In this paper, we propose a distance estimation method using tilted lens optics. Our proposed method uses two input images: one is an all-in-focus image, and the other is a ground-infocus image. The method estimates a distance value for each pixel by comparing the amount of blur between the ground-in-focus image and multi-focus images that are synthesized by applying a Gaussian filter to the all-in-focus image. As our method needs only two input images and simple calculations, it is suitable for distance estimation applications that require a wide detection range and real-time processing, such as robotics and automotive tasks.

“…In the past, there have been several methods using horizontal POFs [3][4] [5]. However, these methods have disadvantages, such as the real time estimation, the acceptance of target objects that have constant texture only, the inability to estimate distance pixel by pixel, and the difficulty of lens calibration.…”
