Claim 17:
18. A system, comprising:
a data transceiver, capable of receiving input parameters including downhole conditions and at least one visual frame of a drill string, wherein the at least one visual frame is received from one or more image devices located at a surface location of a borehole undergoing a drilling operation, where the one or more image devices are not in contact with the drill string, the drill string is coupled to a surface equipment of the borehole, and the drill string is undergoing a trip in operation or a trip out operation at the borehole;
a result transceiver, capable of communicating a casing wear parameter; and
a casing wear processor, capable of using the input parameters to generate the casing wear parameter by calculating a metal wear on a section of casing, wherein each visual frame is analyzed by the processor for a surface change in a surface of the drill string, where the metal wear is determined utilizing the surface change, the section of casing is identified by correlating the drill string location in the borehole during an active drilling portion of the drilling operation and the drill string was in contact with the section of casing, the casing wear parameter is determined by correlating the surface change of the drill string to the section of casing, and the casing wear parameter is used to replace the section of casing or to modify a weight-on-bit, a drill string rotation rate, a drill string size, a mud density, a mud rheology, a mud velocity, or a pipe eccentricity.
