Intelligent sketch drawing method and device, storage medium and terminal equipment

Abstract

The invention discloses an intelligent sketch drawing method. The method comprises the steps that S1, acquiring an image of a drawing object through an acquisition device; S2, performing gray processing on the drawing object image through an algorithm to obtain a gray image; S3, taking the center of the gray level image as a starting point of a spiral structure drawing, and establishing a spiral line outwards circle by circle through a polar coordinate equation until each point in the gray level image is contained in the spiral line; S4, dividing the gray value into a plurality of gray intervals, and setting drawing path description times for each interval; S5, calculating the description frequency of the interval to which the gray value of the point of the gray image corresponding to eachpoint of the spiral line belongs; S6, dividing adjacent points with the same number of times of drawing into a section, and dividing the spiral line into a plurality of groups of drawing paths according to the number of times of drawing of each point of the spiral line to obtain a spiral structure description path of the drawn image; and S7, generating an electric processing signal according to the spiral structure description path, and controlling the mechanical arm to draw.

Description

technical field [0001] The invention relates to the field of robot drawing, in particular to an intelligent sketch drawing method, device, storage medium and terminal equipment. Background technique [0002] With the development of science and technology, the application fields of intelligent robots are becoming more and more extensive, and intelligent robots are also widely used in daily life, and robots that can draw pictures will also be welcomed by people. [0003] Sketch is the earliest form of painting that appeared in human history, and it is also the oldest artistic language; sketch can use monochromatic lines or smeared into surfaces to express things in the intuitive world, and can also express ideas, concepts, attitudes, feelings, fantasies , symbolic and even abstract forms; therefore, painting robots should also have this unique sketching ability in terms of painting skills. [0004] The painting robots in the prior art all obtain the painting image and directl...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides an intelligent sketch drawing method, device, storage medium and terminal equipment to solve the technical problem that the drawing robot in the prior art directly recognizes the lines of the image to draw, so that the drawing can be done according to the light and dark sides of the image and the required color depth. Draw, and then increase the realism of the mechanical sketch and enhance the painting effect
