THP Entry: OpenMV


The future is a scary place, full of robots, drones, and smart appliances with cameras and vision systems that will follow your dog, your child, or your face around, dutifully logging everything they see, reporting back to servers, and compiling huge datasets that can be sold to marketing companies. We’re not too keen on this view of the future, but the tech behind it – cheap cameras in everything – is very cool. [Ibrahim] is doing his part to bring about the age of cheap cameras that are easy to interface with his entry to The Hackaday Prize, the OpenMV.

The idea of a digital camera that is easy to interface with microcontrollers and single board computers isn’t new. There are serial JPEG cameras and the CMUcam5 Pixy, but they cost somewhere around $70. It’s not something you would design a product around. [Ibrahim]‘s OpenMV costs about $15, and offers some interesting features like on-board image processing, a huge amount of RAM, and even a wireless expansion thanks to TI’s CC3000 WiFi module.

Currently, the OpenMV is capable of doing face detection at 25fps, color detection at better than 30fps, all thanks to the STM32F4 ARM micro running at 180MHz. There’s support for up to 64MB of RAM on board, with IO available through serial, SPI, I2C, USB 2.0, and WiFi.

It’s an interesting project on its own, but the really cool thing about this build is the price: if [Ibrahim] can actually produce these things for $15 a pop, he has an actual product on his hands, one that could easily be stuffed inside a drone or refrigerator for whatever cool – or nefarious – purposes you can imagine.
