Mitsubishi Electric Develops Object-recognition Camera Technology
Using Proprietary AI for Coming Mirrorless Cars
Instant recognition of distant objects will enhance driving safety
TOKYO, January 17, 2018 – Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it hasdeveloped what is believed to be the industry’s highest performing automotive camera technology that detects
various object types at distances of up to about 100 meters, which will enable drivers to receive advanced
warning for enhanced driving safety in coming mirrorless cars. The solution, which is based on Mitsubishi
Electric’s proprietary Maisart-brand artificial intelligence (AI) technology, is expected to help prevent
accidents, especially when drivers change lanes. Mirrorless cars that replace rearview and side mirrors withcamera-monitoring systems were approved for use in Europe and Japan in 2016, and the first commercial
mirrorless cars are expected to be launched in Japan as early as next year.

Instantly detects distant objects up to about 100 meters away
- Mitsubishi Electric’s proposed technology employs a new computational visual-cognition model thatmimics human visual behavior to rapidly focus on appropriate regions within the field of view.
- Compared to conventional camera-based systems, the proposed technology, which is believed toachieve the industry’s highest performance, can significantly extend the maximum distance of object
detection from about 30 meters to 100 meters, and can also improve object detection accuracy from 14
percent to 81 percent.

Real-time object recognition using Mitsubishi Electric’s proprietary Maisart AI technology- The computational visual-cognition model’s relatively simple algorithms free system resources forreal-time performance, even in on-board systems.
- Mitsubishi Electric’s Maisart AI technology, which realizes compact AI for low-cost devices, candistinguish between object types such as pedestrians, cars and motorcycles.

Future Development- More robust performance for driving in bad weather, at night and on winding roads.
- Increased recognition accuracy by using time-series information.

Mirrorless cars that replace rearview and side mirrors with camera-monitoring systems were approved for use
in Europe and Japan in 2016. The first commercial mirrorless cars are expected to be launched in Japan next
year. Object-recognition systems will alert drivers to dangerous situations by detecting and identifying objects
in live video captured with on-board cameras.
