타임랩스 동영상 제작을 위한 촬영 이미지의 수직 변이 흔들림 보정

Abstract

In generally, time-lapse Images contains severe shaking phenomena according to the long time shooting period. Time-lapse videos were composed of multitude shooting image list and easily contained several shooting noise. The image shaking problems are based on the trembling movement of the camera supporting pore, strong wind, and so on. In this paper, we proposed a new image processing algorithm to solve the shaking problems of time-lapse video. Our algorithm is designed based on simple computation logic and comparison rules. For the reasons, our proposed algorithm is particularly appropriate for time-lapse photography. The algorithm was consisted of three steps. In the first step, we classified the image shaking type obtained from time-lapse video. In the second step, we computed the shaking degree values of input image list. Last, we reformed the all frames of time-lapse video to the new one according to the computed shaking values of the previous steps. we installed a remote camera shooting system for the stabilization experimental of time-lapse video. In results, we could confirm that our proposed algorithm could correct the shaking problem of time-lapse video. And we could obtain the experimental data that our proposed program was more efficient for vertical movement transition and rotation movement of shooting images. In the time measuring simulation we can confirmed that our program is more applicable to the area of real-time timelapse video photography.
