Interactive recognition of hand-drawn circuit diagrams

[摘要] When designing electronic circuits, engineers frequently make hand-drawnsketches of circuits. These are then captured with a computerised design.This study aims to create an alternative to the common schematic captureprocess through the use of an interactive pen-based interface to thecapturing software.Sketches are interpreted through a process of vectorising the user's strokesinto primitive shapes, extracting information on intersections between primitivesand using a naive Bayesian classifier to identify symbol components.Various alternative approaches were also considered.It is concluded that it is feasible to use a pen-based interface and underlyingrecognition engine to capture circuit diagrams. It is hoped that this wouldprovide an attractive early design environment for the engineer and enhanceproductivity.
