Catadioptric Imaging System with a Hybrid Hyperbolic Reflector for Vehicle Around-View Monitoring

Abstract

A wide field-of-view (FOV) imaging system is essential for a vehicle around-view monitoring system to ensure the safety of driving or parking. This study presents a hybrid hyperbolic reflector for catadioptric wide FOV imaging. It is possible to observe the horizontal side scene as well as the vertical ground scene surrounding a vehicle using the hyperbolic reflector imaging system with a single camera. The image acquisition model is obtained for the hyperbolic reflector imaging system using the geometrical optics in this study. The image acquisition model is the basis of the image reconstruction algorithm to convert the side scene into a panoramic image and the ground scene into a bird’s-eye image to present it in the driver’s display. Both the horizontal panoramic image and the vertical bird’s-eye image surrounding a vehicle are helpful for driving and parking safety.
