Realization of small platform 3D imaging sonar display system
Abstract:In order to meet the demand in acoustical three-dimension(3D) imaging for small platform sonar and carry out the evaluation for submarine topography,a multi-subarray amplitude-phase joint detection algorithm with a dual-core OMAP5912 chip as a core processor was proposed based on the real time realization of DSP inner core.A set of 3D display fuction library was developed with ARM inner core,and 3D reconstruction display for submarine topographic information based on LCD was realized.In addition,a man-machine interface was designed by using QT/E.The present small platform 3D imaging sonar system exhibits the stable properties during the Songhua Lake field experiment,and can effectively accomplish the pseudo-color display for the 3D topographic information of lake-floor.Moreover,the effectivity,practicality and superiority of the proposed method has been proved sufficiently.
