Stereolabs ZED - OpenCV

This sample is the perfect place to get started coding with the ZED and OpenCV. It shows how to:

• Capture image, depth and point cloud from the ZED.
• Convert image and depth map to compatible 32-bits float OpenCV matrix.
• Display video and depth with OpenCV.
• Adjust several depth parameters: depth sensing mode, quality, units, resolution.
• Save side by side image, depth image and point cloud in various formats

Getting started

• First, download the latest version of the ZED SDK on stereolabs.com.
• For more information, read the ZED Documentation and API documentation or our Community page

Prerequisites

• Windows 10, Ubuntu LTS
• ZED SDK and its dependencies (CUDA, OpenCV)

OpenCV can be installed from source on Linux, please refer to this guide to proceed with the installation.

C++

Read the guide to learn how to build and launch this sample in C++.

Python

Installing OpenCV

Installing OpenCV on Windows

OpenCV provides already compiled binaries, it can be downloaded at https://opencv.org/releases/

Installing OpenCV on Linux

Some sample can require OpenCV, here is a tutorial on how to install it.

OpenCV can be downloaded at this location : https://opencv.org/releases/

For a more detailed OpenCV tutorial installation, refer to the opencv documention.

Installation steps

• Install the required dependencies

sudo apt-get install build-essential cmake libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

• Download source archive from http://opencv.org/releases.html and extract it

wget https://github.com/opencv/opencv/archive/4.1.0.zip -O /tmp/opencv_src.zip
cd ~/
unzip /tmp/opencv_src.zip ; rm /tmp/opencv_src.zip

• Navigate to the extracted sources, create a temporary build directory and enter it. For example,

cd ~/opencv-*
mkdir build
cd build

• Run cmake

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF -DBUILD_EXAMPLES=OFF -DBUILD_JAVA=OFF -DWITH_OPENGL=ON ..

• Execute make. The compilation can take a while

make -j$(nproc)

• Install the libraries

sudo make install
