How to fix error "nivisocvsamples. dll" on NI LabVIEW Vision OpenCV Utilities

national_instruments_nivision_opencv_utilities-1.0.0.47安裝后在vision模塊中放置VI后如果提示找不到nivisocvsamples.dll，

需要在Call Library Function Node中手動指定其路徑，C:Program Files (x86)National InstrumentsNIVision OpenCV Utilitiesnivisionextlibsamplesx86vc140binnivisocvsamples.dll

選取后如果提示找不到nivisext.dll，需要把C:Program Files (x86)National InstrumentsNIVision OpenCV Utilitiesnivisionextlibx86vc90bin路徑下的nivisext.dll文件複製到C:Program Files (x86)National InstrumentsNIVision OpenCV Utilitiesnivisionextlibsamplesx86vc140bin路徑。

再次指定vi的nivisocvsamples.dll路徑，如果提示缺少tbb.dll則把C:Program Files (x86)National InstrumentsNIVision OpenCV Utilitiestbbx86bin裡面的文件複製到C:Program Files (x86)National InstrumentsNIVision OpenCV Utilitiesnivisionextlibsamplesx86vc140bin。

再次指定vi調用的nivisocvsamples.dll路徑已經是可以運行狀態。
