人工智能论文:自己动手单相机3D指针输入设备(Do-It-Yourself Single Camera 3D Pointer Input Device)我们提出了一种用于单摄像机3D重建或人机界面3D输入的新算法,该算法基于对具有彩色条带图案的细长物体(例如笔)的精确跟踪。为了配置系统,用户只提供一个带有手工指针的标记图像,其彩色带的测量值以及相机的针孔投影矩阵。其他系统的成本和复杂性要高得多,需要多个摄像机,立体摄像机和带传感器和指示灯的指针的组合。我们不再依赖来自多个设备的信息,而是更仔细地检查我们的单个视图,在存在遮挡和干扰物体的情况下集成几何和外观约束,以便在指针上探测已知几何体的对象。我们展示了可接受的3D定位精度。
We present a new algorithm for single camera 3D reconstruction, or 3D inputfor human-computer interfaces, based on precise tracking of an elongatedobject, such as a pen, having a pattern of colored bands.To configure thesystem, the user provides no more than one labelled image of a handmadepointer, measurements of its colored bands, and the camera's pinhole projectionmatrix.Other systems are of much higher cost and complexity, requiringcombinations of multiple cameras, stereocameras, and pointers with sensors andlights.Instead of relying on information from multiple devices, we examine oursingle view more closely, integrating geometric and appearance constraints torobustly track the pointer in the presence of occlusion and distractor objects.By probing objects of known geometry with the pointer, we demonstrateacceptable accuracy of 3D localization.人工智能论文:自己动手单相机3D指针输入设备(Do-It-Yourself Single Camera 3D Pointer Input Device) L84mx8SAM4qqS88B.jpg
