概要 日本語  
英語 A method for extracting degraded trees was developed by using a near-infrared camera modified from a digital camera to photograph roadside trees. trees where the vegetation index are lower than other trees are considered a cautionary tree, and a tree where the vegetation index changes over time or month is lower than other trees is extracted as a degraded tree. To account for geometric accuracy, pixels were grouped together as blocks, and changes in vegetation indices from block to block were analyzed. As a result, blocks of debilitated trees were extracted from the trees along the road.
