Research on frosting detection method of air source Heat pump based on vision Technology

Abstract The outdoor pipe coil frosting of air source heat pump seriously affects the working efficiency equipment. Therefore, a new frost detection algorithm is proposed to optimize defrosting process. First all, image difference introduced remove interference factors in image. Then, brightness correction and denoising are carried out. Finally, combined with processing algorithms such as contour Otsu multi-threshold segmentation achieve regional detection, accuracy further improved. experimental results show that, compared existing methods, not only improves but also has better treatment effect on light changes frost. added Experimental that intelligent than current strategies.
