Title: Liquid-level detecting method
Inventor: TSUNASHIMA NOBUHIRO
IPC: G06T1/00
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To accurately measure a liquid level with no use of a measuring plate or measuring column by extracting only a moving edge part which is then divided into a plurality of sections, and acquiring a peak value of the frequency histogram for the liquid level detected in each section. SOLUTION: A camcorder 1 images, for example, the water surface or wall surface of a water channel, and outputs it in monochrome image to a personal computer 2. An image signal is A/D converted 3 and sent to a CPU 4. An edge detecting means 6 scans the monochrome image for detecting a point where the brightness change in the image exceeds a pre-determined threshold. A moving edge detecting means 7 compares monochrome images taken at different times to each other so that the edges that change according to time such as the surface waves on the water surface are detected. A line segment detecting means 8 detects a water surface from a moving edge distribution image which is then divided into n-sections, and detects water level for each section for generating a frequency histogram.  A position of water surface which has the highest value in the histogram is taken as a water surface at that time.
