Example Embodiment

[0055]In order to make the objects, technical solutions, and advantages of the present application, the technical solutions in the present application embodiment will be described in connext of the present application embodiment, and It is a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative labor are the scope of the present application.

[0056] In practice, it is found that different components are different in the number of architectures, resulting in imbalance of training data samples, and the number of different components present long-tail distribution, especially those with high frequency, very small, so that identification The model cannot be well trained, the recognition accuracy is low.

[0057] In view of the above technical problems found in the actual work, the present application provides a met...

Abstract

The invention relates to a component identification method and device, a training set construction method and device, equipment and a storage medium, and the method for constructing a training set comprises the steps of determining that a target component exists in a first architectural drawing; performing data enhancement on the first architectural drawings to obtain a drawing set of the first architectural drawings; for each drawing of the drawing set, selecting at least two different initial positions on the drawing, and segmenting the drawing according to the initial positions to obtain a plurality of sub-graphs; obtaining a target sub-graph containing the target component from the plurality of sub-graphs, wherein the target sub-graph is used for constructing a training set of the target component. The invention is used for solving the problem of poor recognition effect of a recognition model caused by limited sample quantity in an intelligent drawing auditing process.

Description

technical field [0001] The present application relates to the field of intelligent drawing review, in particular to a method, device, equipment and storage medium for constructing a training set and a method for component recognition. Background technique [0002] Along with the rapid development of the economy, the construction industry has also been vigorously developed. Architectural drawings are an important basis for construction. There are many components in architectural drawings, and the design of each component should comply with the corresponding national norms and industry standards. Qualified architectural drawings are crucial to ensuring the safety of residents. [0003] Identifying components is an important part of automatic review of architectural drawings. Currently, neural networks, such as convolutional neural CNNs, can be used to identify and locate building components. However, when the neural network recognizes the target, it needs to use a large numb...
