  • With the recent increase in YouTube content, many YouTubers are shooting with a handheld camera. Audiences are increasingly accustomed to the movement of handheld cameras. As the camera moves faster than the camera movement of the old movies, and the camera moves splendidly to the music of the music video, the camera movement in CG animation is also needed to change. The handheld Steadicam creates a natural camera movement by compensating so that the screen does not vibrate significantly even when the vibration is large and by minimizing rotation. In order to implement such camera movement, we tried to make a handheld Steadicam using nParticle simulation of Maya software and apply it to the scene to verify whether it is possible to implement the necessary natural and various movement.

  • Free vibrations of strings due to initial conditions have been analyzed by the conventional mode summation method, and the nondimensionalized displacements and velocities have been derived in the form of infinite series. The results show wave propagating phenomena and confirmed by experiments using the high speed camera. Other physical characteristics have been discussed and examined with help of waveform solutions.

  • In this study, the performance of a digital pile rebounding and penetration monitoring system (DPRMS) is evaluated and the measurement precision of the DPRMS is improved. The DPRMS is a high speed line-scanning camera system to measure the rebound and penetration of a pile in a construction work. A main problem in the DPRMS is a measurement error, which is caused by a shock or vibration due to a hammer impact. The measurement error is investigated by analyzing vibration signals of the DPRMS during the impact. Moreover, the frequency response functions of the DPRMS are also analyzed. As a result, it is found that the tripod height has an influence on the DPRMS performance and a shorter tripod is better. One more founding in this study is that the DPRMS should be placed with a appropriate distance from a pile for improving the measurement precision.

  • 인터레이스 방식의 카메라가로부터 사진을 촬영시, 카메라가 움직인다면, 짝수와 홀수라인의 두 영상의 불인치인 블러가 발생한다. 본 논문은 인터레이스 방식의 카메라의 떨림에 의한 짝수와 홀수라인 영상간의 불일치를 제거하는 알고리즘을 제안하였다. 블러된 원 영상을 짝수라인과 홀수라인 영상으로 분리한다. 분리된 각 영상을 보간법을 이용하여 원 영상 크기의 영상을 생성한다. 만약 보간된 영상간의 큰 차이가 발생하면, 사진 촬영시 카메라가 움직인 경우이다 이 경우에는, 특징점 추출 및 정합, sub-pixel정합, 오류 정합된 광류제거, 영상모자이크를 통하여 불리된 두 영상으로부터 블러가 제거된 영상을 취득하는 것이다. 본 논문은 제안한 알고리즘이 카메라의 다양한 움직임의 영향으로 블러된 영상에서 선명한 영상을 생성 할 수 있음을 보였다.
