High-Speed Image Acquisition and Gigapixel Processing in Vision Systems

High-Speed Image Acquisition in Modern Vision Systems

High-Speed Image Acquisition has become a central requirement in modern machine vision and imaging systems. High-resolution and high-frame-rate cameras can generate several gigapixels per second, creating significant demands on acquisition bandwidth, memory, processing, storage, and downstream computing.

A system processing several gigapixels per second must continuously acquire, move, and often preprocess billions of pixels every second without dropping frames.

Maintaining real-time performance requires more than a fast camera interface. The complete acquisition path must sustain the incoming data rate while preserving deterministic timing, low latency, and reliable image transfer.

Why Gigapixel Data Rates Create Acquisition Bottlenecks

As camera resolution, frame rate, bit depth, and camera count increase, imaging systems must continuously move and process much larger data streams.

High-bandwidth interfaces such as CoaXPress, GigE Vision, and Camera Link can deliver large volumes of image data into the system. However, acquisition is only the first stage. The architecture must also handle buffering, preprocessing, image enhancement, compression, memory transfers, and application processing without losing frames.

This is especially challenging when the system must process multiple gigapixels per second while maintaining predictable latency.

FPGA Architecture for High-Speed Image Acquisition

FPGA-based acquisition allows image data to move directly from the camera interface into dedicated processing logic.

The FPGA can handle deterministic acquisition, protocol processing, buffering, timing, image preprocessing, and data preparation before transferring image data to the host CPU, GPU, or embedded processor.

This architecture helps reduce the amount of acquisition and pixel-processing work performed by general-purpose processors. As a result, CPU and GPU resources remain available for AI inference, application logic, visualization, and other higher-level workloads.

Real-Time FPGA Preprocessing Before the CPU or GPU

High-speed acquisition becomes more efficient when pixel-intensive processing occurs close to the camera input.

The FPGA can perform operations such as image correction, HDR, compression, filtering, buffering, and data preparation directly within the acquisition pipeline.

Processing data before it reaches the CPU or GPU can reduce downstream memory traffic and processing requirements while maintaining deterministic real-time operation.

Reducing Gigapixel Data with FPGA Compression

High-speed imaging systems can also generate significant storage and network demands. Real-time compression helps reduce the amount of image data that must move through the rest of the system.

Gidel’s FPGA Image Compression IPs operate directly within the FPGA processing pipeline.

For applications requiring high image quality with substantial data reduction, Quality+ Compression can reduce bandwidth and storage requirements while maintaining high image quality.

High-Speed Image Acquisition with Edge AI

Gidel’s FantoVision Edge AI Systems combine high-bandwidth FPGA acquisition and processing with NVIDIA Jetson computing.

The FPGA handles deterministic camera acquisition and pixel-intensive processing before transferring image data to the Jetson. This leaves more CPU/GPU resources available for AI inference, detection, tracking, classification, and application processing.

High-Bandwidth Camera Interfaces

Different high-speed image acquisition systems require different camera interfaces depending on bandwidth, distance, cabling, synchronization, and system architecture.

Gidel supports high-bandwidth acquisition through:

• CoaXPress Frame Grabbers for very high-bandwidth acquisition, including CXP-12
• GigE Vision Frame Grabbers for flexible Ethernet-based high-speed imaging
• Camera Link Frame Grabbers for deterministic industrial camera acquisition

Gidel’s acquisition platforms can acquire directly from high-bandwidth CoaXPress cameras, GigE Vision cameras, and Camera Link cameras. This allows FPGA-based acquisition and processing to match different bandwidth, cabling, and system requirements.
