Abstract

Computer device (33) for determining an appropriate positioning of an instrumentation on a target bone area (200) according to a relative positioning (42) of said instrumentation to said target bone area defined by a surgical planning (32), said device comprising—an interface for receiving from a 3D camera (31) a depth map (41) of a captured scene (310) comprising at least said target bone area; —computing means for determining a position element of said target bone area from said depth map; determining a second positioned shape (442) of said target bone area according to said relative positioning (42), and determining data (43) representative of said appropriate positioning on the base of said second positioned shape (442) and said position element; —a human-machine interface for providing said data.
