Zusammenfassung:The invention discloses a navigation data table positioning method, system and device and a storage medium, and the method comprises the steps: carrying out the preprocessing of navigation data, and obtaining a navigation data picture; on the basis of grouped convolution, a reverse bottleneck structure, an SE attention mechanism and a feature pyramid structure, performing feature extraction on the navigation data picture to obtain a feature map; inputting the feature map into an RPN region suggestion network for target table positioning to obtain a suggestion box; according to the feature map and the suggestion box, adopting a cubic convolution interpolation algorithm to obtain a suggestion feature map; and performing bounding box regression processing on the suggested feature map to obtain a table region of the navigation data picture. According to the embodiment of the invention, a cubic convolution interpolation mode is introduced to carry out feature mapping, and feature image pixel loss caused by forced
