Automatic Acquisition of Pointer Instrument Readings Based on Intelligent Cameras
Pointer instruments are widely used in traditional industries,and how to automatically obtain their readings is an urgent problem in the current industrial production field.An automatic reading acquisition algorithm based on intelligent camera is designed.After collecting the image of the instrument dial,binary pre processing is performed,and the position of the pointer is extracted using mathematical morphological analysis and Hough trans-form.The angle of the pointer on the dial scale is calculated,and the accurate reading of the pointer is finally ob-tained.The experimental results show that the algorithm can obtain the instrument reading stably and reliably,and the recognition accuracy meets the industrial requirements.
