# ExtractPlane3D Vision Data Access functions

This section lists the available 3D Vision Data Access functions that get values from the results of a Planes3D structure.

Note: Each of the following functions references the results of a Planes3D structure for the first parameter. Index (zero-based) determines which result 3D plane of the Planes3D structure you want to reference. If you do not specify the index, the index defaults to zero, meaning the function Functions are tools that are available in Spreadsheet for processing and analyzing acquisitions or other results. You can add functions to your Spreadsheet job to create tool chains and produce results for specific applications. returns the first plane.

Function | Description
GetNFound(Planes3D) | Returns the number of found planes.
GetNumInliers(Planes3D, [Index]) | Returns the number of inliers in the plane specified with the index number. Note: You can only use the GetNumInliers() function when you use the Robust mode, otherwise the function shows an error.
GetPlane(Planes3D, [Index]) | Returns the extracted Plane3D structure specified with the index number.
GetRectangle(Planes3D, [Index]) | Returns a Rectangle3D structure.
GetRelativeTilt(Planes3D, [Index]) | Returns the relative tilt angle of the extracted plane specified with the index number.
GetResidualsMax(Planes3D, [Index]) | Returns the maximum residual Residuals measure how far inlier points deviate from the fitted geometric model. The root-mean-squared (RMS) residual is the average distance of all inlier points from the model. The maximum residual is the largest distance among the inliers. Smaller residual values indicate a more accurate and less noisy model fit. of the specified 3D plane.
GetResidualsRMS(Planes3D, [Index]) | Returns the root mean square residual of the specified 3D plane.
GetScore(Planes3D, [Index]) | Returns the score of the extracted plane with the specified index number, as a value between 0 – 100.
