Detailed Description

Stores a 3d camera constraint.

Constructor & Destructor Documentation

~CameraConstraintInterface()

virtual FLE_DLL FlowEngine::CameraConstraintInterface::~CameraConstraintInterface ( )

virtualdefault

Default virtual destructor.

Member Function Documentation

getCamera()

virtual FLE_DLL void FlowEngine::CameraConstraintInterface::getCamera ( CameraInterface &  camera ) const

pure virtual

Returns the camera associated with this constraint.

Parameters

[in,out]

camera

a valid instance of a CameraInterface object.

getPosition()

virtual FLE_DLL void FlowEngine::CameraConstraintInterface::getPosition ( Point3 &  outConstraint ) const

pure virtual

Returns the 3D constraint for this camera constraint.

Parameters

[out]

outConstraint

x-y-z constraint position in space.

getWeight()

virtual FLE_DLL void FlowEngine::CameraConstraintInterface::getWeight ( float &  outWeight ) const

pure virtual

Returns the 3D constraint weight for this camera constraint.

Parameters

[out]

outWeight

constraint weight.

setCamera()

virtual FLE_DLL void FlowEngine::CameraConstraintInterface::setCamera ( CameraInterface &  camera )

pure virtual

Changes the camera associated with this constraint.

Parameters

[in]

camera

a valid instance of a CameraInterface object.

setPosition()

virtual FLE_DLL void FlowEngine::CameraConstraintInterface::setPosition ( const Point3 &  constraint )

pure virtual

Set the 3D constraint for for this camera constraint.

Parameters

[in]

constraint

x-y-z constraint position in space.

setWeight()

virtual FLE_DLL Result FlowEngine::CameraConstraintInterface::setWeight ( float  weight )

pure virtual

Set the weight for this camera constraint.

Note

This parameter is ignored when using the constraint in the structure and motion phase, instead, it's used during bundle adjustment.

Parameters

[in]

weight

constraint weight. The valid range is (0, inf). This value should be in inverse proportion to the precision of the coordinates, following this formula: weight = 5.0 * 0.3 / cpc where cpc is the expected precision in meters. e.g. when using GPS coordinates (cpc == 10.0) then weight = 0.15 e.g. when using RTK coordinates (cpc == 0.3) then weight = 5.0

Returns

One of the following result codes:

• Result::Success – if the new constraint weight has been set successfully.
• Result::InvalidArgument – if weight is not in the valid range.
