| Zusammenfassung: | The present invention provides a diagnosis and prediction system for dying of trees after a forest fire, which may include: an image acquisition unit (10) for taking pictures of trees in all directions after a forest fire; an image analysis unit (20) for analyzing the height of the tree and the soot area from the acquired image; an independent variable extraction unit (30) for calculating a soot index (BSI) and a breast height diameter (DBH) from the analyzed image; and a mortality rate calculation unit (40) for receiving the calculated BIS and DBH to calculate the mortality rate of the tree.
본 발명은 산불 후 수목의 사방위 사진을 촬영하는 이미지획득부(10); 상기 획득된 이미지로부터 수목의 높이 및 그을음 영역을 분석하는 이미지분석부(20); 상기 분석된 이미지로부터 그을음지수(BSI)와 흉고직경(DBH)을 산출하는 독립변수추출부(30); 및 상기 산출된 그을음지수(BSI)와 흉고직경(DBH)을 입력받아, 수목의 고사율을 산출하는 고사율산출부(40)를 포함하는 산불 후 수목의 고사여부 진단예측시스템을 제공한다. |
