[Objective] This study proposes a size-adaptive template matching algorithm to quickly construct large-scale data set for academic literature figure and table positions. [Methods] First, we used the PubMed Open Access database to retrieve documents with figure/table images, and parsed their contents. Then, we matched document pages and pictures to extract their features. Finally, we identified the figure/table positions based on matched feature points. [Results] The proposed method’s precision and F1 value reached 98.87% and 97.44%, respectively. [Limitations] We only used simple keywords to match literature pages and figure/table pictures. [Conclusions] ;The proposed algorithm could quickly construct data set for chart positions in academic literature.
