Application of Thermal Images for Determining the Vegetation Coverage Ratio at Free-Frame Shotcrete Grid Beam Protected Slope
National Chiayi University, Taiwan
2 Fifth District Maintenance Engineering Department, Highway Administration, Taiwan
In this study, infrared thermography was used to determine the vegetation coverage ratio (VCR) at a free-frame shotcrete grid beam-protected slope. An infrared thermal imager can detect the changes in surface radiation temperature on naked and vegetation-covered slope areas. Regional temperature analysis was performed through thermography, and the average temperature derived from the captured thermal images was used as the index for the vegetation area; the VCR was also evaluated. This method can be used in engineering practice after construction to reduce the errors in subjective visual judgment and can also serve as an effective and scientific evaluation methodology. A long-distance noncontact detection method for VCR evaluation can increase the engineering applicability of the proposed method after construction.
