Embodiment Construction
[0064] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0065] The present invention is a three-dimensional visualization method of ocean water sound field based on an improved ray casting algorithm, which improves the speed of three-dimensional visualization of ocean water sound field from the principle of visualization algorithm. The method is not limited by graphics hardware and can be implemented on a common PC, and Has a faster visualization speed.
[0066] The invention specifically includes three-dimensional underwater sound field data preprocessing, resampling point coordinate calculation, resampling point interpolation calculation, data classification, and image synthesis. The specific process is as figure 1 shown, including the following steps:
[0067] Step 1: Preprocess the sound intensity propagation loss data of underwater acoustic waves obtained by the three-dimensional parabolic equ...
