產生目標

在此章節中，您會使用先前建立的模型 .pvz 檔案來產生目標；這些目標可以在多個體驗中重複使用。在此範例中，我們會使用標準模型目標，以便您更快速完成使用案例，但如果您有意願，也歡迎使用更強效的進階或內部部屬進階模型目標。

在多數情況下，請求結構會需要仰賴 Vuforia Engine SDK API 定義。如要了解具體的 Studio 指南，請參閱 Experience Service 上的 API 文件。

1. 請確保您配置的檢視符合模型目標的大小和定向。建立至少一個檢視，以容易辨識的明顯角度完整呈現模型，進一步最佳化偵測與追蹤效能。您可以使用下列任一方法在 API 上產生目標：

方法	指示
在 Postman 中	POST /ExperienceService/products/v1/target { "name": "Quadcopter Base", "targetType": "standard", "targetSdk": "10.9", "models": [ { "name": "Quadcopter Base SMT", "modelId": <Model-Id>, //take the UUID that the Post Model API returned in the last step "optimizeTrackingFor": "LOW_FEATURE_OBJECTS", "automaticColoring": "auto", "upVector": [0.0, 1.0, 0.0], "views": [ { "name": "viewpoint_0000", "layout": "landscape", "guideViewPosition": { "translation": [0.19104722142219543, 0.19300971925258636, 0.2014508694410324], "rotation": [-0.23911770032491195, 0.36964383294987413, 0.09904579601423466, 0.892399065690545] } } ] } ] }
使用 Curl 指令	curl --location 'https://<yourESURL>/ExperienceService/products/v1/target' \ --header 'X-Requested-With: any' \ --header 'Content-Type: application/json' \ --header 'Authorization: ••••••' \ --data '{ "name": "quadcopter base", "targetType": "standard", "targetSdk": "10.9", "models": [ { "name": "Quadcopter Base SMT", "modelId": "yourModelUUID", "optimizeTrackingFor": "LOW_FEATURE_OBJECTS", "automaticColoring": "auto", "upVector": [0.0,1.0,0.0], "views": [ { "name": "viewpoint_0000", "layout": "landscape", "guideViewPosition": { "translation": [0.19104722142219543, 0.19300971925258636, 0.2014508694410324], "rotation": [-0.23911770032491195, 0.36964383294987413, 0.09904579601423466, 0.892399065690545] } } ] } ] } '

在 Postman 中

POST /ExperienceService/products/v1/target

{
  "name": "Quadcopter Base",
  "targetType": "standard",
  "targetSdk": "10.9",
  "models": [
    {
      "name": "Quadcopter Base SMT",
      "modelId":  <Model-Id>, //take the UUID that the Post Model API returned in the last step
      "optimizeTrackingFor": "LOW_FEATURE_OBJECTS",
      "automaticColoring": "auto",
      "upVector": [0.0, 1.0, 0.0],
      "views": [
        {
          "name": "viewpoint_0000",
          "layout": "landscape",
          "guideViewPosition": {
            "translation": [0.19104722142219543,
              0.19300971925258636,
              0.2014508694410324],
            "rotation": [-0.23911770032491195,
              0.36964383294987413,
              0.09904579601423466,
              0.892399065690545]
          }
        }
      ]
    }
  ]
}

使用 Curl 指令

curl --location 'https://<yourESURL>/ExperienceService/products/v1/target' \
--header 'X-Requested-With: any' \
--header 'Content-Type: application/json' \
--header 'Authorization: ••••••' \
--data '{
  "name": "quadcopter base",
  "targetType": "standard",
  "targetSdk": "10.9",
  "models": [
    {
      "name": "Quadcopter Base SMT",
      "modelId": "yourModelUUID",
      "optimizeTrackingFor": "LOW_FEATURE_OBJECTS",
      "automaticColoring": "auto",
      "upVector": [0.0,1.0,0.0],
      "views": [
        {
          "name": "viewpoint_0000",
          "layout": "landscape",
          "guideViewPosition": {
            "translation": [0.19104722142219543,
              0.19300971925258636,
              0.2014508694410324],
            "rotation": [-0.23911770032491195,
              0.36964383294987413,
              0.09904579601423466,
              0.892399065690545]
          }
        }
      ]
    }
  ]
}

2. 回覆形式應類似下圖：

{
  "targetId": "<targetId>",    // Optional. Only sent in case when job to create Target is accepted.
}

3. 使用下列任一方法來取得模型目標產生的狀態：

方法	指示
在 Postman 中	GET /ExperienceService/products/v1/target/status/<targetId>
使用 Curl 指令	curl --location 'http://<yourESURL>/ExperienceService/products/v1/target/status/<yourTargetUUID>' \ --header 'Authorization: ••••••'

4. 回覆形式應類似下圖：

{
  "simplifiedStatus": "queued|inProgress|completed|failed|deleted|toBeCancelled|toBeDeleted",   // Dataset's current status
  
}

5. 重複執行步驟 1-4 以產生 Quadcopter Updated 模型的標準模型目標。請務必更新請求中的 modelId。

6. 建立好必備的資產後，我們將繼續前往下個章節，然後開始在體驗中建構資料邏輯。

這是否有幫助?
