使用C＃在.bin中写入深度图像 [英] Writing depth image in .bin using C#

问题描述

我想保存使用Kinect v2捕获的深度图像。我可以将图像保存在（.png，.tif，.gif等）中，但是保存数据需要花费很多时间，并且在保存时会遗漏一些帧。所以我想以.bin格式保存图像。这是我的深度图像代码：

< g class =" gr_ gr_19 gr-alert gr_gramm标点符号replaceWithoutSep"数据-GR-ID =" 19 QUOT; id =" 19">请任何人< / g>告诉我如何写出深度图像< g class =" gr_ gr_36 gr-alert gr_gramm标点符号multiReplace"
data-gr-id =" 36" id =" 36"> in。< / g> bin文件。

 
 IplImage depth = new IplImage（512,424，BitDepth.U16,1）; 
 CvVideoWriter DepthWriter; 
 Width = sensor.DepthFrameSource.FrameDescription.Width; 
 DHeight = sensor.DepthFrameSource.FrameDescription.Height; 
 WbDepth = new WriteableBitmap（DWidth，DHeight，96,96，PixelFormats.Gray16，null）; 
 int depthshft =（int）SliderDepth.Value; 
使用（DepthFrame depthframe = frame.DepthFrameReference.AcquireFrame（））
 ushort * depthdata =（ushort *）depth.ImageData; 
 if（depthframe！= null）
 {
 Depthdata = new ushort [DWidth * DHeight]; 
 ushort [] Depthloc = new ushort [DWidth * DHeight]; 
 depthframe.CopyFrameDataToArray（Depthdata）; 
 for（int i = 0; i< DWidth * DHeight; i ++）
 {
 Depthloc [i] = 0x1000; 
} 
 colorspacePoint = new ColorSpacePoint [DWidth * DHeight]; 
 depthspacePoint = new DepthSpacePoint [CWidth * CHeight]; 
 sensor.CoordinateMapper.MapDepthFrameToColorSpace（Depthloc，colorspacePoint）; 
 for（int y = 0; y< DHeight; y ++）
 {
 for（int x = 0; x< DWidth; x ++）
 {
 if（depthshft！= 0）
 {
 Depthdata [y * DWidth + x] =（ushort）（（Depthdata [y * DWidth + x]）<< depthshft）; 
} 
 
} 
} 
 depth.CopyPixelData（Depthdata）; 
} 
 WbDepth.WritePixels（new Int32Rect（0,0，DWidth，DHeight），Depthdata，strideDep，0）; 
 ImageDepth.Source = WbDepth; 
 if（depth！= null）
 {
 string s = string.Format（" {0}"，count_depth）; 
 Cv.SaveImage（" G：\\Kinect V2 Recording\\\\\\\\\\\\\\\\\\\\\\\\\; 
 
 
 count_depth ++; 
} 
 Cv.ReleaseVideoWriter（DepthWriter）; 
 CheckBox_saveD.IsEnabled = false; 
 if（CheckBox_saveD.IsChecked == true）Cv.ReleaseVideoWriter（DepthWriter）;

这不是同一个问题：

I want to save depth images captured using Kinect v2. I can save the images in (.png, .tif, .gif etc) but it took much time in saving data and it miss some frames while saving. So I want to save the images in .bin format. Here is my code for the depth image:

<g class="gr_ gr_19 gr-alert gr_gramm Punctuation replaceWithoutSep" data-gr-id="19" id="19">Please anyone</g> tell me how can write the depth image <g class="gr_ gr_36 gr-alert gr_gramm Punctuation multiReplace" data-gr-id="36" id="36">in .</g>bin file.

IplImage depth = new IplImage(512, 424, BitDepth.U16, 1);
CvVideoWriter DepthWriter;
Width = sensor.DepthFrameSource.FrameDescription.Width;
DHeight = sensor.DepthFrameSource.FrameDescription.Height;
WbDepth = new WriteableBitmap(DWidth, DHeight, 96, 96, PixelFormats.Gray16, null);
int depthshft = (int)SliderDepth.Value;
using (DepthFrame depthframe = frame.DepthFrameReference.AcquireFrame())
ushort* depthdata = (ushort*)depth.ImageData;
if (depthframe != null)
   {
    Depthdata = new ushort[DWidth * DHeight];
    ushort[] Depthloc = new ushort[DWidth * DHeight];
    depthframe.CopyFrameDataToArray(Depthdata);
    for (int i = 0; i < DWidth * DHeight; i++)
        {
          Depthloc[i] = 0x1000;
        }
        colorspacePoint = new ColorSpacePoint[DWidth * DHeight];
        depthspacePoint = new DepthSpacePoint[CWidth * CHeight];
        sensor.CoordinateMapper.MapDepthFrameToColorSpace(Depthloc, colorspacePoint);
        for (int y = 0; y < DHeight; y++)
            {
            for (int x = 0; x < DWidth; x++)
                {
                if (depthshft != 0)
                   {
                    Depthdata[y * DWidth + x] = (ushort)((Depthdata[y * DWidth + x]) << depthshft);
                   }

                 }
             }
         depth.CopyPixelData(Depthdata);
 }
WbDepth.WritePixels(new Int32Rect(0, 0, DWidth, DHeight), Depthdata, strideDep, 0);
ImageDepth.Source = WbDepth;
if (depth != null )
            {
                string s = string.Format("{0}", count_depth);
                Cv.SaveImage("G:\\Kinect V2 Recording\\depth\\depth" + s + ".png", depth);


                count_depth++;
            }
Cv.ReleaseVideoWriter(DepthWriter);
    CheckBox_saveD.IsEnabled = false;
if (CheckBox_saveD.IsChecked == true) Cv.ReleaseVideoWriter(DepthWriter);

Isn't this the same question:
