Denso on August 10, 2016 for the news media held entitled "advanced technology development in the field of auxiliary driving and automatic driving" presentation, the company again, "to reliably recognize vehicles around, sensor fusion technology essential".
Sensor fusion technology's goal is to use a combination of characteristics of different variety of sensors, in all places around the vehicle identification accuracy. Denso proposed the combined use of cameras, millimeter wave radar, LiDAR (Light Detection and held, LiDAR) this three kinds of sensor solutions. Denso ADAS promote department minister said pine valley and blunt, automatic driving, "LiDAR is especially important.
In existing ADAS (advanced driving assistance systems, see this site) in the automatic braking function of the mainstream, the main focus is to use the camera and the existence of the millimeter wave radar object. And automatic driving also require identification for safety of free space (the "safe passage") in the graph. Therefore, denso think, want to hold space in three dimensional way, find out the free space on the direction, LiDAR is one of the most appropriate sensors.
Denso developing LiDAR, very early in 1996, the company developed LiDAR was equipped with the truck hino motors. This LiDAR for uniaxial scan type, for use in car from hours alert. Recently, the company developed a device for semiconductor will ever to realize the laser scanning products (semiconductor), equipped with the great light vehicle.
Although each kind of sensor technology in progress year by year, but in essence is still in a state of each have advantages and disadvantages. At present the ideal solution is to use a combination of three kinds of sensors. As for the use of the temperature of the body temperature to form different aspects, but at night the pedestrian detection exert power far infrared camera (thermal imaging and night vision), denso think through the combined use of visible light cameras and millimeter wave radar can cover related functions.
