- Abstract:
- The article presents a computer vision system for liquid level detection in standard capacity measures that can be used for automating measurements or preforming them in inaccessible places. The developed computer vision system consists of a digital camera and a computer program in the LabVIEW environment. The acquired images are processed and corrected for different distortions (parallax, lens and tilt distortion). By using the edge detection method, liquid level is detected and corrected for all distortions. The computer vision system was tested using water in a laboratory environment on the standard capacity measure with a nominal capacity of 100 l. The measurement results acquired with the automated computer vision system were compared with the readings made by an operator and the agreement is found to be satisfactory.
