1. A computer vision system for personnel location on a drilling site, the system comprising:
a plurality of cameras, each positioned on the drilling site, wherein the drilling site comprises a drilling rig and one or more pieces of equipment associated with the drilling rig;
at least one processor operably connected to the plurality of cameras and configured to receive visual data from the plurality of cameras, wherein the visual data comprises a field of view of at least a portion of the drilling site, and wherein the processor is further configured to:
detect one or more personnel in the field of view from the visual data;
estimate a location of one or more personnel on the drilling site in the field of view from the visual data and based on the detection of the one or more personnel; and
determine, from the visual data, if the detected one or more personnel at the estimated location comprises a predetermined safety condition; and
a control system coupled to the processor and the drilling rig or the one or more pieces of equipment, wherein the processor is configured to send a signal to the control system when the predetermined safety condition is determined and, responsive to the signal, the control system initiates a corrective action.
