采集返回人脸数1，但采集的数据不正常，代码如下

Baidu_FaceApi.sdk_init("7832829A-90D6-4159-face-winandlinux-test");
Baidu_FaceApi.is_auth();
Baidu_FaceApi.get_device_id();
Baidu_FaceApi.set_min_face_size(30);
Task.Factory.StartNew(() =>
{
using (VideoCapture cap = new VideoCapture(CaptureDevice.Any))
{
Mat image = new Mat();
while (true)
{
cap.Read(image);
if (image.Empty()) return;

TrackFaceInfo[] faceInfos = new TrackFaceInfo[1];
IntPtr ptT = Marshal.AllocHGlobal(Marshal.SizeOf(typeof(TrackFaceInfo)));

int faceCount = Baidu_FaceApi.track_max_face_by_mat(ref faceInfos, image.CvPtr);
if (faceCount > 0)
{
IntPtr ptr = new IntPtr();
if (8 == IntPtr.Size) ptr = (IntPtr)(ptT.ToInt64());
else if (4 == IntPtr.Size) ptr = (IntPtr)(ptT.ToInt32());
faceInfos[0] = (TrackFaceInfo)Marshal.PtrToStructure(ptr, typeof(TrackFaceInfo));

Console.WriteLine(JsonConvert.SerializeObject(faceInfos[0]));
}
Cv2.ImShow("face", image);
Cv2.WaitKey(1);
}
image.Release();
}
});

结果如下
