Harman, the audio, infotainment and connected tech company, has announced the development Reverse Pedestrian Detection tech – a new safety system to help eliminate the blind spots.
Blind Spots are believed to kill or injure 15,000 pedestrians a year in the United States.
The Reverse Pedestrian Detection combines data from existing Harman technologies fitted to the car, including a rear camera and sensor, to detect pedestrians behind the vehicle. One of its most critical uses is that it can successfully detect smaller children, aged between 12 and 23 months, who are most vulnerable to being hit.
“Despite the introduction of a range of safety technologies found in today’s cars and even with the most attentive drivers, ‘back over’ accidents cause too many deaths and injuries. Tragically, over 70 percent of incidents involving children are caused by a parent or relative behind the wheel,” explained Danny Atsmon, senior director of machine learning at Harman, who created the technology after realising his own two year old child could not be detected by existing sensor solutions.
The rising popularity of bigger vehicles such as SUVs has exacerbated the blind spot issue for consumers. Coupled with drivers placing too much reliance on the effectiveness of sensors and cameras, the tech company believes only by combining real-time sensory data with driver attention can the situation improve. The company’s new technology uses advanced computer vision methods and a fish eye camera to detect pedestrians behind the vehicle and fuses it with data from the ultrasonic sensors for close pedestrian verification. To improve the accuracy, the application also uses the steering wheel angle and speed for calculating probable collision trajectories.
“Reversing cameras certainly increase the driver’s field of vision, but there is still an area on either ride of the car that is not covered, and traditional reversing sensors are optimised to detect larger obstacles. No system is infallible, and the driver must still take caution, using mirrors or glancing over their shoulder. With the pedestrian detection system, drivers can reverse more safely with confidence,” added Atsmon.
“As we work toward bringing this software to automakers, we have adopted an approach that will enable the software to be housed in existing vehicle infotainment systems to minimise the cost and designed to fit into as many auto makers’ vehicles as possible,” summed up Atsmon.
