Research On Single-soldier Combat Target Real-time Detection System Based On Binocular Vision

In recent years,with the development of economy and national strength,modern military equipment came into being.In the era of the rapid development of information technology,some powerful nations have begun to develop the single-soldier combat system,and have improved the attack,defense,information,comfort,weight and continued,etc.In this application background,this thesis uses the digital image processing algorithm and computer vision processing technology to perceive the regional information,position information and motion information of moving target,in order to enhance the combat ability and protection ability of individual soldier.The binocular vision experimental platform was built by using the binocular stereo vision measurement theory and detection technology,and the software system was designed and implemented.Firstly,the camera model and distortion model are expounded.Secondly,the calibration work of the camera is completed by using the Zhang Zhengyou plane calibration method,as the results,the internal and external parameters,distortion vector and relative position relationship of the binocular camera can be obtained.In addition,the semi-global block matching stereo matching algorithm is studied,and the parallax image is converted into three-dimensional coordinate information,which achieves the purpose of 3D reconstruction.Finally,the ViBe algorithm of pixel level video background modeling and foreground detection is used to detect the corrected image and obtain the region,position and motion information of the moving object.By using the software redeveloped by Dacheng camera for detecting target of single-soldier combat,the relevant experiments are carried out on binocular image acquisition,camera calibration,stereo matching and motion detection.After many experiments,this software system solution is proved to be feasible,which means that the calibration error is small,the motion detection delay is low,the correction effect is ideal,and the depth of field measurement error is controlled within 1%.The results show that this system can quickly and effectively detect the position information,regional information and motion information of moving target,and then achieve the purpose of auxiliary single-soldier combat.
