摘要: PURPOSE:To provide a method and apparatus for measuring the water level reliably simply based on image from gauge while eliminating erroneous recognition caused by shadow. CONSTITUTION:The of 1 liquid 10 with eye is picked up means an ITV camera 2. The then converted through 31 into gray thereof accumulated in horizontal direction 32. border position where varies significantly detected histogram representing vertical direction. When variation exceeds threshold value, determined predetermined (downward) displayed screen monitor 4 so that it can be discriminated 1.
