N2 - Underwater tubes are critical infrastructure components for city transportation. The installation and connection of immersed tubes in underwater environments require accurate localization technologies. Currently, many immersed tube localization methods rely on Global Navigation Satellite System (GNSS) based satellite towers. However, various forces such as the tube’s own weight, water pressure, etc. inevitably cause tube deformations and satellite tower to tilt, then affecting tube posture estimation. Targeting this challenge, this paper develops a novel underwater immersed tube deformation measurement algorithm, which detects tube geometric deformation based on cameras and lasers. The cameras and lasers are used to measure horizontal and vertical deformations respectively. Then, the overall geometric deformation can be obtained from the two deformations accurately. Extensive real-world experiments demonstrate that, compared to the GNSS-based satellite towers method, our proposed method significantly reduces localization errors and has been applied to the construction program of the Shenzhen-Zhongshan underwater tube tunnel.
