AM62A Edge-AI POE Camera¶
Overview¶
Critical Link has developed an application ready Carrier Board targeting the MitySOM-AM62A processor.
Features:
- Dual Power Options
- Power Over Ethernet (device)
- USB-C power
- Unit will default to POE power if both are provided.
- Video Streaming
- Micro-HDMI connector to 1080P HD
- Active H.264 encode and RSTP / network streaming via Gigabit Ethernet
- Camera Interface
- Up to x4 lanes of MIPI CSI
- Raspberry Pi Zero 22 pin camera interface
- IMX219 Based Raspberry Pi II camera
- Image Signal Processing
- Leverages Full ISP / tuning stack for TI AM62Ax processor*
- Active Debayering with edge enhancement
- HDR color mapping / scaling
- warp transforms (e.g., rotation, Lens distortion correction) and resizing
- White Balance
- Leverages Full ISP / tuning stack for TI AM62Ax processor*
- AM62A7 C7x256v DSP w/ MMA accelerated Deep Learning and Inferencing engine
- Supports object detection, facial recognition, segmentation
*Requires NDA with TI to access ISP tuning / firmware compiler
A block diagram of the carrier card is shown below:
The system is designed to run embedded linux based on TI's AM62A processor / Edge AI SDK and is capable of running all of the EDGE-AI example programs that are described on TI's Edge AI Demos Page from the AM62x Processor Linux Academy website.
The filesystem is stored on a 64 GB eMMC located on the MitySOM-AM62A. The eMMC may be updated using SSH / SCP, or using the USB-C interface via a Snagboot connection. Instructions for using snagboot can be found here.
Typical Power Consumption¶
Power measurements have been made using a USB-C power monitor. Ethernet and HDMI are connected and operating, but no power over ethernet is being delivered.
Scenario | Observed power Draw |
---|---|
Linux Booted. System IDLE but running TI's Edge AI menu application | 3.45 W max |
System Running TI's classification demo | 4.5W max |
The power draw will depend heavily on the DSP load.
Mechanical Information¶
Critical link has prepared A STEP model of the carrier board, MitySOM-AM62A, and camera board as shown in the image below. The model can be downloaded at this link.
Critical Link has designed a very simple enclosure to demonstrate a concept arrangement of the MitySOM-AM62A camera board set into a bullet style enclosure as shown in the pictures below. If a customer is interested in the mechanical model data for the enclosure please contact Critical Link at support@criticallink.com.
