Claim 6:
7. A computer vision system for a drilling rig, the system comprising:
one or more cameras, wherein each camera has a field of view that includes a region of interest, wherein the region of interest comprises a region above a borehole of a well being drilled by a drilling rig; and
a computer vision processor operably coupled to the one or more cameras, the computer vision processor configured to receive, from the one or more cameras, visual data relating to a drill pipe segment in the region of interest, and configured to provide instructions to at least one piece of equipment of the drilling rig, wherein the computer vision processor is adapted to:
analyze the visual data;
detect an object in the visual data as a pipe by:
estimating a background from the visual data;
detecting a change in the background;
identifying the object as the pipe based on the change meeting a predetermined change in information and meeting predefined shape and size constraints, wherein, upon identifying the pipe, the processor is configured to halt background updating while the identified object is present in the field of view; and
updating the background estimation based on the change not meeting the predetermined change in information;

measure a length or a diameter based on the detection of the object as the pipe and based on a number of pixels in the visual data comprising the pipe;
determine at least one state specific variable based on the visual data;
update a pipe tally report based on the detection of the object as the pipe and based on at least one of the at least one state specific variable meeting a predefined condition or the measured length or diameter of the pipe; and
interrupt operations of the at least one piece of equipment based on the visual data being outside a pre-determined set of conditions.
