如何根據 Excel 檔案中的編號來尋找影像？

Question

我的資料夾中有1,015 張圖像，該圖像分為七種類型，這些類型是皮膚癌醫學診斷的類別，相同的圖像在Excel 文件中按編號進行分類（每張圖片的編號對應於皮膚癌的類型）該影像的診斷）。顯然，每張圖像都有一個與診斷類型相對應的特定編號，我的問題是如何對資料夾中的這些圖像進行分組排序，以便每組圖像具有相同的診斷。

您可以在 powershell 中嘗試如下方法它當然可以優化，但我希望通過兩個步驟簡單地理解： - 第一個：根據您的輸入文件（.csv）創建目標樹 - 第二個：相應子目錄中的移動影像檔案）

#The process : 
$BasedImages = "\\path\to\ImagesDirectory"
$csvfile = "\\path\to\Inputcsvfile.csv"

#Gather all subfolders in the Images Directory (only first level) and put the name of these folder in a var. The only property useful for later use is the Directory name. Useless to gather all properties 
$ExistingSubDir = Get-ChildItem -Path $BasedImages -Directory | Select-Object -Property name

# Gather unique diagnosis in the input file and put in a var. The only useful property in the dx property for a later use. Useless to collect more info. 
$UniqueDiagnosis = Import-Csv -Path $csvfile | Select-Object -property dx -Unique

# gather all images files FullName in the Images Directory and put in a var. it seems that only  Name,DirectoryName, FullName properties will be usefull for later use
$AllImagesFiles = Get-ChildItem -Path $BasedImages -File | Select-Object -Property Name, DirectoryName FullName

# now First Step : build a Tree with  subfolders named by the unique Diagnosis name. 
foreach ($Diagnosis in $UniqueDiagnosis)
    { 
    # search if a diagnosis dir name (dx field in the input .csv file) exist in the ImageDirectory and put the result in a var
    if ($ExistingSubDir -contains $Diagnosis) 
        { 
        Write-Host "$ExistingSubDir is still existing, no action at this step" -ForegroundColor Green 
        }
    else
        {
        New-Item -Path $BasedImages -Name $Diagnosis -ItemType Directory
        Write-Host "a sub-directory named $Diagnosis has been created in the folder $BasedImages" -ForegroundColor Yellow
        }
    }

# At this step, you'll have some sub directories named with the name of all diagnosis (fied dx in the input file)
# Now Step 2 Time to move the files in the root folder
foreach ($image in $AllImagesFiles)
    { 
    $TargetSubDir = Get-Item -Path $($image.fullName)
    Move-Item -Path $($Image.FullName) -Destination ( Join-Path -Path (Split-Path -Path $($Image.DirectoryName) -Parent) -ChildPath $TargetSubDir)
    Write-Host "the image named $($image.name) has been moved to the sud directory $TargetSubDir" -ForegroundColor Green
    }

小心，我還沒有完全測試程式碼，請謹慎使用。
