    摘要:

    針對(duì)現(xiàn)有測量植物葉片面積方法會(huì)對(duì)葉片造成一定程度的損傷，提出一種直接對(duì)自然生長狀態(tài)下的葉片進(jìn)行測量的方法。首先，對(duì)數(shù)碼相機(jī)進(jìn)行校正獲取相機(jī)參數(shù)，從多角度拍攝自然生長狀態(tài)下的葉片；然后，利用PhotoModeler軟件對(duì)圖像進(jìn)行處理，獲得葉片三維點(diǎn)云模型；再利用Matlab編程實(shí)現(xiàn)葉片的三維曲面建模并計(jì)算曲面面積。將該測量結(jié)果與采用掃描儀結(jié)合Photoshop測量結(jié)果進(jìn)行了對(duì)比，實(shí)驗(yàn)結(jié)果表明，提出的方法對(duì)自然狀態(tài)下的葉片測量效果良好，精度達(dá)99%。

    Abstract:

    The existing methods of leaf area measuring would cause certain damage to the leaf, so a measurement method of the leaf area in natural growing state was put forward. The digital camera was calibrated to get camera parameters; then leaf images at various angles in natural growing state were shot and processed by PhotoModeler software. The 3-D point cloud model of leaf was built up. The 3-D surface modeling and surface area calculating of leaf were achieved by using Matlab software. The measuring results and the calculating results with combination method of scanner and Photoshop software were compared. It showed that the accuracy of calculating results reached to 99%.
