Systems and methods for orientation detection and tool installation

An apparatus comprising:

• a processor;
• and
• a memory having computer readable instructions stored thereon, the computer readable instructions, when executed by the processor, cause the apparatus to:
• capture, via an image sensor of a tool installed at least partially within a catheter, a first image within a lumen of the catheter, the first image comprising a plurality of pixels;
• identify a first subset of the plurality of pixels comprising a viewable feature, and a second subset of the plurality of pixels comprising a background color;
• adjust the second subset to a neutral color;
• create a modified image by filtering the plurality of pixels to remove the second subset;
• determine an angular orientation of the viewable feature in the modified image;
• determine a rotational offset of the tool relative to the catheter based on the angular orientation of the viewable feature;
• and
• based on the rotational offset:
• (1) adjust manipulation of a control cable of the catheter;
• or (2) rotate one or more images captured by the image sensor.
