Abstract

Purpose

Computer‐aided fragmented cultural relics repair is an effective method instead of manual repair. The purpose of this paper is to provide a 3D digital patching system for computer‐aided cultural relics repair through using the scanned 3D data of fragmented cultural relics. It includes processes and tools that can be effectively used for fragmented cultural relics repair.

Design/methodology/approach

An automatic 3D digital patching for fragmented culture relics repair is designed. The framework includes a surface segmentation based on region dilation, feature extraction based on height‐map, pair matching and multi‐block matching.

Findings

The paper finds that the proposed 3D data patching is an efficient method for fragmented cultural relics repair.

Practical implications

Early and effective planning and implementation of computer‐aided fragmented cultural relics repair can significantly improve the reliability and availability of fragmented cultural relics repair.

Originality/value

The paper presents a uniform framework of 3D digital patching for fragmented cultural relics repair.
