全景立体视觉在海上报靶中的应用

Application of Panorama Stereo Vision on Maritime Target Scoring

针对海上实弹训练自动报靶需要检测实弹和离靶中心的距离,提出一种基于双目全方位视觉传感器(ODVS)立体全景视觉测量方法,采用具有平均角分辨率ODVS的设计,将2个同样参数的ODVS以背靠背的方式合成为一个双目ODVS,利用平均角分辨率的特性,并在视频信息获取、加工上均采用高斯球面坐标,实现了一种新型的快速全方位立体图像匹配测距算法。实验结果表明,本文所设计的双目ODVS测量装置能够较准确地估算出空间物点离测量点的距离。

For the requirements of the target scoring in the maritime live practice,the distance missing the target should be measured. A new visual ranging method based on a binocular omni-directional vision sensor （ ODVS） is presented in this paper. It consists of two ODVSs with the same parameters in back-toback manner. Then,a new fast feature points matching and distance measuring algorithms is proposed by using Gaussian coordinates in the video data capturing,processing and presentation. The experiment results show that the binocular ODVS proposed in this paper can accurately measure the target point in three-dimensional space.
