In the use of cars, the lights play a role of fundamental importance in ensuring the safety of both the driver and all those who interact with him (other motorists, pedestrians, and cyclists).
Doubtlessly, the dazzling headlights mostly assure the clear identification of the figures the car encounters on its track but the main obstacle is represented by the glare of these other users within the light direction. To remedy this serious problem, cars hold dipped headlights, which do not annoy people at the outside but significantly impair the perceptibility at the inside.
In today's automotive industry, consequently, one of the main objectives is creating lights that both optimize visibility for the driver and do not damage the road control of other users.
A possible studied solution could be making the car lights becoming projectors: thanks to artificial intelligence algorithms able to recognize surrounding shapes and obstacles in the environment (similarly to what happens for self-driving vehicles), it will soon be possible to identify objects along cars' path and cast a shadow of their shape on them. This way, it would also be possible to use the high beam headlights without annoying the others, since the part of space occupied by them would no longer be illuminated.
In this field, however, the experimentation is still in its infancy and the involved technologies are numerous.
To verify new functionalities in this direction, DAVE Embedded System has been called to take part in the research: the main objective was to develop a product concept for car lighting, using already existing and tested technologies to innovate. For this project, therefore, two independent video streams integrated into a single stream were taken and, after processing, it was possible to play them in two different output displays, simultaneously and without latency: the innovation behind this creation is precisely this aspect, that is the ability to project two independent flows on two different screens in parallel.
The result is a demo adaptation of the System On Module AXEL LITE, provided with a carrier board: the related video is available at the following link:
DAVE Embedded Systems' KEY ROLE:
Thanks to its flexible and dynamic structure that allows experimentation on multiple prototypes, DAVE Embedded Systems started to develop one of these innovative solutions, through the AXEL Single Board Computers (SBC) evaluation kit. In particular, the demo features can be summarized as follows:
The resulting software based on the AXEL LITE hardware has been quickly developed, with efficient management of both video processing and latency.
ABOUT THE CUSTOMER:
Concerning this project, the customer Company works in the Automotive sector and, since it is interested in the search for new technologies to be applied to lights, it needed to determine what was possible to create through the development of these components. They, therefore, required to work alongside a quick, efficient and focused collaborator, salient features they found in DAVE Embedded Systems.
