| 摘 要： | 为研究基于单幅二维图像不标定欧氏重构三维场景的理论，解决被动视觉系统中难以解决的特征点匹配问题，文章介绍一种有效的采用伪随机编码结构光照明主动视觉技术。利用伪随机序列的窗口特性，使被编码结构光照明的场景表面每一个特征点都具有唯一的代码，可以唯一地被辨识。实验数据和重构结果验证了该编码的可行性和有效性。

| Abstract: | In order to study the theory of uncalibrated 3D Euclidean reconstruction based on simple image and solve characteristic point match problem in passive vision system, an effective active vision technique is introduced. Structured light illumination with pseudo- random code is applied to the system. Each interest point on scene surface can be identified exclusively according to window property of pseudo - random array. Data and results of reconstruction verify feasibility and effectiveness of the code. |
