  • Many problems need to be solved before vision systems can actually be applied in industry, such as the precision of the kinematics model of the robot control algorithm based on visual information, active compensation of the camera's focal length and orientation during the movement of the robot, and understanding the mapping of the physical 3-D space into 2-D camera coordinates. An algorithm is proposed to enable robot to move actively even if the relative positions between the camera and the robot is unknown. To solve the correction problem, this study proposes vision system model with six camera parameters. To develop the robot vision control algorithm, the N-R and EKF methods are applied to the vision system model. Finally, the position accuracy and processing time of the two algorithms developed based based on the EKF and the N-R methods are compared experimentally by making the robot perform slender bar placement task.

  • In this paper, satellite communication based video surveillance system that consisted of ultra-small aperture terminals with small-size smart vision sensor is proposed. The events such as forest fire, smoke, intruder movement are detected automatically in field and false alarms are minimized by using intelligent and high-reliable video analysis algorithms. The smart vision sensor is necessary to achieve high-confidence, high hardware endurance, seamless communication and easy maintenance requirements. To satisfy these requirements, real-time digital signal processor, camera module and satellite transceiver are integrated as a smart vision sensor-based ultra-small aperture terminal. Also, high-performance video analysis and image coding algorithms are embedded. The video analysis functions and performances were verified and confirmed practicality through computer simulation and vision sensor prototype test.

  • Objectives : This study is a random-controlled post-design for confirmation of headache degree, quality of life, and satisfaction to therapeutical effect on chronic headache adults after management of non-medicinal treatment (acupuncture therapy and stellate ganglion block therapy). Methods : 51 clinical experiment participants were gathered and through a questioutaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified in to two groups, acupuncture group (AT group, n=28) and stellate ganglion block group (SGB group, n=23). Treatment was applied 2 times a weeks for 4 weeks. The effects of both groups were analyzed using VAS scores, BPI (Brief Pain Inventory) and the satisfaction degree to the therapy. Results : 1. The recognized score of the headache of AT group and SGB group was reduced indicating the degree of the headache was released. 2. The recognition at damage to the quality of life was reduced post therapy of AT group and SGB group, in which general activity, mood, enjoyment of life, personal relationship, and sleeping showed significant improvement of life quality, 3. The satisfaction degree to the therapy showed lower score than expectation to it in AT group and SGB group, however, it was not significant. Conclusions : The results showed that the four-week non-medicinal treatment (AT and SGB) in chronic headache patients was effective for reducing headache and releasing its damage in daily life, however, no difference in superiority was found. Therefore, non-medicinal treatment (AT therapy and SGB) could be utilized in chronic headache patients.

  • Purpose: The purpose of this case study is to study effect of the vision therapy on a recurrent intermittent exotropia patient before and after surgical correction. Methods: The vision therapy observation included both before and after the surgical correction of intermittent exotropia patients who had binocular vision disorder without opthalmic diseases. Results: According to the results, vision therapy method showed improvement, both case before and after the surgical correction of intermittent exotropia patients. Conclusions: Therefore we suggest that vision therapy is an effective and alternative method for intermittent exotropia patients.

  • 컴퓨터 비젼은 많은 계산을 요구하는 작업으로 구조적인 계산작업(low-level vision)과 비구조적 계산작업(high-level vision)을 가지고 실시간 처리를 요구한다. 이러한 점에서 비젼 작업의 병렬처리와 그것들의 구현에 대한 스케쥴링 schemes이 본 논문에서 중요시 된다. 그리고 PVM이 동작하는 저가의 네트워크로 연결된 워크스테이션 클러스터상에서 구현될 알고리즘을 구현하고 제안된 아이디어는 실용적인 예 (eye location from image sequence)를 들어서 보였다. 차세대의 멀티미디어 환경은 이러한 고성능의 컴퓨팅 플랫폼을 사용하리라 기대된다.

  • 1.개요 반도체 기술의 발전으로 에너지 효율이 높고 반영구적인 LED의 개발과 사용이 늘어나고 있는 추세이며, LED 관련 시장도 확대되고 있다. LED 생산에 따른 LED검사 시스템이 필수적인데도 아직 생산 현장에서는 목시검사에 의존하고 있으며, 시스템의 개발은 아직 미비한 상태이다. 몇몇의 비젼 검사관련 업체에서 비젼시스템을 이용한 LED 검사 시스템을 개발하였고, 그 밖에 논문에서 LED 검사 시스템을 개발하고 연구한 바가 있으나, 기존의 LED검사 시스뎀은 전원을 넣어 실제 LED발광 이미지에 대한 검사를 하는 것이 아니라 꺼진 상태에서의 LED 형상에 대한 검사 시스템이다.(중략)
