Up detect.py のテスト : "webcam" モード 作成: 2021-05-05
更新: 2021-05-05

    PC から Raspberry Pi に ssh -X 接続。

    仮想環境で作業：
      ~ $ source ./venv/bin/activate (venv) $

    ストリーミング動画/Xウィンドウのテスト

    PC のデスクトップに，画像のウィンドウが開く。
    そして──何かの拍子で── 物体検出の枠が表示される：

      このビデオ画像は物体 (バッグ) 検出の簡単な場合に思えるが，物体検出の枠はなかなか現れてくれない。
      枠が現れるのは，ほんとうに「何かの拍子で」という感じである。

    cotrol + C で終了。

    備考
    つぎの起動失敗は，X接続が切れてしまっているときのパターン：
