Proprietary artificial vision technology assists drivers in their routine driving tasks by acting as a 'third eye'
 Mobileye is now embarking on developing sensing systems that do away with the need for radar fusion. The EyeQ2, which uses CMOS 90nm-micron technology operating at 332Mhz, is six to eight times faster, because it has more of our proprietary cores that allow simultaneous processing and analysis. Right now, we're working on a platform based on EyeQ2 that can deliver technology like forward warning vehicle detection, as well as motorcycle, pedestrian or bicycle detection, in addition to lane departure warning, high/low beam detection and traffic sign recognition on the same platform. So, by 2013-14, you will see city braking collision mitigation by vision only.
"Whilst stereo camera systems have a big advantage, in that it's easier to get depth of field, the detection range is shorter, and they need individual and joint calibration. With a mono camera, we will move to EyeQ3 and a higher definition sensor, with a better range of detection; currently, we can detect within 80-100 metres range. With the new system, that will increase to 150 metres - the same as radar.
ALL THE BENEFITS
"Mobileye is also developing a system called 'Stereo Assist'. The idea behind this is that you can have a stronger camera and assistance from a second cheaper camera that isn't calibrated with the first. It just gives assistance with depth of field, so you don't lose the range. It also uses the same processor and hardware, which helps with costs; so you get the benefits of a stereo system, with the cost benefits of a mono.
"With a high resolution sensor and stereo assist, our tests show that mono and stereo assist exceed twin camera systems. A single camera detects a car within the range of 120 metres and 35°. With this new system, a vehicle at night can be detected from 400 metres and more.
"In future, applications using artificial intelligence will allow the system to recognise new subjects and, if we then interconnect with other cars, they will learn from each other, constantly updating their databases."
The transition from light to dark – eg, into and out of a tunnel – is always a challenge, but Mobileye believes it has this beaten: "We employ a unique algorithm with Automatic Gain Control and, by using multiple exposure taking 12 frames per second and four different exposures, we get 48 images per second. In daytime, more data is taken from short exposures, but also from long ones, as the camera could be in shadow – like auto white balance on a digital camera. It takes less than 10-100 m/secs to adjust to in/out of tunnels, depending on circumstances, and it works the same way at night."
