Teachable Machine

該文件詳細介紹了如何使用 Teachable Machine 進行圖像和姿勢分類，包括模型加載、分類、顯示結果以及將預測轉換為 JsonValue。 JsonValue

圖像

從 URL 載入自訂影像模型

圖像模型通過中止控制對視頻/攝像機中的對象進行連續分類

{"blocks":"<xml xmlns=\"https://developers.google.com/blockly/xml\"><block type=\"TeachableMachine_loadImageModel\"><value name=\"baseUrl\"><shadow type=\"text\"><field name=\"TEXT\"/></shadow></value></block></xml>"}

這用於從 URL 載入圖像模型。

參數： 字串（URL）
輸出： 模型預測結果（來自Teachable Machine圖像模型）
範例代碼：

這些模組可以在獲取圖像模型信息的同時顯示 Json 值結果。
