Shadow Detection in Slope Monitoring Based on Digital Image Processing

摘要: At present, the traditional slope monitoring technology is relatively backward. Shadow detection has always been difficulty and focus of this in monitoring. In recent years, digital image processing developed rapidly, which provides possibility to solve difficult problem. Therefore, paper proposes shadow research based on processing. paper, digitization our country are deeply studied. The results show that measurement method obvious advantages over method, improved accuracy, operation staff safety. According actual needs monitoring, combined with characteristics corresponding optimization adjustment made. A algorithm saturation proposed. Compared algorithm, simplifies calculation steps improves accuracy calculation. addition, order ensure effect, also establishes indicators, evaluates from rate, false alarm rate missing rate. further verify effect comparative experiments carried out. experimental model higher than DGM model, more suitable for current land environment China.
