M. Tech. Electronic Engineering. / The Council for Scientific and Industrial Research (CSIR) in South Africa has developed a portable Multi-Spectral Imaging Camera (MultiCam) capable of capturing images in the Visual (VI), Infra Red (IR) and Ultra Violet (UV) bands. The images obtained from the MultiCam are used to perform diagnostics on high voltage transmission networks. To provide the user with a better understanding of the scene it is necessary to fuse the images. Due to the physical placement of the detectors and the separate zoom-control of each optical channel, a spatial misalignment or geometric distortion is introduced to the images. The images must be optimally aligned and registered before any fusion can be applied. The aim of this work is to investigate methods for the automatic registration and fusion of IR and VI images acquired by the MultiCam and to develop a set of algorithms for implementation on an embedded platform that could integrate with the existing MultiCam
