providing, by a computer processor, the plurality of parameters as input to a machine learning model of the drilling rig; and
analyzing, by the computer processor and based on the machine learning model, the plurality of images to generate the slips status.

2. The method of claim 1 , further comprising:
generating, by the computer processor and based at least on the slips status, slips status statistics comprising one or more of an elapsed slips-to-slips time, an elapsed slips-to-weight time, an elapsed weight-to-slips time, and an elapsed weight-to-weight time.

3. The method of claim 2 , further comprising:
generating, by the computer processor and based at least on the slips status statistics, one or more of an alert and an actionable item; and
presenting, to a user, one or more of the slips status statistics, the alert, and the actionable item.

4. The method of claim 1 , further comprising:
performing, by the computer processor, the drilling operation based at least on the slips status.

5. The method of claim 1 , further comprising:
obtaining, in real-time and using one or more surface sensors of the drilling rig, the plurality of parameters of the drilling rig,
