Installation

Dependencies

• Python version 3.5 or higher
• Zivid SDK version 1.3.0 or higher
• Compiler with C++17 support

Windows users also needs to make sure that the Zivid SDK installation folder is in system PATH before using the package, not only the terminal PATH variable. The default install location that should be added to system PATH is C:\Program Files\Zivid\bin.

Using PIP

The easiest way to install Zivid Python is to use PIP.

On some systems Python 3 pip is called pip3. In this guide we assume it is called pip.

When using PIP version 19 or higher build dependencies are handled automatically.

Installation may take some time since the setup.py script will download additional dependencies and compile C++ source code in the background.

pip install zivid

Old PIP

If you are using a version of PIP older than version 19 please manually install the dependencies listed in pyproject.toml before installing zivid.

pip install scikit-build cmake ninja
pip install zivid

Quick Start

Launch a Python interpreter and run the following code.

import zivid
app = zivid.Application()
camera = app.connect_camera()
frame = camera.capture()
frame.save("my-frame.zdf")

For more advanced usage see the Examples section.

Using camera emulation

If you do not have a camera, you can use the MiscObjects.zdf file in ZividSampleData.zip to emulate a camera.

import zivid
app = zivid.Application()
camera = app.create_file_camera("path/to/MiscObjects.zdf")
frame = camera.capture()
frame.save("my-frame.zdf")

Examples

Standalone example programs can be found in the samples directory.

Versioning

This python module is using PEP 440 for versioning. The features available in the module depends on the Zivid SDK version used when building the module. When updating this Python package it is recommended to also update to the latest Zivid SDK. Refer to the Test Matrix for supported version.

The version number of the Zivid Python module consists of six numbers. The three first numbers of the version is the semantic version of the code in this repository. The last three numbers is the version of the underlying Zivid SDK library used by the Python module.

Version breakdown

                                    Zivid SDK version = 1.4.1 (semantic version)
                                    v v v
Zivid Python module version = 1.0.0.1.4.1
                              ^ ^ ^
                              Wrapper code version = 1.0.0 (semantic version)
