Innovative advancements in AI technology promise major leaps in road safety through a remarkable new camera system perfected by researchers from the University of Zurich. This system melds cutting-edge biotechnology-inspired camera capabilities with the computational power of artificial intelligence, drastically outperforming current automotive cameras by detecting pedestrians in the vehicle’s path up to 100 times faster.
Drivers are all too familiar with the harrowing experience when a pedestrian unexpectedly steps onto the road, leaving them mere fractions of a second to react. While today’s vehicular camera systems can prompt a warning or trigger an emergency stop, they fall short of the reliability and speed required for fully autonomous vehicles.
Daniel Gerig and David Scaramuzza from the Department of Computer Science have strategically combined a biologically inspired camera with AI, designing a system that swiftly apprehends potential road hazards, significantly cutting down the computational power needed compared to existing systems.
Conventional cameras work on time-lapse photography, snapping 30 to 50 frames per second. The limitation lies in the delay between captures, which might cause a camera to miss rapid occurrences. Gerig points out that to address this, the frame rate could be increased, but this solution demands real-time processing of heftier datasets and much more computational capacity.
The Zurich team’s newly engineered cameras forgo constant frame rates, instead boasting smart pixels that capture information with the detection of quick movements. Termed as “neuromorphic cameras” for their mimicry of human vision, they can perceive impediments much faster without the constraints of conventional frame intervals.
However, slower-moving objects could evade these cameras, and their visual output is not readily convertible into data that AI algorithms can learn from. To counterbalance this, the researchers have developed a hybrid system, blending the strengths of both the neuromorphic and standard camera technologies:
The hybrid system uses a standard camera to capture a comparatively low 20 frames per second, processed by an AI-powered convolutional neural network trained to identify vehicles and pedestrians. It then combines this data with a different type of AI system, an asynchronous spiking neural network, particularly adept at analyzing three-dimensional, temporal data changes. The neuromorphic camera’s detections refine and enhance the performance of the traditional camera.
With the innovation tested, the team pitted their system against some of the top vehicular cameras and algorithms currently on the market. Their findings showed object detection was done 100 times quicker, reducing data transfer volumes and the computational power necessary for processing, without sacrificing accuracy.
This system especially shines by effectively spotting cars and pedestrians entering the visual field within the interval of two frames from a standard camera – a critical advancement for driver and pedestrian safety at high speeds – and is a potential keystone for the future security of autonomous driving. The researchers believe future improvements may merge this method with LiDAR sensors, similar to those utilized in self-driving cars, propelling this hybrid approach to the forefront of autonomous vehicle safety.
