StellarOpNav.id_stars

giant.stellar_opnav.stellar_class:

StellarOpNav.id_stars()

This method identifies stars for each image turned on in the camera attribute.

The steps for performing the star identification are as follows:

1. Potential star locations are extracted from each image using the ImageProcessing.locate_subpixel_poi_in_roi() method for each image (if this step has not been already performed). The subpixel points of interest from this step are then passed to the StarID object as the StarID.extracted_image_points attribute.

2. The StarID object is further updated with the a priori attitude, the camera position and velocity, and the observation date for each image.

3. The stars are identified using the routines in the StarID.id_stars() method.

4. The results from the star identification are stored into the various properties of this class for each image.

For more information about the star identification process see the StarID documentation
