| 摘 要： | 实现基于单幅二维图像不标定欧氏重构三维场景的关键技术之一是有效提取彩色伪随机编码图像特征角点。为给图像特征点匹配提供更多的样本信息，采用定位于彩色图像Harris算子探测特征角点，并动态给出角点响应的自适应阈值条件。特征点提取实验及三维欧氏重构结果证实了该方法的适用性和有效性。 |

| Abstract: | The effective feature point's extraction is one of the key technologies in uncalibrated 3D Eaclidean reconstruction based on single pseudorandom color coded image. In order to provide feature matching with more swatch information, introduces Harris's color image orientation operator to detect feature point and dynamicly gets an adaptive threshold to judge the corner point.The results of feature extraction experiment and the Euclidean 3D reconstruction confirm the applicability and effectiveness of the present method. |
