如何使用NuiImageGetColorPixelCoordinateFrameFromDepthPixelFrameAtResolution将RGB图像与c ++中的深度图像对齐 [英] How to use NuiImageGetColorPixelCoordinateFrameFromDepthPixelFrameAtResolution to align the RGB image to the depth image in c++

问题描述

您好，我想将我的rgb图像与我的深度图像对齐，我正在尝试使用NuiImageGetColorPixelCoordinateFrameFromDepthPixelFrameAtResolution。我试图这样做，但它不起作用。深度图像的格式为uint8_t *，函数
需要USHORT *。所以我只需转换它：

 （USHORT *）DepthData;  

我需要帮助才能使用Kinect SDK v1.8中的内容将rgb图像坐标与深度图像坐标对齐，所以他们拍摄相同的东西，但我仍然希望它们是在不同的图片。这里有一些我尝试使用的代码没有
成功：

 
  uint8_t * Kinect :: calibrateRGBfromDepth（BYTE * RGBData，USHORT * DepthData）{
 
 LONG * RGBCoords =（LONG *）malloc（sizeof（LONG）* 640 * 480 * 2）; 
 
 sensor-> NuiImageGetColorPixelCoordinateFrameFromDepthPixelFrameAtResolution（
 NUI_IMAGE_RESOLUTION_640x480，
 NUI_IMAGE_RESOLUTION_640x480，
 640 * 480，
 DepthData，
 640 * 480 * 2， 
 RGBCoords）; 
 
 uint8_t * alignedRGBImage =（uint8_t *）malloc（640 * 480 * 4）; 
 
 //缺少一些代码，但RGBCoords没有给出正确的值，所以 
 
  //是NuiImageGetColorPixelCoordinateFrameFromDepthPixelFrameAtResolution内部错误。 
 
  
 return alignedRGBImage; 
}  
 

解决方案

使用坐标映射器：

Hello, I want to align my rgb image to my depth image and i am trying to use NuiImageGetColorPixelCoordinateFrameFromDepthPixelFrameAtResolution. I have tried to do like this, but it doesn't work. The depth image has the format uint8_t* and the function wants a USHORT*. So i just convert it with:

(USHORT*) DepthData;

I need help to use something in the Kinect SDK v1.8 to align the rgb images coordinates to the depth images coordinates, so they are filming the same stuff, but I still want them to be in different pictures. Here is a bit the code I was trying to use without success:

uint8_t* Kinect::calibrateRGBfromDepth(BYTE* RGBData, USHORT* DepthData){

    LONG* RGBCoords = (LONG*)malloc(sizeof(LONG)*640*480* 2);

    sensor->NuiImageGetColorPixelCoordinateFrameFromDepthPixelFrameAtResolution(
    NUI_IMAGE_RESOLUTION_640x480,  
    NUI_IMAGE_RESOLUTION_640x480,  
    640 * 480,                     
    DepthData,
    640 * 480 * 2,
    RGBCoords);

    uint8_t* alignedRGBImage = (uint8_t*)malloc(640 * 480 * 4);

    //Missing some code, but the RGBCoords doesn't give the right values, so something
//is wrong inside NuiImageGetColorPixelCoordinateFrameFromDepthPixelFrameAtResolution.

    return alignedRGBImage;
}

解决方案

use the coordinate mapper:
