Abstract

The present invention relates to a panoramic three-dimensional registration system and method for augmented reality assembly, belonging to the field of augmented reality technology, and solves the problems of high registration error rate, small application environment size, high lighting requirement, high calculation amount of algorithm and low positioning accuracy in the prior art. Includes an iGPS transmitter for emitting a sector laser; IGPS reference ruler for calibrating the surveying coordinate system; An iGPS vector sensor for receiving a laser signal emitted from the transmitter; An iGPS workstation for obtaining coordinates of laser signal receiving points in an iGPS vector sensor; An imaging terminal for acquiring a realistic scene image; A calculation and display terminal is configured to perform coordinate transformation on the virtual information and superimpose the virtual information on a real scene image. The invention can realize panoramic three-dimensional registration of products of all sizes, visual field angles and any lighting environment without feature recognition. At the same time, the algorithm has low computational complexity and 0.2 mm positioning accuracy, which can be applied to the accurate display of augmented reality assembly process.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to a panoramic three-dimensional registration system and method for augmented reality assembly. Background technique [0002] Augmented reality is a new interactive technology developed along with virtual reality technology, which superimposes virtual information on the real environment in real time, so as to give people a visual experience of fusion of virtual and real. Augmented reality assembly refers to the process of applying augmented reality technology to the assembly site for assembly guidance, prompts and error correction. The three-dimensional registration method refers to how to determine the transformation relationship between the virtual scene and the real environment coordinate system, and superimpose the transformed virtual information on the real image. Traditional 3D registration methods for augmented reality assembly mainly include vision-based 3D regis...
