Apparatus and Method for Measuring Optical Characteristics Using a Camera and a Calibration Chart Imaged with the Camera

摘要

A method including the determination of color information of an object is disclosed. 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 of the image generation device. Data is generated of the reference implement, which includes a positional location attribute. Based on the positional location attribute a position of the one or more regions of predetermined optical properties of the reference implement in the field of view of the image generation device is determined by a processing system without operator identification of the position of the reference implement in the field of view of the image generation device. 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. The color information may be transmitted electronically to a remote location. The object may be human skin. The object and the reference implement may be positioned so as to be subject to a substantially corresponding lighting condition.
