The application cnetstats has the ability to generate statistics and apply filters on a Control Network and outputs results in a specified output file in CSV format.

Overview Parameters

Description

The application cnetstats has the ability to generate Statistics and apply filters on a Control Network and the results are saved to specified output file in CSV (Comma Separated Value) format.

Application takes in as input the Control Net CNET and its corresponding images list FROMLIST. FROMLIST contains the filenames of all the images that are part of the input Control Net. When application is run it will generate a Control Net Statistics in PVL format. This is displayed in the Application Gui and also logged in the print.prt file. The Control Net Statistics are generated for all the Points in the Control Net irrespective of all the different options chosen.

Following is the Control Net Statistics format:

Group = ControlNetSummary
TotalImages = Positive Integer
ImagesInControlNet = Positive Integer
TotalPoints = Positive Integer
ValidPoints = Positive Integer
IgnoredPoints = Positive Integer
FixedPoints = Positive Integer
ConstrainedPoints = Positive Integer
FreePoints = Positive Integer
EditLockPoints = Positive Integer
TotalMeasures = Positive Integer
ValidMeasures = Positive Integer
IgnoredMeasures = Positive Integer
EditLockMeasures = Positive Integer
AvgResidual = Double
MinResidual = Double
MaxResidual = Double
MinLineResidual = Double
MaxLineResidual = Double
MinSampleResidual = Double
MaxSampleResidual = Double
MinLineShift = Double
MaxLineShift = Double
MinSampleShift = Double
MaxSampleShift = Double
AvgPixelShift = Double
MinPixelShift = Double
MaxPixelShift = Double
MinGoodnessOfFit = Double
MaxGoodnessOfFit = Double
MinEccentricity = Double
MaxEccentricity = Double
MinPixelZScore = Double
MaxPixelZScore = Double
MinConvexHullRatio = Double
MaxConvexHullRatio = Double
AvgConvexHullRatio = Double
EndGroup

Additional Statistics can be generated if required based on Images and/or Control Points into the user specified output file.

1. Image Stats provides Statistics based on Images in the Control Net. To generate Image Stats report, click on the option CREATE_IMAGE_STATS which will enable IMAGE_STATS_FILE option. Image Stats are generated in CSV format in the output file specified in the option IMAGE_STATS_FILE. It also reports images that are part of the input list but not in the Control Net. For images that are not part of the Control Net, the image stats would be zero.
Following is the Image Stats information in CSV format:

FilenameSerialNumberImageTotalPoints ImagePointsIgnoredImagePointsEditLockedImagePointsFixedImagePointsConstrainedImagePointsFree ImageConvexHullRatio

2. Point Stats provides statistics based on Control Points in the Control Net. To generate the Point Stats report, click on the CREATE_POINT_STATS option which will enable POINT_STATS_FILE option. Point Stats are generated in CSV format in the output file specified in the option POINT_STATS_FILE. Following are the information generated by this option:
PointIdPointTypePointIgnoredPointEditLockedTotalMeasures MeasuresValidMeasuresIgnoredMeasuresEditLocked

cnetstats also has the option to Filter the input ControlNet based on different Filters. To apply Filters, the FILTER option must be enabled and the Filters in PVL format must be provided in the DEFFILE. The results of the Filters will be placed in the specified output file FLATFILE in CSV format. Each Filter has its own custom report format and hence the output format is different depending on the last Filter used.
Note:The Points and Measure with EditLocks will always be filtered in irrespective of the filter settings.
The DEFFILE contains the PVL filters in the following format:

Object = Filters
Group = FilterName1
option = value
EndGroup
Group = FilterName2
option = value
EndGroup
EndObject

The DEFFILE is validated upfront before any processing to save time involved in reading a Control Net. It is important that the DEFFILE adheres to the specified format. The DEFFILE can contain as many filters as available and the application will apply the filters sequentially in the First In First Out fashion. The output of the previous Filter will be the input for the current Filter. The report generated will be based on the last Filter run on the Control Net. It should also be noted that a Filter can be defined only once in a DEFFILE that means it can be run only once during an execution of cnetstats. If the Filter needs to be run again, the application must be run again with this Filter in the DEFFILE.

In any given Filter if it requires options LessThan/GreaterThan the values will always be inclusive. For example, in measures Filter, if LessThan = 3 and GreaterThan =1, cnetstats will find all the Control Points with Control Measures >= 1 and <=3.

There are 2 kinds of Filters, Point Filters and Cube Filters.

Following are the Point Filters:
1. ResidualMagnitude
2. Id
3. Measures
4. Properties
5. Latitude Longitude Range
6. Distance
7. Measure Properties
8. Cube Names(Serial Number)
9. EditLock
10. Measures EditLock
11.Pixel Shift
12.Goodness of Fit

Following are the Cube Filters:
1. Name
2. Number of Points
3. Distance
4. Convex Hull Ratio

The Format for the output files will be in Comma Separated Value(CVS).

1. ResidualMagnitude - Filter the ControlNet by Control Point ResidualMagnitude. This Filter, filters all the Control Points which have atleast one Control Measure in the specified range. Options LessThan and GreaterThan can be combined which will be applied as a Range or used alone. These values will always be inclusive. To omit an option, it can be deleted from the group.
