“…Stereo matching technology is one of the key technologies of visual servo system. [8][9][10] According to different principles, it can be divided into three forms: the first is the region-based matching algorithm. The principle of this algorithm is to set the field around the target feature point, establish a template according to the gray value of pixels in the field, and then find the correlation in the picture to be matched to find out the gray distribution similar to or the same as the template.…”

BackgroundWith the development and progress of society, not only substations, but also various industries are moving towards automation, intelligence, and unmanned direction. There is an increasing need for machinery to replace human activities. However, how to improve the ability of robotic arms to cope with various working environments and emergencies, and develop real‐time, high‐speed, and accurate trajectory planning algorithms has become a hot topic of discussion.PurposeIn order to develop a reasonable trajectory planning algorithm for robotic arms, this article studies the trajectory planning algorithm of robotic arms based on visual servoing, in order to improve the trajectory operation ability of robotic arms.MethodThe feasibility of the algorithm was tested through experiments.ResultsIt was found that the angle, angular velocity, and angular acceleration curves of both the second and fifth sixth joints of the robotic arm were very smooth, and there were no problems such as faults.ConclusionThis confirms the effectiveness of the algorithm's operation, which can assist the robotic arm in safe, accurate, and efficient operations on the basis of visual servoing.
