New Algorithm of Liquid Level of Infusion Bottle Based on Image Processing

The key of intelligent infusion system is to detect liquid level of infusion bottle fast and accurately. We proposed an automatic detection algorithm of liquid level of infusion bottle based on image processing, by designing edge detection, binarization, filtering, image projection and motion detection to realize automatic liquid level detection. The algorithm has the advantages of stable noise-resistance, rapidity and simplicity, etc. Experimental results of the algorithm show that the algorithm is effective and feasible.
