Abstract

The invention discloses a steel bar detection method based on a deep convolutional neural network, comprising steps: 1) data acquisition; 2) data processing; 3) model construction and training; 4) model evaluation; 5) model deployment. The present invention applies a target detection algorithm based on a deep convolutional neural network to steel bar detection and counting, and proposes a multi-scale and deformation-tolerant steel bar detection network framework. The framework integrates cascaded R-CNN with better detection performance, feature pyramid network that can effectively solve multi-scale detection problems, more stable group normalization, and deformable convolution that can improve the network's ability to learn spatial geometric deformation, etc. module. Compared with traditional steel bar detection methods, the network framework has higher detection accuracy and better generalization, and can be deployed on remote servers or mobile devices.

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...
