A system includes a console assembly, a trocar assembly operably coupled to the console assembly, a camera assembly operably coupled to the console assembly having a stereoscopic camera assembly, and at least one rotational positional sensor configured to detect rotation of the stereoscopic camera assembly about at least one of a pitch axis or a yaw axis. The console assembly includes a first actuator and a first actuator pulley operable coupled to the first actuator. The trocar assembly includes a trocar having an inner and outer diameter, and a seal sub-assembly comprising at least one seal and the seal sub-assembly operably coupled to the trocar. The camera assembly includes a camera support tube having a distal and a proximal end, the stereoscopic camera operably coupled to the distal end of the support tube and a first and second camera module having a first and second optical axis.

An apparatus includes an interface and a processor. The interface may be configured to receive pixel data representing respective fields of view of two or more cameras arranged to obtain a predetermined field of view, where the respective fields of view of each adjacent pair of the two or more cameras overlap. The processor may be configured to process the pixel data arranged as video frames and perform a fixed pattern calibration for facilitating multi-view stitching. The fixed pattern calibration may comprise applying a pose calibration process to the video frames. The pose calibration process generally uses (i) intrinsic parameters, a respective translate vector, a respective rotation matrix, and distortion parameters for each lens of the two or more cameras and (ii) a calibration board to obtain configuration parameters for the respective fields of view of the two or more cameras. The pose calibration process may comprise changing a z value of the respective translate vector for each lens of the two or more cameras to at least one of a middle distance value and a long distance value while maintaining the respective rotation matrix for each lens of the two or more cameras unchanged.
