1. A system to produce a replacement anatomical structure, comprising:
- a quantitative three-dimensional (Q3D) endoscope including an imaging sensor array comprising a plurality of imaging sensors, wherein each imaging sensor includes a corresponding lens stack and a two-dimensional arrangement of pixels arranged in a focal plane of the lens stack, wherein at least three of the imaging sensors of the imaging sensor array are disposed to have coplanar fields of view that overlap, and wherein the corresponding lens stack of each imaging sensor creates a separate optical channel that resolves an image of an anatomical structure within a field of view that includes target tissue in a focal plane of the corresponding lens stack;
at least one processor configured to;
produce a first Q3D model based upon image information captured from the anatomical structure that represents an external surface of bone tissue including the target bone tissue;
produce a second Q3D model based upon image information captured from the anatomical structure that represents remainder tissue structure, which defines an empty region in a location of the anatomical structure from which the target tissue has been tissue removed; and
produce a third Q3D model of a replacement structure that is shaped and dimensioned to fit against the remainder structure that defines the empty region and to substantially fill the empty region based at least in part upon the first Q3D model and the second Q3D model.
