ADAS algorithm for creating a wider view of the environment with a blind spot display for the driver

Abstract

Examining the blind spot of the vehicle while driving using the vehicle mirror and looking over the shoulder causes a critical time when the driver does not have an overview of the environment in front of the vehicle, which can be the cause of traffic accidents. For that reason, this paper presents the implementation of the solution for stitching multiple frames with the overlap area, obtained by vehicle cameras with the aim of increasing the visibility of the environment behind the vehicle and eliminating the need for a classic view over the shoulder. A real ADAS (Advanced Driver-Assistance System) development board and the three real automotive cameras were mounted on a small vehicle model and were used to create test videos. After frame stitching, correcting the brightness of the stitched frame is also implemented to achieve a higher quality of final output frame. The performed subjective quality evaluation results using 10 neutral viewers confirm that the proposed solution achieves high performance in terms of the quality of the output image. However, the results related to the measured execution time of the proposed solution show that it cannot achieve a real-time performance in its current form when implemented on real ADAS board. Therefore, for the proposed solution the intention is to use the Vehicle-to-Infrastructure (V2I) communication and remote data processing center which should process more demanding tasks of the solution.
