Abstract
The 3-D foot-shape measurement system based on laser-line-scanning principle was designed and 3-D foot-shape measurements without blind areas and the automatic extraction of foot-parameters were achieved. The paper is focused on the study of the system structure and principle and image processing techniques. The key techniques related to the image processing for 3-D foot shape measurement system include laser stripe extraction, laser stripe coordinate transformation from CCD cameras image coordinates system to laser plane coordinates system, laser stripe assembly of eight CCD cameras and eliminating of image noise and disturbance. 3-D foot shape measurement makes it possible to realize custom-made shoe-making and shows great prosperity in shoe design, foot orthopaedic treatment, shoe size standardization and establishment of a feet database for consumers.
