Multi-view camera color calibration method using color checker chart

Abstract

A multi-view camera color calibration method using a color checker chart, includes measuring a brightness range of photographic data being input from multiple cameras; photographing the color checker chart for each camera and adjusting a brightness value of the chart to be within the brightness range of an input image of each camera; correcting brightness of each camera by using a gray patch of the checker chart; modeling a relationship between a color value of the checker chart obtained by each camera and a standard color value provided by the color checker chart; and correcting differences in color as a result of the modeling, to calibrate colors among the multiple cameras. Therefore, the three-dimensional information of a moving object for photography which cannot be photographed by moving only one camera is capable of being restored.
