The Master-Slave camera that composed of a fish-eye panoramic camera and a PTZ dome camera has been applied in many fields. Since the fish-eye panoramic camera's incline towards the gravity direction in Master-Slave camera system, the captured panoramic image has obvious horizontal distortion. In order to correct this particular type of distortion, a distortion correction method is proposed based...
A master-slave visual surveillance system is composed of one fish-eye panoramic camera and one dynamic pan-tilt-zoom (PTZ) dome camera. In order to make PTZ dome camera zoom into all targets of interest in panoramic image, the fish-eye panoramic camera is fixed inclining towards the gravity direction, which may cause more obvious distortion. This paper proposed a novel method for the distortion correction...
This paper presents a novel embedded real-time fisheye image distortion correction algorithm with application in IP network camera. A fast and simple distortion correction method is introduced based on Midpoint Circle Algorithm (MCA) which aims to determine the pixel positions along a circle circumference based on incremental calculation of decision parameters. Although only the vertical is rectilinearised,...
This paper presents a new real-time fish-eye distortion correction algorithm based on Midpoint Circle Algorithm with application in IP network camera. In particular, our method is no need of a planar checkerboard, iterative fitting of model parameters, complex computation, or traditional lookup table. Hence, our algorithm is very suitable for embedded camera platform without any extra hardware resources.
