摘要
针对三维重建中空间点重建的问题,提出了一种以三角形重心作为约束条件的三维空间点精确欧氏重建算法。该方法以多幅图像间的对应关系会给出空间点更稳定的估计为依据,用3幅图像重建空间点,相对于传统的仅用两幅图像进行重建空间点的方法精度高,算法稳定性好。此外还可以扩展到多幅图像的重建中,通过实验与传统算法对比,表明了该算法的精准性和稳定性。
An accurate linear triangulation algorithm based on triangle center of gravity is proposed. Generally speaking the use of multiple images of the corresponding space will be given for a more stable basis for the estimates. Compared with traditional method, this algorithm uses three images to reconstruction. Which ensure that the results have high precision and stability. In addition, the method can expand to multiple images in the reconstruction. Experimental results of real images and comparisons with traditional method demonstrate its accuracy and stability.
