Research on Instrument Position Detection Method Based on YOLOV4

With the advent of the era of Industry 4.0, more and more industrial production sites have introduced information technology and intelligent technology. Identification of indicator number in pointer instrument is one of the important applications of intelligent industry, and the instrument positioning is the first premise to realize the indicator number reading of pointer instrument. Accurate position detection in the image can provide a solid foundation for the correct reading of indicator number. This chapter focuses on the research of instrument position detection methods. Firstly, the basic theory of target detection technology is summarized. Secondly, the YOLOV4 target detection technology is introduced, and the improvement is proposed based on specific industrial scenarios. Finally, a simulation experiment is conducted to verify the effectiveness of the improved method proposed in this chapter.
