A machine vision detection algorithm for logic circuit diagram information extraction

Abstract

The invention discloses a machine vision detection algorithm for extracting logic circuit diagram information, The method comprises the following steps: S1, color threshold value of multi-pin component information extraction: adopting Color Threshold color threshold algorithm to obtain position information of multi-pin component, firstly selecting RGB color model, and according to the color of multi-pin component name, the invention relates to the technical field of electricity. The machine vision detection algorithm of the logic circuit diagram information extraction, the circuit informationin the logic circuit diagram can be extracted by adopting an image recognition algorithm, Convert to Text Description, so that the text format can be adapted to different circuit design softwares, Then, the text can be imported into circuit design software to generate logic diagrams automatically, which greatly simplifies the process of reproducing logic circuit diagrams and eliminates the need for people to spend a lot of time on analyzing, converting and drawing logic diagrams. The intelligent identification of circuit diagrams by intelligent algorithms is realized, and the logic diagrams are automatically extracted and converted into logic diagrams.

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...
