Abstract: A virtual-real fusion and precise positioning method is proposed based on augmented reality devices. Through multi-sensor environmental perception technology, a three-dimensional model of the cable tunnel and three-dimensional coordinate acquisition are constructed, and real-time information on the direction, position, and operating status of the head(equipment)are obtained. By using simultaneous localization and mapping(SLAM)technology, real-time construction and updating of environmental maps can be achieved and obtained the location of virtual content and human-computer interaction. By optimizing the differential positioning technology of the global navigation satellite system(GNSS), the stability and accuracy of the SLAM system and the positioning accuracy are improved. The experimental result is shown that the positioning error of the proposed method described in the article does not exceed 10 cm, indicating good practicality.
