With the introduction of the VRmDAVC-2, VRmagic offers an intelligent version of their established USB frame grabber. In combination with analog cameras, the intelligent frame grabber provides users with a powerful platform that can perform image processing tasks autonomously.

Built upon the established D2 platform, the VRmDAVC-2 is a programmable Linux based intelligent frame grabber platform. The D2 platform is characterized by a 300 MHz ARM9 processor, a 600 MHz DSP, 256 MB RAM, and 512 MB flash memory. Image data may either be processed directly in the intelligent frame grabber or transmitted via Ethernet for further processing. The embedded platform allows the direct connection of peripherals and control of equipment via RS-232 or GPIOs. “The VRmDAVC-2 can upgrade analog cameras to be an independent image processing system. Image processing tasks such as measuring and sorting can be accomplished autonomously and preprocessing tasks, such as run-length encoding or the generation of gradient images using a Sobel filter, can be outsourced. Further, the network load can be reduced by means of H.264 encoding, thus realizing an effective IP-based streaming camera solution.” explains Oliver Menken, Director of Imaging at VRmagic. “The outsourcing of image processing tasks from the main processor to the intelligent frame grabber streamlines the entire process, which is especially important for demanding applications.”

The VRmagic API offers convenient image data access from any PC. All VRmagic devices support the same API, making a future transition to an intelligent digital camera possible without additional programming.

The characteristics of the intelligent frame grabber are:
• PAL and NTSC resolution
• UBIFS file system
• pre-configured tool chain with cross compiler
• S-Video (input and output)
• Composite (input and output)
• Y/C input
• HDMI output adapter board (only OEM)
• 100 Mbit Ethernet on RJ45
• USB 2.0 host
• MPE-Garry Micro T connector for RS232/S-Video/composite/GPIOs
• Hirose DF14-15P for JTAG und serial console
• 5 V power supply

For OEM customers, the VRmDAVC-2 is available with a Pico interface board including a RGB888 interface. All interfaces of the standard interface board are as available on miniature connectors, thus reducing height and weight of the board.
