A Target Detection Software Of Side Scan Sonar Based On ReWorks Operating System

As mankind explores the deepening of the ocean,how to obtain underwater information more effectively and accurately is an important issue currently facing.Underwater target detection is an important part of it.With the development of sonar technology,the underwater target detection technology continues to make breakthroughs.It is imperative to develop underwater target detection system based on intelligent underwater robot as sonar carrier.Therefore,it is of great importance to design a real-time underwater exploration software based on embedded operating system.In this paper,Seaking DST side scan sonar is designed based on ReWorks embedded real-time operating system underwater target detection software.The software PC/104 board as hardware development platform to scan sonar underwater sounding sensor,the entire system equipped with intelligent underwater robot platform to perform underwater target detection tasks.In the system design,the control side scan sonar acquisition and detection data,storage and processing of detection data,with ReWorks multi-tasking environment to build the framework of the entire system,including the creation of storage files,configure the communication mode,write and initialize sonar instructions,Sonar control and coordination of various sub-tasks,including the implementation of the system start-up,shut down,adjust sonar operating parameters,side scan sonar as a sensor in accordance with the control instructions to perform scanning and scan data back to the PC/104 processor;When the data is processed,the image data received by the control module is decoded,detects the target by means of image processing,and posts the target information to the middleware platform of the robot system for use by other modules of the robot.When detecting the target,this paper first analyzes the imaging features of side-scan sonar,and then designs the image processing algorithm around its imaging features.First,the sonar original data is homing,and then the image to be processed Image,and then the image denoising and enhancement,on the basis of the two compared to the design of the segmentation method,the final choice of a more accurate and reasonable method to complete the target segmentation and interpretation.The software can be based on the side-scan sonar work environment and user needs to adjust the sonar's operating parameters to achieve real-time underwater target detection.
