Visual Gesture Builder - DiscreteGestureResult问题 [英] Visual Gesture Builder - DiscreteGestureResult Problem

问题描述

我使用提供的示例尝试编写自己的使用Visual Gesture Builder的应用程序。我知道我的数据库工作正常，因为我能够将数据输入到坐着的示例中，并且它没有问题。使用断点我有
设法将问题缩小到以下代码。

I have used the provided samples to attempt to write my own applications that used Visual Gesture Builder. I know my database works correctly as I was able to input the data into the seated example and it worked without a problem. Using break points I have managed to narrow the problem down to the following code.

引发的异常是DiscreteGestureResults为空。

The exception that is thrown is that DiscreteGestureResults is null.

任何想法？

        public void GestureFrameArrived(object sender, VisualGestureBuilderFrameArrivedEventArgs args)
        {
            VisualGestureBuilderFrameReference frameReference = args.FrameReference;
            using (VisualGestureBuilderFrame frame = frameReference.AcquireFrame())
            {
                if (frame != null)
                {
                    var resultBT = frame.DiscreteGestureResults[BottomToTop];
                    var resultTB = frame.DiscreteGestureResults[TopToBottom];
                    var resultRL = frame.DiscreteGestureResults[RightToLeft];
                    var resultLR = frame.DiscreteGestureResults[LeftToRight];
                    var resultIO = frame.DiscreteGestureResults[InToOut];
                    var resultOI = frame.DiscreteGestureResults[OutToIn];

                    if (resultBT.Detected == true)
                    {
                        if (resultBT.Confidence > 0.35)
                        {
                            GestureOut.Text = resultBT.Detected ? "BottomToTop" : "None";
                            //ConfidenceText.Text = resultBT.Confidence.ToString();
                        }
                    }

推荐答案

在帧上，不会检测到每个手势。您列出的所有6个手势是否为空，或者只有BT结果在失败时为空？

On a frame, not every gesture would be detected. Are all 6 of the gestures you have listed null, or only the BT result null for the time it fails?
