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(jìn)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(jìn)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(zhǔn)性；另外，附加 XLSTEM 可進(jìn)行植物的標(biāo)準(zhǔn)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(shí)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。
