Functions

camera_coordinates_to_xyz(horizontal, ...)

Converts from (horizontal,vertical) pixel measurements from the OAV camera into to (x, y, z) motor coordinates in millmeters.

dodal.devices.oav.oav_calculations.camera_coordinates_to_xyz(horizontal: float, vertical: float, omega: float, microns_per_i_pixel: float, microns_per_j_pixel: float) → ndarray[source]#

Converts from (horizontal,vertical) pixel measurements from the OAV camera into to (x, y, z) motor coordinates in millmeters. For an overview of the coordinate system for I03 see DiamondLightSource/hyperion.

Parameters:

horizontal (float) – A i value from the camera in pixels.
vertical (float) – A j value from the camera in pixels.
omega (float) – The omega angle of the smargon that the horizontal, vertical measurements were obtained at.
microns_per_i_pixel (float) – The number of microns per i pixel, adjusted for the zoom level horizontal was measured at.
microns_per_j_pixel (float) – The number of microns per j pixel, adjusted for the zoom level vertical was measured at.

Return type:

ndarray
