1) parallel segments
平行线段
1.
1)If the length ratio of the two parallel segments is known,then from its projections across n images,a)2(n-1)quadratic constraint equations on camera internal parameters can be obtained;b)(5n-6)constraint equations can be obtained if additionally the epipoles across n images are known,among which 3(n-1)are quadratic,(n-2)third degree,and(n-1)fourth degree.

补充资料：平行线等分线段定理
如果一组平行线在一条直线上截得的线段 相等，那么在其他直线上截得的线段也相等
