日期:2017-03-13 13:20:48

 植物冠(guan)層分析儀利用魚眼(yan)鏡頭(tou)和CCD圖(tu)(tu)像傳感器來獲取植物冠(guan)層圖(tu)(tu)像。通過(guo)專業軟(ruan)件分析,獲得(de)植物冠(guan)層的(de)葉(xie)面(mian)積指(zhi)數(LAI)和冠(guan)層其它的(de)參數;自動(dong)水平數字相機獲取150°的(de)冠(guan)層圖(tu)(tu)像,手柄上24個PAR傳感器測(ce)量光(guang)合有(you)效(xiao)輻射并(bing)計算光(guang)斑。圖(tu)(tu)像法(fa)測(ce)量植物冠(guan)層,僅僅獲取一次冠層圖像即(ji)可(ke),簡化了傳統能量(liang)法要(yao)一天定點多次測量(liang)的繁(fan)復工作;同時(shi)可以(yi)躲開障礙物,選擇(ze)合適測量(liang)點。

主要功能(neng)

?  測(ce)量冠層葉面積指數(LAI),光(guang)合有效輻射值,計(ji)算(suan)太陽光(guang)斑

?  可調節鏡(jing)頭聚焦適合(he)不同高度(du)的冠層測量,從低矮植物到林木均可使用

?  鏡頭自動水平,一(yi)次(ci)成(cheng)像,測量不(bu)受天氣(qi)、光(guang)線影響(xiang),無需天空(kong)空(kong)白對(dui)照測量

?  無需(xu)在冠層頂(ding)部(bu)做參照測量(liang)

?  現(xian)場獲取植(zhi)物冠層彩色圖(tu)像,并直接(jie)(jie)顯示和儲存,強(qiang)大的(de)(de)冠層分析軟件功能,可以手(shou)動調節閾(yu)(yu)值、自(zi)動調節閾(yu)(yu)值(OTSU),現(xian)場評估冠層內(nei)的(de)(de)太陽直接(jie)(jie)輻(fu)射透過系(xi)數(shu)或LAI分析空隙系(xi)數(shu)。

?  軟(ruan)件設置天頂角和(he)方位角

?  用戶(hu)可(ke)通(tong)過分析軟(ruan)件進(jin)行(xing)天空(kong)和葉片進(jin)行(xing)顏色過濾

?  通(tong)過GPS和羅盤功能(neng)方(fang)便定位(wei),在(zai)植物生(sheng)長季過程定點(dian)重復測量

?  軟件(jian)進行屏蔽(bi)、躲(duo)開(kai)影(ying)響圖像計(ji)算(suan)結(jie)果的人影(ying)、天空等無用圖像

                                                                                        

測量參數

?  植物冠層葉面(mian)積指數(LAI)

?  葉片平均傾角(MLA)

?  散射(she)輻射(she)透過率(lv)(Transmission Coefficient)

?  消光(guang)系數(shu)(Extinction Coefficient)、直接輻(fu)射透過系數(shu)(Transmission Coefficient)、葉片分布(Leaf Distribution)

?  GPS定位信息(GPS Lock)

?  太陽(yang)光斑(Sunflecks)、光合(he)有效輻(fu)射(PAR)
