如何将坐标空间设置为标记空间
- Open PhoXi Control App and connect to the scanner
- In the options pane on the left, check following options in group Coordinates:
- MarkersSettings > InvertedMarkers
- RecognizeMarkers
- CoordinateSpace = MarkerSpace
- Put marker plate in the view of camera. Make sure camera sees at least four marker circles, then trigger the scan. Point cloud will be returned in coordinate system of marker plate.

如何创建物体的模型
- Put the object above the marker plate and switch the coordinate space to Marker space. You can now move the scanner to different locations, it always returns the point cloud in the same coordinate system defined by marker plate.
- Make several scans from different angles to capture the object from all sides. Save each scan to PLY file.
- Open all PLY files in 3D point cloud viewer, e.g. Meshlab or Cloud Compare, crop the desired object, use some fine alignment algorithm (ICP), merge the point clouds and polygonize it to create a surface model.
问题
- Image corrupted
- If the application does not return the scan and there is a message in the status bar "Image corrupted", make sure the angle between the scanner and marker plate is not too small and that the camera can see at least 4 marker circles.
