Abstract
Methods and systems for calibrating an instrument, such as a surgical instrument, within an imaging system are disclosed herein. In some embodiments, a method includes capturing images of the instrument with a plurality of cameras of the imaging system and identifying common features of the instrument in the captured images. The method further includes generating a three-dimensional (3D) representation of the instrument based on the common features and determining a reference frame of the instrument based on the generated 3D representation of the instrument. A first transform is determined between the reference frame of the instrument and a reference frame of the cameras. Then, a second transform between the reference frame of the instrument and a reference frame of the tracking structure can be determined based on the first transform.
