    • An apparatus includes a single camera and a computing terminal, and in the computing terminal, a storage means thereof stores, internal orientation parameters of the camera and actual coordinates of three feature points of a measured object, a data transfer means loads a camera image containing three feature points within a camera field of view, and a computing means performs, on camera view coordinates of the feature points in the loaded image, correction, based on the internal orientation parameters, of distortion in the image, calculates, from the camera view coordinates and the actual coordinates of the distortion-corrected feature points, a camera position and angle in a coordinate system based on the measured object during image capture, and calculates three-dimensional coordinates of the feature points in a camera-based coordinate system using a coordinate transformation with which the calculated camera position and angle during image capture are a reference position and angle.
    • 一种装置包括单个照相机和计算终端,并且在计算终端中,存储装置存储照相机的内部取向参数和测量对象的三个特征点的实际坐标,数据传送装置加载包含 相机视野内的三个特征点,并且计算装置在加载的图像中的特征点的相机视图坐标上执行基于图像中的失真的内部取向参数的校正,从相机视图 坐标以及在图像拍摄期间基于测量对象的坐标系中的相机位置和角度的失真校正特征点的实际坐标,并且使用基于相机的坐标系中的特征点的三维坐标来计算 坐标变换,在拍摄期间计算出的相机位置和角度是参考位置和角度。
