A Method for Distance Estimation Using Intra-frame Optical Flow with an Interlace Camera

Recently, there are many researches on location estimation using optical flow, which is a well-known distance estimation method without any infrastructure. However, since the calculation of optical flow needs high computational power, it cannot adapt to highspeed movement. Therefore, in this paper, we propose intra-frame optical flow, which is a new distance estimation method using an interlace camera. It can estimate the 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 evaluation result confirmed the effectiveness of our method.
