PhoXi Scanners have the resolution of 3,2 Million points, which correspond to the resolution of the 2D sensor inside (2064x1544). For each pixel in the 2D sensor there is one computed 3D point. The accuracy of the computation for each pixel is estimated by the "confidence" value, which express the error of 3D measurement in millimeters. Please note that this value is only the estimation. The real value can be obtained only by the comparison with the gold (CAD) model.

Open the "Output Structure" tab in the Left Pane, check "ConfidenceMap" checkbox and confirm by button "Set". New tab will be added into the viewer pane. Now trigger the scan and switch the current view to ConfidenceMap. Use "Maximal value" threshold in the right pane and set it to small value (e.g. 1.00 mm). The error of measurement for each pixel is now mapped into color: points with zero error will be black, points with error above 1 mm will be white and the points with error between 0-1 will have some shade of gray.

Move the mouse pointer over the pixels to see the actual confidence value (estimated error of measurement) in the right pane.

===如何保存点云? ===
 +
要保存当前点云,请使用顶部面板中的“SavePointCloud”按钮。该文件将以选定的文件格式存储。要选择何种数据会存储在文件中,请点击“Recording options”按钮,然后点击想要文件格式旁边的“Options”按钮。

最一般的文件格式是PLY。可保存的有用数据是PointCloud,NormalMap,Texture和使用BinaryFormat。
  
== Saving the Confidence Map in the PLY ==

如果要保存有关扫描的所有信息,请使用Photoneo的Raw数据格式。
  
Open the Saving Options dialog and in the PLY options check "Confidence Map".

要自动存储每个捕获的帧,请使用“Record”按钮。点云将以“Recording Options”中设置的目录和文件格式保存。

And the information about each point will contain also the confidence value.

Explanation:
 
* Point coordinates [-49.9265 -3.09847 186.842]
 
* Point normal vector [0.359787 -0.00883223 -0.932993]
 
* Point color in RGB [15 15 15]
 
* Point color in 32bit [19]
 
* Confidence [0.0265961] - this means that the point was captured with the estimated accuracy of 0.0265961 mm
