An examination of displaying reassembly procedure by recording disassembly procedure with AR markers

Abstract

Some objects that can be assembled are disassembled and then reassembled for purposes such as maintenance and research of each part. When reassembling such objects, we reassemble it using images and illustrations that have been assembled, records of assembly methods. But if the assembly information is not sufficient, it may takes time to assemble. One solution is to record image the disassembly procedure. However, in this case, it is very difficult to associate the image with the parts, and if there are many similar parts, some parts may be mistaken or the exact direction of the parts may not be known. In this paper, we propose a method to display reassembling procedure by recording disassembling procedure of products. Specifically, the state when the parts are separated from the product is recorded together with the augmented reality (AR) marker, and the separated parts are associated with the AR marker. The AR marker are made to record the reading order so that the AR marker can be read and sort in the disassembled order when reassembly. By sorting the AR markers, the order of the parts used during reassembly becomes clear. By reproducing the disassembled information in the reverse order, the finished product reassembly can be finished without trial and error.
