Outline of Final Research Achievements |
To develop an automatic and continuous monitoring system for debris wood in rivers, we attempted to confirm whether image processing of thermography is available to detect the floating litter and debris wood on water surface in rivers. In this study, we conducted field measurement and laboratory experiments to compare the thermal and visible images for floating litters and evaluate the accuracy for detecting the floating litters. The results indicate that the image processing of thermography can detect the floating litters when there is the difference of temperature between water surface and floating litter. It is also noted that the processing processes with the binarization and sobel filter are useful to detect the floating litters by using appropriate parameters.
