中文说明：
在本文中，我们描述了一个新颖的无标定主动立体系统，它采用编码加密过的结构光。该方法是基于一个针对消极立体系统的无标定立体技术，在该技术中，一个投影仪代替一台摄像机。它还提出了一个同步三维重建方法，提高准确性和一个简单的方法来消除一个激光指针到投影的缩放模糊性。
English Description：
In this paper, we describe a novel uncalibrated active stereo system, which uses encoded and encrypted structured light. This method is based on an uncalibrated stereo technology for passive stereo system, in which a projector replaces a camera. It also proposes a synchronous 3D reconstruction method to improve the accuracy and a simple method to eliminate the scaling ambiguity of a laser pointer to the projection
