摘　　要：传统三维图像重建方法的重建效果较差、重建耗时较长。为解决上述问题,提出基于绝对二次曲线像的三维图像重建方法。根据多线程调度方法构建三维图像重建框架,将图像重建工作分为三个部分,分别为图像导入显示,预处理和分层重建。引入中值滤波方法对图像进行滤波,并使用Canny算子对图像进行分割。在重建过程中,计算无限平面单应矩阵以实现仿射重建,并计算绝对二次曲线像以进一步执行欧式重构,实现三维图像的分层重建。仿真结果表明,设计方法的重建效果好,重建时间短,应用性较好。In this paper,a three-dimension image reconstruction method based on the absolute conic image is put forward for improving the reconstruction effect of the three-dimension image and shortening the reconstruction time.The multithreading scheduling method was introduced to construct a three-dimension image reconstruction framework.Image reconstruction was divided into image import display,preprocessing,and hierarchical reconstruction.According to the median filtering method,the image was filtered.The Canny operator was used to segment the image.During the reconstruction,the homography matrix of the infinite plane was calculated to realize affine reconstruction.The absolute conic image was calculated to perform Euclidean reconstruction,realizing the hierarchical reconstruction of the three-dimension image.The simulation results show that the method has an excellent reconstruction effect,reduced reconstruction time,and excellent applicability.
