平行线约束 meaning in English

parallel line constraint

Both methods provide good performance , and the latter is better since it can give a better describing of the residual distribution of matches . in the study of camera self - calibration , firstly , based on discussion of using and the selecting of scene constraints , two new robust vanishing point estimation algorithms are presented . one is based on peransac , and the other is based on clustering
在相机自定标技术的研究中,首先,在讨论利用和选择景物约束的基础上,提出两个新的消失点估计算法:基于peransac的估计算法和基于聚类分析的估计算法,后者在估计精度上优于前者;其次,提出了综合利用空间平行线约束和相机主点位置约束的线性迭代自定标方法,提高了相机自定标的鲁棒性。
