Overview

This project contains yet another Photobooth. The software is intended to run on a Raspberry Pi 2 and upwards, but it can run on any linux PC. A preview image is displayed in capture mode. After countdown, a picture is taken and can be discarded or saved. Saved images can be printed immediately or printed collage image with multiple photos. All saved images are shown on front page when the photobox is idle.

As image source a DSLR over GPhoto2 or a V4L2 camera (Raspberry Pi Camera or webcam) can be used.

The application can be either compiled and deployed on an existing Raspberry Pi OS installation, or a ready to go image can be build by Yocto build system: https://github.com/saeugetier/poky-photobooth/

Software

Framework: Qt 5.9 or higher - https://qt.io

By default V4L2 are used. If you use a Raspberry Pi Camera, the v4l2 camera kernel module must be used.

In order to use GPhoto2 cameras, the QT Multimedia Gphoto Plugin must be installed. A list of supported cameras can be trieved from the GPhoto2 website.

The software can be build to run on a local PC. Or it can run on an Raspberry Pi. In order to get the best performance and integration, the recipes for Yocto can be used: https://github.com/saeugetier/poky-photobooth
