Abstract

There has recently been much research on estimates of location using optical flow, which is a well-known for estimating distances. However, since high computational power is needed to calculate optical flow, it cannot be adapted to high-speed movement. This paper proposes an intra-frame optical flow, which is a new method of estimating distances using an interlace camera. It estimates high-speed moving objects accurately because it uses two successive images with a very short scanning interval extracted from one image captured by an interlace camera. The result obtained from evaluation confirmed the effectiveness of our method.
