Recognition of Flow Readings for Float Flowmeters Based on Digital Image Technique

Xiao-xuan Cao, Yu-ming Shen

Abstract

Put forward a way to use MATLAB when processing the image of the glass flowmeter in order to automatically get its float lever. In the process of image collection, we study the phenomenon of uneven background brightness that caused by illumination, and decide to use diffuse. First, we use MATLAB image processing toolbox, such as edge detection, filtering, thresholding, expansion, thinning, etc, and then add our own algorithms according to the specific image feature, to detect the float position.
