Dashboard is an important tool to support manufacturing enterprises in data visualization analysis and business decision-making.In order to solve the problems of users’ strong dependence on professional knowledge and complicated process iteration in the design and implementation of visual dashboards,a method for automatic recognition and generation of visual dashboards based on the YOLOv5s algorithm in deep learning technology is proposed.Firstly,based on the YOLOv5s algorithm,the visual chart components contained in the dashboard images and hand-drawn sketches are detected,and in order to address the problems of interference and false detection caused by irregular lines in hand-drawn sketches during the detection process,the CA attention mechanism is introduced to enhance the ability of the model to focus on important features and accurately locate the target,so as to improve the recognition accuracy of the model.Secondly,deploy the chart detection model in the web,and the server calls the encapsulated visual chart component code according to the model detection results to generate the initial dashboard of multi-component combination.Finally,a data visualization dashboard building platform is developed based on this web design,which provides users with detailed options to modify and configure the dashboard style and data,so that users can quickly build a complete dashboard.Through the collection of dashboard images generated by visualization tools such as Tableau and Power BI and hand-drawn dashboard sketches during the enterprise application process to form a dataset for experimental validation,the improved model increases the recognition accuracy by 2.1% compared to the original YOLOv5s model,and the mAP is 98.4%.The system deployment application verifies that the chart recognition method and the developed platform can effectively identify and generate the corresponding chart components to meet the basic needs of users.
