Abstract

Purpose

–

To develop an image processing approach for jigsaw puzzle assembly.

Design/methodology/approach

–

First, pixels are extracted from the jigsaw puzzle blocks to calculate their rotation angles and centre coordinates. Second, a template matching method is employed to recognise each block and its orientation.

Findings

–

A robot‐based jigsaw puzzle system is established; and an effective image processing approach for assembly is developed.

Practical implications

–

Automatic assembly lines that assemble parts with the same shape, but random position and angle, can employ the jigsaw puzzle assembly method.

Originality/value

–

An effective image processing method for jigsaw puzzle assembly is presented in this paper. The validity of the method is proved by analysis and experiment.
