are carried out hash calculation, and the section projection picture position of the three-dimensional model corresponding to two-dimensional drawing is found;According to feature information,
label information, two-dimensional drawing and step S3, determine three-dimensional model
projection image and projection information, determine which part of feature of three-dimensional model corresponding to
label information, and correspond label information to three-dimensional feature
list;Output labeled three-dimensional model and feature label data details.The application can improve the efficiency and accuracy of two-dimensional drawing information recognition in production and
processing, solve the problem of feature label information that two-dimensional drawing cannot be automatically recognized in automobile production.
