Abstract
A surface characteristics evaluation method for evaluating a surface characteristic of a painted surface including a glittering material, including: a multi-angle condition image acquisition step Sfor acquiring a multi-angle condition image including multi-angle conditions in a continuous manner by performing an image-capturing process to capture how a reflection condition of the painted surface changes when rotating an illumination deviceemitting light onto the painted surface, the image-capturing process being performed by the line scan camerawhile a sample P having the painted surface is moved in a certain direction; an in-plane chromaticity distribution acquisition step Sfor acquiring an in-plane chromaticity distribution of the painted surface from the multi-angle condition image acquired; and a surface characteristics evaluation step Sfor calculating particle characteristics S as surface characteristics evaluation values of the multi-angle conditions, on the basis of the in-plane chromaticity distribution acquired.
