A $20 Rockchip board gives Arduino robots stereo vision
I Built a Stereo Vision Board for Hardware Hackers
Ryan Walker built a cheap stereo vision board around the Rockchip RV1103, a 1.1 GHz Cortex-A7 SoC with 64 MB RAM and a MIPI CSI-2 bus in a QFN-88 package. The four-layer PCB runs Buildroot Linux, captures images from two OV9281 cameras, and uses the chip's hardware SAD engine for block-matching depth. It streams data over serial for robots or runs standalone. He'll order ten fixed boards if 20 people sign up.
I tend to get excited about certain chips. This time, it was a microprocessor: The Rockchip RV1103 is a single-core 1.1 GHz ARM Cortex-A7 SoC with 64 MB of DDR2 RAM and a MIPI CSI-2 bus shoved into a QFN-88 package.
