摘要：
One variation of a method for tracking objects within a surgical space during a surgery includes: based on a first image depicting the surgical space at a first time, detecting a first object and a constellation of objects in the surgical space, estimating distances from each object—；in the constellation of objects—；to the first object, and calculating a contamination risk of the first object based on contamination scores and distances to the first object for each object in the constellation of objects； calculating a contamination score of the first object based on a combination of the contamination risks of the first object during the surgery； and, in response to the contamination score of the first object exceeding a threshold contamination score prior to contact between the first object and a patient, serving a prompt within the surgical space to address sterility of the first object.
