Because it enables ultra-fast object recognition capabilities, 3-dimensional (3D) reconstruction can help to improve the reaction times of a vehicle’s advanced driver assistance system (ADAS). A key advantage of this approach is that data emanating from a smaller region of interest (RoI) can be analysed and processed. This allows the position, height and width of obstacles that would not typically be detected via conventional pattern recognition techniques to be determined, and appropriate actions taken. Through the use of advanced imaging algorithms, 3D estimation data can now be rapidly compiled on both static and moving objects. Sophisticated imaging systems employing such technology are already under development with several leading automobile manufacturers.
