A moving vector corresponding to a difference between difference frames scanned by the optical scanning device at different moments is calculated so that an instant location of the frame center on the displaying medium can be calculated anytime. Therefore, a large number of calculations brought by frequent decoding may be saved since merely a few calculations are required in calculating the moving vector. By further decoding the coordinate of the frame center at moments spaced with constant or variable intervals, errors brought by vibrations of the displaying medium are instantly fixed. Accumulated errors are avoided in the calculated instant locations of the frame center anytime."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of determining coordinate on micro dotmap according to moving vector","description":"When a user holds an optical scanning device to scan a micro dotmap on a displaying medium, a coordinate of a frame center of a retrieved frame on the displaying medium is calculated according to a de","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8513546","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.
