When I was in school, I really wanted a camera, but I still haven’t got my ideal camera. It’s a pity!
However, recently through the project recommended by GPT, I learned that there is still a great open source project in the world - Axiom Camera - that allows you to have your own machine. In this article, we will first introduce the project architecture, then how to DIY, and finally talk about why this is a great project.
introduce
AXIOM camera is a modular, open-source camera system launched by the German company apertus°. It consists of a core module and multiple modular components, which can be customized according to user needs. The camera uses software and hardware technologies in the public domain, and users can choose different lenses, sensors and processors according to their own needs to meet different application requirements.
This project is divided into three versions: AXIOM Beta developer kit, public version test version (compact version) and public version test version (extended version). At present, the design and testing of the first two versions have been completed, and the final expansion board is still in the preliminary design At this stage, you can follow the official website to check the latest progress.
Comparison of three versions
The latest version is under development
project structure
For learning and use, we focus on the AXIOM Beta Developer Kit, and commercial use can focus on the latter two versions. Today we will focus on how to use the AXIOM Beta Developer Kit.
Items needed are as follows:
The board assembly diagram is as follows:

Let's introduce the main hardware one by one:
sensor board
The sensor board is divided into two versions, with a seat and without a seat:
Sensor parameters:
CMOS
global shutter
APS-C/Super35 Diameter
12 megapixel (4096 x 3072) resolution
320 frames per second (8-bit), higher values at reduced resolutions, lower values at higher bit depths
8, 10 or 12 bit RAW output
PLR HDR dynamic range
5.5µm pixel size

Summarize
The greatness of some things lies not in its difficulty but in the value it brings, and the greatness of the AXIOM camera project is that it creates a new digital camera design concept, aiming to allow users to have a better experience in photography and post-production Great freedom and control.
Open source and transparent: AXIOM camera project is completely open source, users can view the working principle and source code of each component, which allows users to modify and customize the camera system freely. In addition, AXIOM camera provides very detailed documentation and tutorials to help users understand all aspects of the camera system.
Customizability: AXIOM camera is a highly customizable digital camera system, users can choose different sensors, lenses, processors and other components according to their needs, and combine them into their own camera system. This makes AXIOM camera a very flexible and suitable digital camera platform for various application scenarios.
High-quality video output: AXIOM camera uses high-quality sensors and lenses, which can produce very high-quality video output. In addition, the project also provides some advanced functions, such as RAW data output and support for high dynamic range (HDR), etc., which allow users to control the video production process more finely, resulting in higher quality videos.
Promote the development and innovation of digital imaging: The goal of the AXIOM camera project is to encourage and promote the development and innovation of digital imaging, giving users more freedom and control in photography and post-production. This will encourage people to experiment with new photography and post-production techniques and lead to more innovation and development.
