P&ID (Piping and Instrumentation Diagram) is a typical diagram used in the process plant industry. Intelligent P&ID has the advantage of being able to automate searches and queries and keeping the latest information. With these advantages, the demand for intelligent P&ID continuously increase in the field. However, there is a large amount of image-type P&ID that was produced before the intelligent P&ID became common. Therefore, a technology that automatically converts image-type P&ID into intelligent P&ID is required. In this research, we propose a method to recognize the main objects in image format P&IDs using deep learning and image processing techniques. The main recognition targets are symbols, character strings, lines, and tables in P&ID. Finally, the proposed method was verified through the implementation of a prototype system and experiments with a sample P&ID.
