Abstract
A method and apparatus for generating machining code of workpieces from a paper engineering drawing are provided. The method includes processing the paper engineering drawing to be a binary image; extracting dimension features and shape features of the workpieces from the binary image; and generating the machining codes of the workpieces based on the extracted dimension features and shape features of the workpieces. The machining codes indicate the dimension and shape of the workpieces. Machining codes of workpieces are generated from a paper engineering drawing directly without manual involvement.
