The height of the top drive is a height from the top drive to the rotary table surface. A pixel relationship table may be established between the quantity of the pixels from the top drive to the rotary table surface and the height of the top drive by a calibration unit of the operating terminal to finish drilling calibration. The pixel relationship table may be determined between the quantity of the pixels from the top drive to the rotary table surface and the height of the top drive by an image recognition technique to finish calibration of drilling, so that influence of a drilling environment to drilling calibration may be reduced greatly."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Drilling calibration method, apparatus, device and medium based on image recognition","description":"A drilling calibration method, apparatus, device and medium based on image recognition includes lifting a top drive to a position of a derrick, and receiving and recognizing a target image acquired by","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11494931","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
