主要功能
WinDENDRO 年輪圖象分析系統(tǒng)是一款多平臺圖象分析系統(tǒng),與掃描儀匹配,專門對盤狀的木材截面或柱狀的生長錐樣本進行樹木年輪的測量。
大型木材樣本可在不同部位多次分別成像;特殊的樹芯定位器用以放置柱狀樣本;兩種自動測定年輪的方法分別適用于不同的樹木類型;人工輔助的圖像識別校正和遺漏像素添加功能;可利用木材薄片的 X 光膠片掃描進行木材密度測定( 密度版)。此外,WinDENDRO 可自動設(shè)置裂縫與年輪角度的切線,以保證測量的精準性;另外,附加 XLSTEM 可進行植物的標準生長分析,如莖干平均半徑、直徑以及總體截面積;樹木高度、體積、樹齡等。對于所分析的年輪圖像可同時顯示如下參數(shù):年輪寬度、早材/夏材寬度、年輪最大/最小密度/平均密度、早材/夏材平均密度(高級密度版)等。
