sarkit.cphd.planar_iac_to_ecf

planar_iac_to_ecf(pt_iac, iarp, uiax, uiay)

Convert from IAC coordinates to ECF coordinates for Surface Type = PLANAR

Parameters:

pt_iac(…, 2) or (…, 3) array_like

Array of positions in IAC coordinates with IAX, IAY, IAZ components in meters in the last dimension. When last dimension is of length 2, the IAZ component is assumed to be 0.

iarp(3,) array_like

IARP position in ECF coordinates (m).

uiax, uiay(3,) array_like

Image area x-coordinate and y-coordinate unit vectors in ECF coordinates.

Returns:

pt(…, 3) ndarray

Array of positions in ECF coordinates with X, Y, Z components in meters in the last dimension.
