    • A device and method can carry out reliable visceral 3-D input over a wide range at arbitrary measuring time intervals without being affected from electric field or temperature, with requiring small installation space. A bright spot is displayed on the display surface of a display by scanning. A photo device condenses the bright spot on the display to project the spot light onto the projection plane, thereby projecting it onto photo detectors the projection plane. A counter counts the time from the time of a vertical sync signal, and supplies its output to AND gates. A correspondence detector brings bright spot display positions on the display at multiple times into correspondence with their projection positions on the photo device in accordance to recording time. An extrinsic parameter calculator calculates the 3-D translation and rotation of the photo device with respect to the bright spot scanning surface of the display from at least three sets of the bright spot display positions and their corresponding projection positions.
    • 可以任意测量时间间隔在宽范围内进行可靠的内脏3-D输入的设备和方法,而不受电场或温度的影响,并且需要较小的安装空间。 通过扫描在显示器的显示面上显示亮点。 照片装置将亮点聚集在显示器上以将光束投影到投影平面上,从而将其投影到投影平面的光电检测器上。 计数器从垂直同步信号的时间计数时间,并将其输出提供给与门。 对应检测器根据记录时间在显示器上使亮点显示位置与照相装置上的投影位置相对应地多次显示。 外部参数计算器从至少三组亮点显示位置及其对应的投影位置计算照相装置相对于显示器的亮点扫描表面的3-D平移和旋转。
