Stereolabs ZED - Matlab Integration
This sample shows how to use the ZED SDK functionalities within Matlab.
- First, download the latest version of the ZED SDK on stereolabs.com.
- For more information, read the ZED API documentation.
- Windows 7 64bits or later, Ubuntu 16.04
- Matlab with MEX compiler installed
- ZED SDK and its dependency (CUDA)
Build the program
Build for Windows
For detailed installation instructions, check out our documentation.
Build for Linux
Download the sample and execute the following command in a terminal:
export MATLAB_ROOT=/usr/local/MATLAB/R2012b # Put your actual Matlab path here mkdir build cd build cmake ../src make make install
Run the program
In the Matlab directory, open the file
ZED_Camera.m with Matlab and press run. Press any key to exit the program.
This sample is split into 3 parts, each of them shows a specific feature of the ZED SDK in Matlab.
In this part, we first initialize the ZED Camera and then retrieve both stereo images (Left and Right) as well as the depth data (32-bits float buffer) and the depth image normalized to 8-bits (grayscale). Then, with Matlab, we compute the depth histogram from the depth data values and display it.
This part shows how to get the positional tracking information. First, we initialize the ZED camera and the tracking, then we display the current left image as well as all the positions of the camera.
This part shows how to initialize the ZED camera and retrieve for each frame the current point cloud (X,Y,Z) of the scene. Then we use the mesh function of Matlab to display it.
This sample application is not designed to run in real time
On Linux, If you get the following error :
/usr/local/MATLAB/R2014a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.21` not found
Launch matlab with
You can also create an alias in a bash terminal (just once) to simplify the launch:
echo "alias matlab=LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.21:/usr/lib/x86_64-linux-gnu/libfreetype.so.6 matlab&" >> ~/.bashrc
Then just launch the application by typing:
