SYSTEMS AND METHODS FOR ESTIMATING NEEDLE POSE

A system for tissue suturing guidance in a surgical site includes an imaging device configured to capture an image of a surgical needle within the surgical site and an imaging device control unit configured to control the imaging device. The imaging device control unit includes a processor and a memory. The memory stores instructions which, when executed by the processor, cause the system to capture an image of a surgical needle and a surgical tool within the surgical site via the imaging device, estimate a pose of the surgical needle based on the captured image, generate an augmented image based on the estimated pose of the surgical needle, and display on a display, the augmented image of the surgical needle
