Patent ID: 8855404

Claim:
A method for inspecting a workpiece, said method comprising: storing model data associated with the workpiece in an inspection system; determining a relative position of a depth sensing device relative to the workpiece; calibrating a pose view for the inspection system relative to the model based on the position of the depth sensing device relative to the workpiece; measuring actual depth distance data of at least one pixel of the depth sensing device relative to the workpiece; and determining, based on the actual depth distance data, if the workpiece satisfies predetermined inspection criteria, wherein determining if the workpiece satisfies predetermined inspection criteria comprises: calculating model depth distance data for the pose view of the inspection system, wherein model depth distance data represents a model depth distance from the pose view of the inspection system to the model workpiece; determining whether the actual depth distance differs from the model depth distance; and determining whether the difference satisfies the inspection criteria when the actual depth distance differs from the model depth distance, wherein compliance with a threshold indicates the workpiece is in acceptable condition.
