Assembly Guidance Technology for Augmented Reality in Narrow Spaces Based on Wearable Devices
Assembly efficiency is the key factor restricting the increase in production of advanced fighter jets in China.There is a problem of narrow assembly areas,where workers cannot see the relative positions of parts and assembly areas,and rely solely on tactile feedback for assembly.A augmented reality assembly guidance technology for narrow spaces is proposed,the methods based on FAST detection and SIFT description for feature point detection are utilized.By improving the binocular matching method of Census transformation,feature point matching is achieved.The experimental results show that the wearable augmented reality assembly guidance method has an efficiency improvement of 24.75％compared with the traditional assembly methods,and the accuracy has been improved from 95％to 99％.This intelligent method can significantly improve the efficiency and quality of narrow area component assembly.
