ii+21p.: Illus.; 21 x 28 cm The research has been performed to investigate the use of images of the structure to assess its condition off-site. The research has concentrated on two main areas: image collection and image analysis. The image collection work has investigated the practical issues involved in imaging structures. Such issues include image resolution, lighting, removal of parallax, location referencing of individual images and the development of prototype collection system. The prototype system makes use of distance measured lasers and theodolites to determine the position of each image on the structure, and relative to any other image, making it easy to know precisely which part of the structure are affected by any particular defect. The image anallysis work has attempted to segment the images so that the defects or features present on the structure can be highlighted and classified. The segmentation work has made use of a number of image processing techniques including wavelet analysis and has achieved promosing results to date.
