基于摄影图像的三维信息提取技术研究

Research on the technology of 3D information extracting based on photograph images

通过摄影成像的坐标系统与三维坐标计算方法的研究 ,应用“特征点选取 ,多角度摄影 ,对应点匹配”图象测试模型特征点标记的匹配法 ,给出了在桨叶型值点精度测试中的试验结果 。

Research on reference frame and 3D coordinate based on photograph images is conducted. By applying 'characteristic point selecting, multiple angle picturing and corresponding point matching' method, primary result was given to calculate the precision of mould value of the blade. Precision and sensitivity about testing blade stress image were analyzed.
