扫描的坐标空间

By default the scanner coordinate system has its origin in the camera, the Z coordinate aims to the scene, X coordinate aims outside the scanner (to the right) and Y coordinate to the back (bottom of the scanner).

You can view this coordinate space in PhoXi Control Application after triggering the scan. There is a checkbox on on the right pane called "Axis". After you check it, move the scene and the axis will be depicted. Or you can save the point cloud and explore the coordinate space in external viewer, e.g. Meshlab, which is able to render the axis.

All point coordinates are in millimeters.

Scanner can work also in different coordinate spaces:

• Marker Coordinate space - see Scans alignment
• Robot Coordinate space - see Robot-Camera Calibration Tool
• or any custom transformation manually defined

默认情况下，扫描仪坐标系的原点位于相机中，Z坐标指向场景，X坐标指向扫描仪外部（右侧），Y坐标指向后部（扫描仪底部）。

触发扫描后，您可以在PhoXi Control Application中查看此坐标空间。在右侧窗格上有一个名为“轴”的复选框。检查后，移动场景并显示轴。或者，您可以保存点云并在外部查看器中探索坐标空间，例如Meshlab，它能够渲染轴。

所有的点坐标均以毫米为单位。

扫描仪也可以在不同的坐标空间中工作：

• 标记坐标空间 - 参见扫描对齐
• 机器人坐标空间 - 参见机器人 - 照相机校准工具
• 或手动定义的任何自定义转换
