Abstract：Sea water temperature is a physical quantity that represents the thermal state of the ocean. Depending on the state of the ocean thermal budget and time, the ocean temperature field will periodically or irregularly change with time. Current research on ocean temperature fields is mainly focused on marine fishing, aquaculture, etc., or research on specific sampling and reconstruction methods of sea temperature. From the perspective of the practical application of underwater vehicle equipment, this paper studies the display method of ocean temperature field data. Compared with the current device that displays the temperature field information change pattern by curve values, the three-dimensional visualization method can more intuitively and effectively describe and describe the current state of the temperature field environment in the sea area, and improve the commander's understanding and application of the temperature field as a whole Making tactical decisions provides reliable technical support, so it has broad prospects in practical engineering equipment applications. This paper analyzes the seawater temperature field data characteristics and sampling methods, uses ray projection volume rendering method to realize three-dimensional display of the ocean temperature field, and encodes data classification, coordinate conversion, and resampling specific processes.
