Underwater acoustic / optical imaging system

This paper introduces an underwater acoustic / optical integrated imaging system, which individual uses the DSP core and ARM core of the OMAP3530 processor to realize the multi-subarray amplitude-phase united detection algorithm and optical camera image collection for getting the estimating the depth of the sea and the optical information of the focus area uses the ARM core to receive the GPS and other parameters from the UART and then realizes the three-dimensional acoustic imaging of the seafloor with OpenGL | ES library in PowerVR core of the OMAP3530 processor, uses the QT embedded designed human-machine interface to realize the acoustic and optical image information real-time displaying relies on the network uploading the data to the mother-ship o During the Songhua Lake experiment time the whole system run very well and had good performance. The Underwater acoustic / optical integrated 3D imaging system is suitable for underwater topography, marine salvage search and rescue, undersea resource exploration and other fields which has a wide application prospect and huge market demand.
