用intel realsense2顯示depth, ir影格

 intel realsense2顯示depth, ir影格。參閱realsense2 SDK所附範例與intel網站https://dev.intelrealsense.com/docs/api-how-to。顯影部份採openCV，C++程式碼如下：(深度資訊來自ir的資訊，intel 的深度攝影機D435有左右ir顯影，有視角差，可修改程式兩個畫面同時呈現)

#include <librealsense2/rs.hpp> 
#include <opencv2/opencv.hpp>  
using namespace rs2;
using namespace cv;
using namespace std;

int main(int argc, char** argv) try
{
    cout << "顯示depth, ir影格。\n";
    colorizer color_map(0);
    /*著色的代碼如下
     0 - Jet
     1 - Classic
     2 - WhiteToBlack
     3 - BlackToWhite
     4 - Bio
     5 - Cold
     6 - Warm
     7 - Quantized
     8 - Pattern
     9 - Hue
