Title:
TRANSPARENCY DETECTION METHOD BASED ON MACHINE VISION
Document Type and Number:
WIPO Patent Application WO/2022/247162
Kind Code:
A1
Abstract:
A transparency detection method based on machine vision. An intelligent Secchi disk and water gauge recognition technology based on image processing is provided. A conventional Secchi disk is combined with technologies such as image processing and deep learning, to accurately measure water transparency, thereby overcoming the shortcomings of errors in readings and inaccurate disk position determining caused by subjective and objective factors in a manual measurement process. The method is high in accuracy and stable and objective in numerical values, is not affected by subjective factors of individuals, and has very high application value.
