摘要： A method for determining color information of an object, wherein data is generated of the object with an image generation device having a field of view. The object and a reference implement having one or more regions of predetermined optical properties are positioned in the field of view. Data is generated of the reference implement, which includes a positional location attribute, based on which a position of the one or more regions of predetermined optical properties is determined by a processing system without operator identification of the position of the reference implement in the field of view. Color information of the object is generated by adjusting the data generated of the object based on the data generated of the reference implement. The color information may include value, chroma and hue information, RGB values, XYZ coordinates, or Lab values, and may be transmitted electronically to a remote location.
