。在单幅影像中,首

先将平行线分成分别平行于X 、Y、Z 坐标轴线的“三组”平行线,然后利用间接平差,求得它们的灭点X ∞、Y∞、Z ∞

进而求取影像的内方位元素x0 、y0 、f 与三个角元素φ、ω、κ。并在假定房屋长度为L 基础上,同时解求影像的摄站

坐标XS 、YS 、ZS 与房屋的宽度W、高度H, 从而实现房屋的三维重建。-. In the single image, were first divided into parallel lines parallel to the X, Y, Z coordinate axes of the " three"　parallel lines, then use the indirect adjustment, and seek their vanishing point X ∞, Y ∞, Z ∞　and then strike orientation elements within the image x0, y0, f and the three diagonal elements φ, ω, κ. And housing length L is assumed, based on images taken at the same time Solutions of station coordinates XS, YS, ZS and the width of Housing W, height H, in order to achieve three-dimensional reconstruction of housing.
