我正在使用Android firebase-ml-vision使用SurfaceView和相框的连续ByteBuffer扫描条形码。我以ML工具包快速入门项目作为起点，并且效果很好。
我项目的目的是识别与条形码关联的产品，并将其添加到扫描项目列表中。
相机对焦后，条形码处理器将多次检测到相同的条形码，因此您将在一秒钟内扫描20条而不是1条条形码。
这是来自CamereSource.FrameProcessingRunnable.run的 javadoc
Run Code Online (Sandbox Code Playgroud)* As long as the processing thread is active, this executes detection on frames continuously. * The next pending frame is either immediately available or hasn't been received yet. Once it * is available, we transfer the frame info to local variables and run detection on that frame. * It immediately loops back for the next frame without pausing.
我曾尝试在FrameProcessingRunnable中添加“已暂停”检查，但由于至少一个帧已被送入检测，因此我仍然至少两次被识别相同的条形码：
private class FrameProcessingRunnable implements Runnable {
private volatile …
