摘要：
The invention relates to a method for printing a digital image on a media object lying on a flatbed surface of a printer, the printer comprising a print head for ejecting recording material on the media object, a camera system connected to the control unit and positioned above the flatbed surface, and a control unit for storing a digital image and controlling the printing of the digital image on the media object, the media object having a contour as seen from a point of view of the camera system towards the flatbed surface, a first point having a position on the contour at a particular height with respect to the flatbed surface, and a second point being one of a point of normal projection of the first point on the flatbed surface and a point having another position on the contour than the first point, the second point being at the same height as the particular height of the first point, and the control unit storing a distance between the first point and the second point, the method comprising the steps of capturing a camera image of the flatbed surface by means of the camera system,determining a first image position in the camera image corresponding to the first point,determining a second image position in the camera image corresponding to the second point, deriving an actual position of the first point by means of the position of the camera system, the first image position, the second image position and the stored distance, and printing the digital image on the media object by ejecting recording material on the media object while taking into account the derived actual position of the first point on the flatbed surface.
摘要（中）：
本发明涉及一种用于在位于打印机的平板表面上的介质物体上打印数字图像的方法，该打印机包括用于将记录材料喷射在介质物体上的打印头，连接到控制单元并位于其上的相机系统 平板表面，以及用于存储数字图像并控制数字图像在媒体对象上的打印的控制单元，媒体对象具有从相机系统的角度朝向平板表面观察的轮廓;第一 具有在相对于平板表面的特定高度处的轮廓上的位置的点，以及第二点是平坦表面上的第一点的正常投影点和在轮廓上具有比第一点更靠前的另一位置的点之一 点，第二点与第一点的特定高度处于相同的高度，并且控制单元存储第一点和第二点之间的距离，方法com 通过相机系统来估计拍摄平板表面的相机图像的步骤，确定与第一点对应的相机图像中的第一图像位置，确定对应于第二点的相机图像中的第二图像位置，导出 通过摄像机系统的位置，第一图像位置，第二图像位置和存储距离的第一点的实际位置，并且通过在拍摄时将媒体对象上的记录材料喷射在媒体对象上来打印数字图像 考虑到平板表面上第一个点的派生实际位置。
