Abstract

The invention discloses a steel bar detection method based on a deep convolutional neural network. The method comprises the following steps: 1) data acquisition; 2) data processing; 3) constructing and training of a model; 4) model evaluation; 5) model deployment. The target detection algorithm based on the deep convolutional neural network is applied to reinforcing steel bar detection and counting, and a multi-scale and deformation-tolerant reinforcing steel bar detection network framework is provided. Cascade R-CNN with good detection performance, a feature pyramid network capable of effectively solving the multi-scale detection problem, a more stable group normalization module, and a deformable convolution module capable of improving the spatial geometric deformation capacity of network learning and other modules are integrated in the frame. Compared with a traditional steel bar detection method, the network framework is higher in detection precision and better in generalization, and can be deployed in a remote server or a mobile device.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a steel bar detection method based on a deep convolutional neural network. Background technique [0002] Object detection is one of the basic problems in the field of computer vision, and its task is to determine the category, size and location of objects in a given image. As one of the cores of computer vision and image semantic understanding, the development of object detection will help to achieve more complex and higher-level vision tasks, such as semantic segmentation, scene understanding, object tracking, and action recognition. For this reason, target detection has always been an active research field in computer vision, and has extremely high academic research value and industrial application value. [0003] In recent years, with the rapid development of deep learning and the continuous improvement of hardware computing capabilities, convolutional neura...
