Abstract

An underwater detection apparatus (1) includes a transmission transducer (2), a reception transducer (3), a volume data generation module (21), a group generation module (22), and an image data generation module (24). The transmission transducer (2) transmits a transmission wave. The reception transducer (3) includes a plurality of reception elements, each of them generating a reception signal based on a reflection wave of the transmission wave on an underwater target. The volume data generation module (21) generates volume data based on the reception signal, the volume data including echo intensity data at each reference position. The group generation module (22) groups the echo intensity data into a plurality of groups each having data with an echo intensity above a threshold, and where a common isosurface is generated. The image data generation module (24) sets a property of the isosurface of a first group based on a representative echo intensity.
