Detailed Description

Calculates a series of statistics pertaining to a Camera.

Given a Camera pointer–or the filename of a Cube whose Camera is to be used–this class will calculate a series of statistics at initialization on the Camera. After construction, the user can retrieve statistics, compiled for every line/sample of the Camera, for the Camera's latitude, longitude, pixel resolution, sample resolution, line resolution, phase angle, emission angle, incidence angle, local solar time, meters, north azimuth, and aspect ratio.

Constructor & Destructor Documentation

◆ CameraStatistics() [1/3]

Isis::CameraStatistics::CameraStatistics	(	QString	filename,
		int	sinc,
		int	linc
	)

Constructs the Camera Statistics object from a Cube filename.

This constructor will first open the cube corresponding to the "filename" parameter, then gather statistics with the Cube's Camera. Neither the Cube nor its Camera is retained after statistics gathering has completed, but the filename used to open the Cube will be output in the "User Parameters" group of the "toPvl" method. The invoker of this constructor must also specify the sample and line increments to be used during statistics gathering.

Parameters

filename	String filename of the Cube whose Camera will be used
sinc	Sample increment for gathering statistics
linc	Line increment for gathering statistics

References Isis::Cube::camera(), and Isis::Cube::open().

◆ CameraStatistics() [2/3]

Isis::CameraStatistics::CameraStatistics	(	Camera *	cam,
		int	sinc,
		int	linc
	)

Constructs the Camera Statistics object from an already-existent Camera pointer.

Specifying sample and line increments of 1 will gather statistics on the entire area encompassed by the Camera, but higher numbers can be used to improve performance. Using this constructor–lacking a Cube filename–the "toPvl" method will not output the Cube filename associated with the Camera. If the user desires this information, there is a constructor that will take the filename purely for this purpose.

Parameters

cam	Camera pointer upon which statistics will be gathered
sinc	Sample increment for gathering statistics
linc	Line increment for gathering statistics

◆ CameraStatistics() [3/3]

Isis::CameraStatistics::CameraStatistics	(	Camera *	cam,
		int	sinc,
		int	linc,
		QString	filename
	)

Constructs the Camera Statistics object from an already-existent Camera pointer.

Specifying sample and line increments of 1 will gather statistics on the entire area encompassed by the Camera, but higher numbers can be used to improve performance. The filename provided does not serve a functional purpose during the statistics gathering process, but will report the filename used to create the Camera instance in the "User Parameters" section of the PVL output from the "toPvl" method.

Parameters

cam	Camera pointer upon which statistics will be gathered
sinc	Sample increment for gathering statistics
linc	Line increment for gathering statistics
filename	String filename of the Cube whose Camera is being used

◆ ~CameraStatistics()

Isis::CameraStatistics::~CameraStatistics ( )

virtual

Destroy this instance, deletes all the Statistics objects.

Member Function Documentation

◆ addStats()

void Isis::CameraStatistics::addStats	(	Camera *	cam,
		int &	sample,
		int &	line
	)

Add statistics data to Statistics objects if the Camera position given by the provided line and sample is looking at the surface of the target.

Parameters

cam	Camera pointer upon which statistics are being gathered
sample	Sample of the image to gather Camera information on
line	Line of the image to gather Camera information on

◆ constructKeyword()

PvlKeyword Isis::CameraStatistics::constructKeyword	(	QString	keyname,
		double	value,
		QString	unit = `""`
	)		const

Takes a name, value, and optionally units and constructs a PVL Keyword.

If the value is determined to be a "special pixel", then the string NULL will be used for the value.

Parameters

keyname	Name of keyword to generate
value	Value to write to keyword
unit	Optional units for keywords

Returns: PvlKeyword Keyword constructed from input parameters
