    • Images of a reference object for detecting each camera position are captured by cameras 14, 16 and the relative position between the cameras 14 and 16 is obtained by using the captured images. Then, a target 18 is placed on a turntable 10 onto which reference marks 10a for detecting position are formed, and while the turntable 10 is rotated, images are captured by the cameras 14 and 16. Based on the reference marks 10a on the turntable 10, the positional relationship between the camera 14 and the target 18 is determined, and, based on the relative position of the cameras 14 and 16, the positional relationship between the target 18 and the camera 16 is determined. A three-dimensional model of the target is produced based on the images captured by the cameras 14 and 16. In this manner, a target of relatively large size is easily three-dimensionally modeled.
    • 用于检测每个摄像机位置的参考对象的图像由摄像机14,16捕获,并且通过使用所捕获的图像来获得照相机14和16之间的相对位置。 然后,将目标18放置在转台10上,在其上形成用于检测位置的参考标记10a,并且当转台10旋转时,照相机14和16捕获图像。基于转台10上的参考标记10a 确定摄像机14与目标18之间的位置关系,并且根据照相机14和16的相对位置确定目标18和照相机16之间的位置关系。 基于由照相机14和16捕获的图像来产生目标的三维模型。以这种方式,相对较大尺寸的目标容易地被三维建模。
