基于自由视角测量的三维拼接大大提高了测量的便捷性，为了提高视角间三维映射的稳健性，提出了一种改进的高稳定映射拼接方法。根据图像间匹配的特征点实现视角重合，利用结构光相位信息完成特征点三维映射和空间定位。针对特征点相位缺失无法重建的普遍问题，提出利用邻域点插值恢复特征点方法，虚拟重建视角间有效映射点，通过四元数法实现视角间点云的刚性变换和拼接。实验表明，相较传统的方法，该方法平均能将有效特征点数量提升20%，有效提高了映射拼接的稳定性。

The registration for free viewpoint measurement highly improved the efficiency of three-dimensional measurement, in order to improve the robustness of three-dimensional mapping between viewpoints, a modified method for mapping stitching with high stability is proposed. The viewpoints is coincided via image features. Spatial points are calculated through the phase positions. Aiming at those image features without phase positions, the interpositions of adjacent points are used to take the place of these points, so that effective mapping points between different viewpoints are virtually reconstructed. The rigid transformation is calculated by using unit quaternions. Experimental results show that this method can improve the number of the feature points by 20 percent and the robustness of mapping stitching.
