Abstract

An unattended recording system based on smartphone based image image tracking is rapidly developing. Among the existing products, a system that automatically tracks and rotates the object to be photographed using an infrared signal is very expensive for general users. Therefore, this paper proposes a mobile unattended recording system that enables automatic recording by anyone who uses a smartphone. The system consists of a commercial mobile camera, a servomotor that moves the camera from side to side, a microcontroller to control the motor, and a commercial wireless Bluetooth Earset for video audio input. In this paper, we designed a system that enables unattended recording through image tracking using smartphone.

최근 스마트폰 기반의 영상 이미지 추적을 통한 무인 녹화 시스템은 급속히 발전하고 있다. 기존의 제품 중 적외선 신호를 이용하여 촬영 대상을 자동으로 추적 및 회전하여 녹화하는 시스템은 일반 사용자가 사용하기에는 매우 고가이다. 따라서 본 논문에서는 스마트폰을 사용하는 사용자라면 누구나 자동 녹화가 가능한 모바일용 무인 녹화 시스템을 제안한다. 본 시스템은 상용 Mobile 카메라, 좌우로 카메라를 움직이는 서보모터(Servo Motor), 모터를 제어하는 마이크로 컨트롤러 그리고 동영상 오디오 입력을 담당할 상용 무선 블루투스 이어셋(Wireless Bluetooth Earset)으로 구성된다. 본 논문에서는 스마트 폰을 이용하여 영상 추적을 통해 무인 녹화가 가능한 시스템을 설계하였다.
