Abstract: In order to obtain laboratory wave data through non-contact means, this article explores various wave height field monitoring technologies, compares the application effects of different image feature extraction and matching algorithms based on binocular vision, conducts experiments in a multi-functional towing tank, and locates and matches image feature points based on the dynamic image data captured by binocular cameras, achieving high-precision reconstruction of the three-dimensional shape of waves. Through the evaluation of the practical application effects of different feature extraction and matching algorithms, the experimental basis and technical support for improving the accuracy and applicability of wave monitoring technology are provided.
