inverse: StereoscopicImagesTransformation This operation returns another Stereoscopic Images Transformation object that reverses the
actions of this Stereoscopic Images Transformation object. The target of the inverse transformation is the source of the original, and the source of the inverse transformation is the
target of the original. Using the original transform followed by the inverse transform will result in an identity map on the source coordinate space, when allowances for error are made.
4.1.8. Class Name: PointStereoscopicImagesTransformation
Package Class Belongs to: Image Transformations Documentation:
This class defines a coordinate transformation operation that determines one 3-D ground position corresponding to the specified positions in two or more stereoscopic images. This
class alternately defines an operation that transforms the coordinates of one ground point position into the corresponding image coordinates in two or more images.
Note that the input and output positions are of type DirectPosition, in order to include the association to the proper SpatialReferenceByCoordinates which is needed with some input
and output positions. However, each DirectPosition includes position accuracy data, which is not needed with the input and output positions.

Operations:
transform points: Sequence DirectPosition: Sequence DirectPosition This operation performs one of two similar functions, depending on whether the source
SpatialReferenceByCoordinates is a ground or image coordinate system. When the source is a ground coordinate system, this operation transforms the specified
position of one point given in the source ground coordinate system to the corresponding positions of the point in two or more images.
When the source is an image coordinate system, this operation computes the one position in the source ground coordinate system that best fits the specified positions of this point in each
of two or more images. derivativeMatrix points: Sequence DirectPosition: SequenceMatrix
This operation performs one of two similar functions, depending on whether the source SpatialReferenceByCoordinates is a ground or image coordinate system.
When the source is a ground coordinate system, this operation returns a list of matrices of the partial derivatives of the image coordinates with respect to the source ground coordinates.
These partial derivatives are determined at the one specified position in the source ground coordinate reference system. The returned list of partial derivative matrices includes a matrix
for each image used by this object.
When the source is an image coordinate system, this operation returns a list of matrices of the partial derivatives of the ground coordinates with respect to the image coordinates in two or
more images. These partial derivatives are determined at the specified positions in these images, which are normally the positions of the same ground point in the different images.
4.1.9. Class Name: ListStereoscopicImagesTransformation
Package Class Belongs to: Image Transformations Documentation:
This class defines a coordinate transformation operation that determines a list of one or more 3-D ground positions, each corresponding to the specified positions in two or more
stereoscopic images. This class alternately defines an operation that transforms one or more

ground point position coordinates, each point into the corresponding image coordinates in two or more images. The lists can contain one or more points.
Note that the input and output positions are of type DirectPosition, in order to include the association to the proper SpatialReferenceByCoordinates which is needed with some input
and output positions. However, each DirectPosition includes position accuracy data, which is not needed with the input and output positions.

This operation performs one of two similar functions, depending on whether the source SpatialReferenceByCoordinates is a ground or image coordinate system. In both cases, the
output list contains the same number of points in the same order as the input lists no densification is performed.
When the source is a ground coordinate system, this operation transforms the specified list of one or more point positions in the source ground coordinate system to the corresponding
positions of each point in two or more images. When the source is an image coordinate system, this operation computes the list of one or
more positions in the source ground coordinate system that best fit the specified positions of this point in each of two or more images.

When the source is a ground coordinate system, this operation returns a list of matrices of the partial derivatives of the image coordinates with respect to the source ground coordinates.
These partial derivatives are determined at the one or more specified positions in the source ground coordinate reference system. For each ground point, the list of partial derivatives
matrices includes a matrix for each image used by this object.
When the source is an image coordinate system, this operation returns a list of matrices of the partial derivatives of the ground coordinates with respect to the image coordinates in two or

This is done for one or more points in the ground coordinate system.
