Research on Water Level Gauge Image Identification Based on Intelligent Remote Viewing

摘要

To research water level gauge image identification based on intelligent remote viewing system which can replace the on-duty staff observing, an improved Otsu algorithm is proposed to realize higher identification accuracy. The new Gaussian difference filter is also applied to image edge detection for later period clearly dividing and extracting the liquid level and the scale numbers of water level gauge so that the liquid level scale can be obtained fast and accurately. The result of the experiment shows that the proposed intelligent remote viewing system and algorithms not only have higher intelligent degree, but also can improve apparently image identification effect.
