REAL-TIME PROCESSING SYSTEM AND METHOD FOR PHASED ARRAY THREE-DIMENSIONAL ACOUSTICS IMAGE PICKUP SONAR

摘要

A real-time processing system and method for phased array three-dimensional acoustics image pickup sonar. The system comprises: a three-dimensional sonar point data collecting module (100), a three-dimensional sonar point data uploading module (200), and a three-dimensional sonar point data real-time processing module (300) located at a PC client. The method comprises: performing two-stage FPGA signal processing, real-time electronic focusing and wave forming, so as to obtain three-dimensional sonar point data; forwarding the three-dimensional sonar point data to a PC client and setting and obtaining a command; and the PC client receiving the three-dimensional sonar point data and performing real-time processing, comprising: single-frame multi-layer real-time reconstruction, image registration and mosaicing, three-dimensional visualization, and real-time storage of the data.
