获取3帧后，Kinect 2流会卡住 [英] Kinect 2 streams get stuck after fetching 3 frames

问题描述

我正在使用Kinect v2并且有一个只显示正文和颜色流的小程序，但是在获取
仅3帧后，流停止发送帧。这是代码：

_sensor = KinectSensor.GetDefault();

        if (_sensor != null)
        {
            _sensor.Open();

            _reader = _sensor.OpenMultiSourceFrameReader(FrameSourceTypes.Color | FrameSourceTypes.Depth | FrameSourceTypes.Infrared | FrameSourceTypes.Body);
            _reader.MultiSourceFrameArrived += Reader_MultiSourceFrameArrived;
        }

以下是我如何获取帧

Console.WriteLine("==== FRAME FOUND ====");
        var reference = e.FrameReference.AcquireFrame();
        // Body
        using (var frame = reference.ColorFrameReference.AcquireFrame())
        {
            if (frame != null)
            {
                //stream.Children.Clear();
                var c_frame = reference.ColorFrameReference.AcquireFrame();
                ImageBrush ib = new ImageBrush();
                Image im = new Image();
                rgb.Source = frame.ToBitmap();
                var b_frame = reference.BodyFrameReference.AcquireFrame();
                _bodies = new Body[b_frame.BodyFrameSource.BodyCount];
                b_frame.GetAndRefreshBodyData(_bodies);
                if (_bodies[0].IsTracked)
                {
                    stream.DrawSkeleton(_bodies[0]);
                    if (recording)
                    {
                        recorder.RecordFrame(_bodies[0]);
                    }
                }
                b_frame.GetAndRefreshBodyData(_bodies);
            }
        }

推荐答案

你的逻辑不太正确。

Your logic isn't quite correct.

你是在不释放第一个颜色框架的情况下获取ColorFrame两次。你不应该一个接一个地直接获得两个颜色框架。

You're getting the ColorFrame twice without releasing the first color frame. You shouldn't be getting two color frames directly one after the other either.
