Abstract:
A system for fluid flow verification comprises a video recording device that captures frames of actual fluid or fluid display, and a processor coupled to the recording device. The processor hosts fluid verification modules, including a fluid flow rate verification module, and a fluid color verification module. The fluid flow rate verification module is operative to receive the frames; binarize region of interest, and compute histogram of white/black pixels; count white pixels to detect actual fluid quantity; determine whether actual fluid quantity matches expected fluid quantity; if there is a match, measure fluid change rate; determine whether there is steady fluid flow; if not, report fluid flow rate anomaly. The fluid color verification module is operative to: receive binarized region of interest and histogram; detect fluid color by extracting sample color mask of pixels; determine whether detected fluid color matches expected fluid color; if not, report fluid color anomaly.
