The present invention takes advantages of accurate range measurement of laser tracker as a constraint to achieve the followings: obtaining high accuracy 3-d coordinates of global control points, constructing precision coordinate control network and using it as the measurement standards of wMPS, achieving on-site accuracy traceability, and thus improving the measurement accuracy of wMPS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Accuracy traceability method based on precision coordinate control network for workshop measurement positioning system","description":"The present invention relates to an accuracy traceability method based on precision coordinates control network for workshop Measurement Positioning System, which includes the steps: setting a plurali","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9658055","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.
