Measure the surface of the projection along the Z axis

Measure synthesis :

Measure Type	Measure Unit Type	Parameter Type	Result Type	Shape Requirements
Geometry 3d	None	None	Value (ipsdk::ipUInt64)	Row Intersections

See Shape measurement for additional information on these pictograms

Measure Type :

This is a geometry 3d measure

• it use shape 3d data to compute a result
• it optionally can use dependencies to other measures to compute a result (see Measure Dependencies section)

This measure can only be used in 3d case

Measure Unit Type:

Measure SurfaceProjectionZ is not associated to any unit [ipsdk::shape::analysis::eMsrUnitFormat::eMUF_NoUnit]

Measure Parameter Type :

Measure SurfaceProjectionZ has no parameters

Measure Result Type :

Measure SurfaceProjectionZ is associated to ipsdk::shape::analysis::ValueMeasureResult<ipsdk::ipUInt64> results

Measure Shape Requirements :

Measure SurfaceProjectionZ requires row intersections from shape data

Measure Dependencies :

Measure SurfaceProjectionZ has no dependency

Note

See Shape Analysis 3d for more information on general shape 3d analysis and measurement usage.

Example of Python code :

Generic example in 3d case :

import PyIPSDK
import PyIPSDK.IPSDKIPLShapeAnalysis as shapeanalysis

    # Create the infoset
    inMeasureInfoSet3d = PyIPSDK.createMeasureInfoSet3d()
    PyIPSDK.createMeasureInfo(inMeasureInfoSet3d, "SurfaceProjectionZMsr")
    
    #Perform the analysis
    outMeasureSet = shapeanalysis.labelAnalysis3d(inGreyImg, inLabelImg, inMeasureInfoSet3d)
    
    # save results to csv format
    PyIPSDK.saveCsvMeasureFile(os.path.join(tmpPath,  "shape_analysis_results.csv"), outMeasureSet)
    
    # retrieve measure results
    outMsr = outMeasureSet.getMeasure("SurfaceProjectionZMsr")
    
    # retrieve measure values
    outMsrValues = outMsr.getMeasureResult().getColl(0)
    print("First label measurement equal " + str(outMsrValues[1]))
