Disclosed is an image surveillance system. This system includes a fisheye camera and an image surveillance device. The fisheye camera comprises: a fisheye lens; an image sensor to capture light which has passed through the fisheye lens and converting light into an electrical analogous fisheye image; an analog/digital converter to convert an electrical analogue fisheye image signal into a digital fisheye image; an image conversion portion to convert the digital fisheye image into a panorama image; and an image transmission portion to transmit the panorama image. The image surveillance device comprises: an image receiving portion to receive the panorama image from the fisheye camera; an image restoration portion to restore the fisheye image from the received panorama image; and a distortion correction portion which corrects distortion by dewarping the restored fisheye image at a specific point in time, thereby capable of surveilling an image using the fisheye camera even with an image surveillance device having a somewhat deteriorated performance.
영상 감시 시스템이 개시된다. 이 시스템은 어안 카메라와 영상 감시 장치를 포함한다. 어안 카메라는 어안 렌즈와, 어안 렌즈를 통과한 광을 촬상하고 전기적인 아날로그 어안 영상으로 변환하는 이미지 센서와, 전기적인 아날로그 어안 영상 신호를 디지털 어안 영상으로 변환하는 아날로그/디지털 컨버터와, 디지털 어안 영상을 파노라마 영상으로 변환하는 영상 변환부, 및 파노라마 영상을 전송하는 영상 전송부를 포함한다. 영상 감시 장치는 어안 카메라로부터 파노라마 영상을 수신하는 영상 수신부와, 수신된 파노라마 영상으로부터 어안 영상을 복원하는 영상 복원부, 및 복원된 어안 영상을 특정 시점에서 디워핑(dewarping)하여 왜곡 보정하는 왜곡 보정부를 포함한다.
