The rapid identification of the indicated position of electrical switches is the basic service of the MR intelligent interactive system.To minimize the computational burden,the state characteristics of different types of switches are analyzed,and the advantages of MR smart glasses in switch indication position recognition are introduced.Then,according to the different importance,the laser point cloud scanning technology is used to generate a three-dimensional model of the equipment object and the surrounding environment that considers both accuracy and data volume.Finally,visual SLAM algorithm based on feature point method and YOLOv3 algorithm technology are used to locate and quickly identify the switch indication position.The practical application shows that for the switch indication position on the equipment,the recognition rate of the quick identification method of electrical switch indication position based on MR technology is up to 100%,which meets the requirements of MR intelligent interactive system.
