Abstract

The invention discloses a drawing method, device and system based on a curved surface drawing carrier. The method comprises the steps that a curved surface drawing area is extracted from the curved surface drawing carrier, the curved surface drawing area is projected in a two-dimensional plane coordinate to obtain a projection area, and the size of the projection area is calculated to obtain the size of a two-dimensional plane; a target image is received, and the target image is subjected to image processing to obtain a binary image; pixel points of each image main body in the binary image arenumbered through a connected area marking method, and a drawing path is generated; the drawing path is stored in a grid with the same size as the two-dimensional plane, and then the drawing positionof each image main body is determined according to the positions of the pixel points of each image main body in the grid; and according to each drawing position, the distance between each drawing position and a drawing pen and the drawing path, the pixel points of each image main body are drawn one by one on the corresponding drawing positions. According to the method, device and system, automaticdrawing on the curved surface drawing carrier can be realized, and the labor cost is saved.

Description

technical field [0001] The invention relates to the technical field of automatic painting, in particular to a painting method, device and system based on a curved surface painting carrier. Background technique [0002] Traditional paintings, such as sketches, oil paintings, etc., are generally drawn on canvas or paper with a brush. The painting carrier is flat, the finished product is rigid and lacks texture, and the visual effect is limited. With the changes of the times and the development of contemporary art, the painting medium is rich and diverse, not only canvas or drawing paper, but also objects such as eggs, shoes, vases, etc. The painting medium is curved, and the finished product is novel, interesting and expressive. The visual effects are on full display. When the existing paintings based on curved surface painting carriers are all drawn by hand, it is laborious and time-consuming, and the labor cost is high.
