Metavision Assembly Kit – GenX320MP OPTICAL MODULE CM2 – STM32

Starter kit for STM32 with GenX320 320×320 event-based vision sensor for diverse embedded vision applications.

Connected to the STM32 Digital Camera Interface (DCMI) parallel interface, the GenX320 CM2 compact module offers a powerful solution for diverse embedded vision applications. This development platform enables experimentation with high-speed and low-latency event-based vision.

At its core, the GenX320 is a 320x320 6.3μm pixel BSI stacked event-based Metavision® sensor, designed for embedded vision and many power-sensitive applications. The GenX320 was explicitly designed to improve integrability and usability in at-the-edge vision systems. Key features include:

• Event data pre-processing and formatting
• Data interface compatibility
• Low-latency connectivity to processing platforms, including low-power neuromorphic processors

The sensor has been optimized for very low power operation, featuring a hierarchy of application-specific power modes. The GenX320 contains an integrated Event Signal Processing (ESP) pipeline, which includes:

• Timestamping
• Filtering
• Throughput regulation
• Data formatting functions

An Event Rate Controller (ERC) allows capping the output event rate to a programmable limit. A Spatio-Temporal Contrast filter (STC) detects and removes redundant bursts and trails of events triggered by high-contrast features in the scene. An Anti-Flicker (AFK) filter detects and filters events generated by flickering lights. The stop-band frequency can be set in the range of 50-500 Hz with arbitrary spans.
