poIImagePlane ReprojectionError

Calculate the reprojection error between the current multi-point alignment points.

Syntax

Imageplane_handle ReprojectionErrors pointList

Application

HyperView Tcl Query

Description

This command returns a calculation (float) of the projection error that would result from an alignment based on the point list.

Inputs

pointList
A string containing at least seven corresponding model and image points that will be used for an alignment.
The string is in the following format: # of points, model node locator strings, x y image points. This is the same format that is returned from GetAlignmentData when the alignment mode is set to IP_MULT_POINT.

Example

To determine if the sync scale has been modified:

page_handle GetWindowHandle window_handle [page_handle GetActiveWindow]
window_handle GetClientHandle client_handle
client_handle GetImagePlaneCtrlHandle ipc_handle
ipc_handle GetImagePlaneHandle image_plane_handle 1

Errors

Returns HW_InvalidHandle if the image plane handle is invalid, or HW_InvalidArgs if the invalid point list is passed.
