Design of Hand-held 3 D Sonar Real-time Imaging System
摘要
Abstract
For traditional 3D sonar imaging system has the problems of low integration and poor real-time,this paper proposes a design for imaging system of real-time hand-held 3D sonar, which uses DM8127 to realize sonar image processing. To build highly accurate and real-time 3D modeling,this system uses the following methods:pre-generation of coordinate conversion array,grid construction with self-adaptive threshold,and parallel processing design,and 3D sonar image rending and display with OpenGL ES 2 . 0 . Experimental results show that this system can clearly display the underwater target topography,and the image processing speed can reach up to 25 frames per second.关键词
