This is just an idea for OpenMV to think about.
The Lego Mindstorms is a very very large community that is also used to paying Lego prices for their hardware. There has been a couple of after market machine vision cams released for minstorms. NXTcam was the most liked and pixy cam have a Lego interface as well. The picy cam was less liked because the Lego community didn’t like that it didn’t have a case and electronics was exposed for kids to damage. The NXTcam was much more liked but the interface was only for NXT and when next generation EV3 was released using lab view to program it there isn’t any interface for the Lab View.
The Lego interface with pixy cam can only do (x,y,w,h) first colour blob detected. I have used and tested it myself.
I haven’t used NXT cam as have never owned the Lego NXT but I believe it does colour blob tracking and line following.
The biggest option the Lego community keeps asking for is face detection. If there was a Lego version of OpenMV with face detection, colour blob tracking and line following it would be the best Lego machine cam on the market.
I believe Lego EV3 can recieve sensor data from sensors via UART or I2C.
I think that if OpenMV was to make a Lego Labview interface that it could sell a lot of cams to the Lego community at a slightly higher price to cover the cost of developemnt to the lego version.
