Methods and systems for calibrating an imaging system having a plurality of sensors are disclosed herein. In some embodiments, a method includes initially calibrating the imaging system, operating the imaging system during an imaging procedure, and then updating the calibration during the imaging procedure to account for degradation of the initial calibration due to environmental factors, such as heat. The method of updating the calibration can include capturing image data of a rigid body having a known geometry with the sensors and determining that the calibration has drifted for a problematic one of the sensors based on the captured image data. After determining the problematic one of the sensors, the method can include updating the calibration of the problematic one of the sensors based on the captured image data.

Methods and systems for calibrating and/or verifying a calibration of an imaging system such as a surgical imaging system

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.

Methods and systems for calibrating instruments within an imaging system, such as a surgical imaging system

Mediated-reality imaging systems, methods, and devices are disclosed herein. In some embodiments, an imaging system includes (i) a camera array configured to capture intraoperative image data of a surgical scene in substantially real-time and (ii) a processing device communicatively coupled to the camera array. The processing device can be configured to synthesize a three-dimensional (3D) image corresponding to a virtual perspective of the scene based on the intraoperative image data from the cameras. The imaging system is further configured to receive and/or store preoperative image data, such as medical scan data corresponding to a portion of a patient in the scene. The processing device can register the preoperative image data to the intraoperative image data, and overlay the registered preoperative image data over the corresponding portion of the 3D image of the scene to present a mediated-reality view.
