Abstract

The invention discloses a painting method based on sinusoidal curve grayscale display, which uses a set trajectory (such as a spiral) to superimpose a sine wave for painting, the control scheme is simple, the requirements for the hardware system are low, and there is no need for complicated trajectory planning, a large number of Multi-degree-of-freedom mechanical structures such as complex calculations and complex robotic arms generate trajectories without redundancy and high efficiency. Robot painting can be realized with a hardware system of at least two degrees of freedom; there is no high requirement for the resolution of pre-drawn images , the content can be but not limited to photos, comics, or text, and the scope of use is wider; it supports personalized customization, and can modify parameters such as the center point, distance, number of turns, and amplitude of the sinusoidal curve according to personal preferences and aesthetics , it is easy to generate different painting trajectories.

Description

A painting method based on sine curve grayscale display technical field The invention belongs to the field of computer graphics, can be used for drawing pictures quickly and with high precision, and will be used in robot painting and stimulation. Light engraving and other fields have important applications. Background technique Robot technology is a very important high-tech new technology in contemporary times, involving control technology, computer technology, transmission The intersection and integration of sensor technology, bionics and other disciplines. With the development of robot technology, its application scope is gradually expanding. It has expanded from the industrial field to all walks of life. With the continuous deepening of research on robotics, people gradually tend to In order to study humanoid robots that can imitate specific human behaviors, writing and drawing are one of the important characteristics of human beings. It is one of the desires ...
