rs-hello-realsense（C++）（调用摄像头显示中心深度距离）
Demonstrates the basics of connecting to a RealSense device and using depth data
realsense_test.cpp
#include <stdio.h>
#include <iostream>
#include <librealsense2/rs.hpp> // Include Intel RealSense Cross Platform API
int main()
// Create a Pipeline - this serves as a top-level API for streaming and processing frames
rs2::pipeline p;
// Configure and start the pipeline
p.start();
// Block program until frames arrive
rs2::frameset frames = p.wait_for_frames();
// Try to get a frame of a depth image
rs2::depth_frame depth = frames.get_depth_frame();
// Get the depth frame's dimensions
float width = depth.get_width();
float height = depth.get_height();
// Query the distance from the camera to the object in the center of the image
float dist_to_center = depth.get_distance(width / 2, height / 2);
// Print the distance
std::cout << "The camera is facing an object " << dist_to_center << " meters away \\r";
return 0;
运行结果：
The camera is facing an object 3.602 meters away
Distance（C）（测试depth流）（SDK里少了example.h文件，搞不了[我勒个去，它没集成在安装包里面，要下source code才有这个文件]）
Equivalent to hello-realsense but rewritten for C users
Intel® RealSense™ SDK 2.0 (v2.49.0)
直接把这个文件拷到项目工程文件夹下，跟.c文件放在一起
然后编译运行，一次成功（中间还有个小插曲，就是realsense2.dll文件是2.48的，但是最新的是要求2.49的，所以第一次运行没成功，把2.49的realsense2.dll拷过去就运行成功了）

运行结果：
Capture（C++）（显示color和depth图）（裂开，官方给的要引用的库还得自己编译！）（还有不要用官网上那个不全的代码，要用source code里的代码！）
Shows how to synchronize and render multiple streams: left, right, depth and RGB streams
example.hpp不能直接拷贝到源码文件夹下，要指定路径引用
裂开，各种报错
不用安装包的文件了，直接用source code
悄悄告诉你，文件夹名字为include的极有可能是需要你包含的。。。😅，，，比如这个
经过同事的点拨，终于知道为啥报错了，因为还有一些关于其他比如opencv的头文件、库没包含进去。。。
要把这三文件里的内容都给加进去，为了方便，就不手动添加了，直接把这三加进属性表管理器里（添加顺序没有要求！）
然后编译还是不行，报错！
通过报错的情况来看，应该跟glfw这玩意有关
在SDK中找到第三方库，发现这货居然没编译（没有生成.lib或.dll文件）
幸好它有工程项目文件，打开它直接用VS编译
编译后生成了glfw-imgui.lib文件
把它的文件名和它所在的目录分别添加到属性页的输入-附加依赖项和常规-附加库目录中
然后编译运行程序，大功告成
