A Machine Vision Inspection Algorithm for Information Extraction of Logic Circuit Diagram

Abstract

The invention discloses a machine vision detection algorithm for information extraction of logic circuit diagrams, which specifically includes the following steps: S1. Color threshold for multi-pin component information extraction: using the Color Threshold color threshold algorithm to obtain the position information of multi-pin components, firstly Selecting the RGB color model, according to the color of the multi-pin component name, involves the field of electrical technology. The machine vision detection algorithm for information extraction of logic circuit diagrams can extract circuit information in logic circuit diagrams by using image recognition algorithms, convert them into text descriptions, and adapt their text formats to different circuit design software. Then, the text can be imported into The circuit design software automatically generates logic diagrams, which greatly simplifies the reproduction process of logic circuit diagrams. It does not require people to spend a lot of time analyzing, transforming and drawing logic diagrams. It realizes intelligent identification of circuit diagrams through intelligent algorithms, and automatic extraction and transformation. into a logic diagram.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a machine vision detection algorithm for extracting logic circuit diagram information. Background technique [0002] A logic circuit is a discrete signal transmission and processing circuit based on the principle of binary to realize logical operations and operations of digital signals. The former consists of the most basic "AND" circuit, "OR" circuit and "NOT" circuit. , whose output value only depends on the current value of its input variable, and has nothing to do with the past value of the input variable—that is, it has no memory and storage functions; the latter is also composed of the above-mentioned basic logic gate circuits, but there is a feedback loop—its output value is not only Depends on the current value of the input variable and also depends on the past value of the input variable. Because it only divides high and low levels, has strong anti-interference abil...
