The Research On Somatosensory Visual Tele-presence And Tele-operation Technology Of USV

In recent years, a growing number of unmanned equipment has been used in the areas such as military, rescue and detection, and achieved great results. Today, automation developed greatly, the automation of USV has been increasing, the USV can automatically detect obstacles and dangers. In investigation, maritime search and rescue, inland waterway and harbor patrol tasks, manual R/C model will play out better results. This paper attempts to study the USV Somatosensory Visual Tele-presence and Tele-operation, design a convenient,in line with the human-machine-environment system engineering power control system of USV, and to counter the large communication bandwidth usage of video, design a somatosensory visual telepresence system to solve the communication bandwidth problem,and this system can also provide a real operating environment to control the USV.This paper first introduced the background, purpose and significance of the topic and analyzed the development history and research progress of human-machine-environment system engineering , face recognition technology and video coding both at home and abroad.Firstly remote control system and somatosensory-vision telepresence system need an USV, as an application platform. After analyzing the function requirements of USV, verify the overall function, and then choose and layout onboard device.According to "Small craft engin-driven-Field of vision from helm position",analysis and layout the video camera emphasisly. Make the plan that focused on Tele-operation system and somatosensory visual telepresence system of USV .According the human-machine-environment system engineering, do the objectives established and functional objectives analysis of USV console by design deployment methodology. After reading the handbook of outboard motor and doing the necessary measurement, design Tele-operation system that using USB control stick control the outboard motor through control interface and circuit.After research the basic principles and basic methods of face recognition, and serve as a basis for structured classifiers for face recognition, and then tested the performance of classifiers for face recognition, through the result analysis the factors that affecting the accuracy of face recognition. According the SDK of video coding device, designed the somatosensory visual telepresence system, programmed the image decoding and display program by MFC and combination classifier that constructed for face recognition, eventually forming somatosensory visual telepresence system.After designed Tele-operation system and somatosensory visual telepresence system, test the performance of them. In Tele-operation system check all module of outboard motor control circuit and control interface in power system,then test the throttle, shift and lifting operation. The results show that the system can improve the operate the USV conveniently. In somatosensory visual telepresence system, After testing the system performance, measure the amount of image data and comparison with conventional imaging systems.the result has showed that somatosensory visual telepresence system can significantly save the communication bandwidth.
