Research on trajectory control of multi-degree-of-freedom industrial robot based on visual image

In order to improve the trajectory control effect of multi-degree-of-freedom industrial robots, this paper combines visual image technology to conduct research on trajectory control of multi-degree-of-freedom industrial robots. Aiming at the problem of video segmentation under sudden illumination changes, this paper uses a Gaussian mixture model based on the global illumination function to adopt a variety of illumination invariant features, and proposes a scene segmentation algorithm suitable for sudden illumination changes. Moreover, this paper compares and verifies the algorithm from the subjective and objective perspectives through experiments, which shows that the algorithm in this paper can segment the scene more accurately even in the environment of sudden changes in illumination. In addition, the results of the accuracy test and the trajectory control test show that the research method of the multi-degree-of-freedom industrial robot trajectory control based on the visual image proposed in this paper can effectively improve the trajectory control effect of the robot. © 2024 John Wiley & Sons Ltd.
