# rs-imshow Sample

## Overview
|
|
This example is a "hello-world" code snippet for Intel RealSense cameras integration with OpenCV. The sample will open an OpenCV UI window and render colorized depth stream to it.
|
|
The following code snippet is used to create `cv::Mat` from `rs2::frame`:
|
|
```cpp
|
|
// Query frame size (width and height)
|
|
const int w = depth.as<rs2::video_frame>().get_width();
|
|
const int h = depth.as<rs2::video_frame>().get_height();
|
|
|
|
// Create OpenCV matrix of size (w,h) from the colorized depth data
|
|
Mat image(Size(w, h), CV_8UC3, (void*)depth.get_data(), Mat::AUTO_STEP);
|
|
```
