ZED SDK sample to save the depth map as a file
Stereolabs ZED - Saving depth maps
This sample allows you to save depth information (depth map image and point cloud) provided by the ZED camera or an SVO file in different formats (PNG 16bit, PFM, PGM, XYZ, PCD, PLY, VTK).
Getting started
- First, download the latest version of the ZED SDK on stereolabs.com.
- For more information, read the ZED API documentation.
Prerequisites
- Windows 7 64bits or later, Ubuntu 16.04
- ZED SDK and its dependencies (CUDA, OpenCV 3.1)
Build the program
Download the sample and follow these instructions:
Build for Windows
- Create a "build" folder in the source folder
- Open cmake-gui and select the source and build folders
- Generate the Visual Studio
Win64solution - Open the resulting solution and change configuration to
Release - Build solution
Build for Linux
Open a terminal in the sample directory and execute the following command:
mkdir build
cd build
cmake ..
make
Run the program
Open a terminal in build directory and execute the following command:
./ZED\ Save\ depth [option]=[arg]
Example :
./ZED\ Save\ depth --resolution=3 --mode=2
Launch options
| Option | Descriptions | Available Arguments | Default Argument |
|---|---|---|---|
| --filename | SVO input filename (optional). | Path to an input SVO file | |
| --path | Specify the location to save image, depth and point cloud. | Output path | ./ |
| --resolution | Specify ZED video resolution. | "0": HD2K, "1" : HD1080, "2" : HD720, "3" : VGA | 2 |
| --mode | Specify depth map quality mode. | "1": PERFORMANCE, "2": MEDIUM, "3": QUALITY, "4": ULTRA | 1 |
| --device | If multiple GPUs are available, select a GPU device for depth computation. By default, (-1) will select the GPU with the highest number of CUDA cores. | GPU ID | -1 |
| --help, -h , -?, --usage | Display help message. |
