Abstract:

To solve the problems of limited field of view and information deficiency in traditional underwater imaging，and to expand the effective visual range of the real underwater environment to provide a new perspective for subsequent research and to explore the development direction of technology，a review research method is adopted in this paper. Based on the technical implementation path，the underwater image field-of-view（FOV）enhancement is divided into two categories：underwater fisheye image correction and underwater image stitching. A systematic review and in-depth analysis of the principles，system composition and existing achievements of the two types of technologies are conducted from the perspectives of methodology and system architecture. The core contents and system architectures of the two types of technologies are clarified. The existing achievements are analyzed. Then，the image space extension and detail restoration are optimized to make up for the shortcomings of traditional underwater imaging. At the same time，the key challenges in current technological development are discussed. In summary， underwater image FOV enhancement technology，as an emerging technology that integrates image processing algorithms and underwater scene characteristics，can alleviate the problem of traditional underwater imaging FOV limitation，has significant application value. In addition，the key challenges of underwater image FOV are discussed and the potential directions for its future development are explored.
