The most appropriate group to review this material would be Embedded Vision Systems Architects and Industrial Automation Engineers. These professionals specialize in the integration of image sensors, signal processing pipelines, and high-speed data interfaces for manufacturing, robotics, and research.
Expert Summary: CHC5 Open Machine Vision Platform
Abstract:
The CHC5 is a modular, open-source, and programmable industrial camera platform designed to address the limitations of proprietary, "black box" machine vision systems. Developed over four years, the architecture decouples the image sensor, processing logic, and physical interface, allowing for extensive hardware customization and full transparency in software and firmware. The system supports a wide array of MIPI D-PHY, LVDS, and SLVS sensors up to 35 Megapixels, utilizing an Image Signal Processor (ISP) capable of 600 Megapixels per second. By offering interchangeable lens mounts (including RF and M42) and standard streaming protocols like GigE Vision and USB3 Vision, the CHC5 provides a flexible substrate for high-speed acquisition and custom edge-processing applications.
Technical Specifications and Modular Architecture
Modular Hardware Design: The system features a decoupled architecture where lens mounts, image sensors, and interface boards are interchangeable. This allows users to modify individual functional blocks or upgrade specific components without replacing the entire system.
High-Speed Processing (ISP): The internal Image Signal Processor (ISP) supports a processing rate of 600 Mpixel/Second. Maximum frame rates are resolution-dependent:
640x480: ~2000 FPS
1080P: ~170 FPS
4K: ~40 FPS
Sensor Compatibility and Interface: The platform supports sensors up to 35MP via MIPI D-PHY, LVDS, or SLVS interfaces. It accommodates up to 8 data lanes (10Gbps total bandwidth) and can interface with up to two sensors simultaneously. Supported pixel formats include RAW8, RAW12, and RAW14.
Available Sensor Options:
Rolling Shutter: Includes IMX477 (12.3M), IMX678 (8.4M low light), IMX585 (8.4M large pixel), IMX283 (20.3M 1-inch), and IMX294 (10.7M 4/3 format).
Global Shutter: Includes IMX568 (5.1M) and IMX565 (12.3M).
Optical Versatility: The camera maintains a minimum flange distance of 12mm, compatible with C-Mount, CS-Mount, RF-Mount (manual), M42, and M43 mounts. It includes an internal user-changeable IR cut filter and an external 43mm standard filter mount.
Connectivity and Protocols:
USB3 (5Gbps): Supports UVC and USB3 Vision protocols.
Ethernet (1Gbps): Supports GigE Vision.
HDMI: Provides 1080p output.
Auxiliary I/O: The unit includes one isolated input and one isolated output, both user-configurable for industrial triggering and synchronization.
Open Source Philosophy: The platform provides full access to firmware and software, aimed at reducing vendor lock-in, enhancing data privacy, and allowing developers to customize processing pipelines for specific robotics or research requirements.
