船舶轮廓图像三维重构技术研究

Research on three-dimensional reconstruction of ship contour image

传统三维造型技术所得的三维坐标精准度差,为了解决这个问题,提出一种新的船舶轮廓图像三维重构技术。先提取船舶轮廓线,在处理船舶轮廓图像数据,以实现重构的完整性,在此基础上,采用零均值归一化算法,匹配船舶轮廓图像特征点,在建立粗匹配关系后,获取船舶轮廓三维点坐标,实现船舶轮廓图像三维重构,由此,完成船舶轮廓图像三维重构技术的设计。最后,在数据库中随机选取7组立体匹配对应图像点,对比2种方法的精准度,实验结果表明,所提方法精准度更高。

In order to solve the problem of poor accuracy of three-dimensional coordinates obtained by traditional three-dimensional modeling technology,a new three-dimensional reconstruction technology of ship contour image is proposed.Firstly,the ship contour is extracted and the image data of the ship contour are processed to realize the integrity of the reconstruction.On this basis,the zero-mean normalization algorithm is used to match the feature points of the ship contour image.After establishing the rough matching relationship,the coordinates of the three-dimensional points of the ship contour are obtained to realize the three-dimensional reconstruction of the ship contour image.Design of three-dimensional reconstruction technology for ship contour image.Finally,seven groups of stereo matching corresponding image points are randomly selected in the database,and the accuracy of the two methods is compared.The experimental results show that the proposed method is more accurate.
