Abstract

The invention provides an electrical experiment report identification method and device. The electrical experiment report identification method comprises steps of extracting a region map with components from an electrical experiment report; adopting an envelope analysis method to carry out convex hull separation on the components in the region map, and extracting a component contour map needing tobe identified; extracting a sharpened edge graph from the component profile graph by using a LOG operator; selecting an orthogonal axis of the centroid of the sharpened edge graph, and rotating the main axis to a horizontal direction to form a principal component edge contour graph; and comparing the principal component edge contour map with a standard contour map to determine an identification result. According to the electrical experiment report identification method provided by the embodiment of the invention, the electrical component can be segmented from the scanning image, then the information of the electrical component can be identified, the experiment result information in the experiment report can be effectively identified, and the method is simple and effective, high in identification accuracy, small in calculation amount and high in operability.
