如何同步線程以捕獲相同數量的幀？

我正在開發一個Kinect應用程序。我有兩個線程，一個用於讀取關節的值（包含20個關節的x，y，z座標），另一個用於讀取深度值（每幀76800個短值）。我從按下開始按鈕開始記錄這些值，直到按下結束按鈕。我期望寫出相同數量的關節和深度的框架，但我總是以很多關節框架結束。我捕獲了150深度幀，但捕獲了180幀，我認爲這是因爲深度寫入緩衝區的數據量。關節每幀只寫60個花車，但深度爲76800短褲。如何同步線程以捕獲相同數量的幀？

我如何從每個捕獲等量的幀？

您使用哪些事件來捕獲數據？「AllFramesReady」與單個事件可能會幫助您同步數字。還可以看看CodePlex上的「Kinect Toolbox」項目;它提供了一個錄音機。 –

謝謝，但我正在開發C++和AllFramesReady不可用作爲C++中的事件 – user667222

具有由鎖和條件變量保護的共享表：

此日誌還示出了不相等叫每個線程的數目（用25至30 FPS超高動力學捕獲深度和座標）保持已捕獲的每種類型的幀數。如果其中一個線程發現它已經捕獲了比另一個更多的幀，就讓它阻塞在條件變量上。當任何線程完成獲取幀時，它會增加其類型的計數並廣播條件變量。

如何同步線程以捕獲相同數量的幀？
