Member Function Documentation

frameBoundingPoly()

virtual bool ossimVideoGeometry::frameBoundingPoly ( const double &  t, ossimPolygon &  geo_poly  ) const

pure virtual

Provides scene corner points in lat, lon given frame time in seconds since start of sequence.

Returns TRUE if polygon valid.

frameCenter()

virtual bool ossimVideoGeometry::frameCenter ( const double &  t, ossimGpt &  centerGpt  ) const

pure virtual

Provides scene center position in lat, lon, hgt given frame time in seconds since start of sequence.

Returns TRUE if point valid.

frameSize()

virtual const ossimIpt& ossimVideoGeometry::frameSize ( ) const

pure virtual

Access method returns number of pixels in a frame.

getImageGeometry()

virtual ossimRefPtr<ossimImageGeometry> ossimVideoGeometry::getImageGeometry ( const double &  t )

pure virtual

Provides an image geometry object for frame at specified time in seconds since start of sequence.

Returns TRUE if point valid.

Referenced by ossimVideoImageSource::getImageGeometry(), and ossimVideoImageHandler::getImageGeometry().

sensorAttitude()

virtual bool ossimVideoGeometry::sensorAttitude ( const double &  t, double &  X_deg, double &  Y_deg, double &  Z_deg  ) const

pure virtual

Provides platform attitude in degrees given frame time in seconds since start of sequence sequence.

Returns TRUE if parameters valid. The coordinate system is defined by the derived class (can represent for example Euler rotations about an ECF, ENU or roll, pitch, heading)

sensorFocalLength()

virtual bool ossimVideoGeometry::sensorFocalLength ( const double &  t, double &  focal_len_meters  ) const

pure virtual

Provides focal length in meters given frame time in seconds since start of sequence.

Returns TRUE if parameters valid.

sensorPosition()

virtual bool ossimVideoGeometry::sensorPosition ( const double &  t, ossimGpt &  gpt  ) const

pure virtual

Provides platform position in lat, lon, hgt given frame time in seconds since start of sequence.

Returns TRUE if point valid.

videoBoundingRect()

virtual bool ossimVideoGeometry::videoBoundingRect ( ossimDrect &  geo_rect ) const

pure virtual

Provides the bounding rect that covers all frames in the full video.

Returns TRUE if rect valid.
