Systems and techniques for capturing images for use in determining reflectance properties of physical objects

摘要

Systems and techniques are disclosed that use an image capture device to capture images of an object under specified image capture conditions for use in determining reflectance properties of the object. Images of the object are captured from a variety of different camera directions and with the object illuminated from a variety of different light directions. To capture these images, a camera of the image capture device is moved relative to the object and lights of the device are selectively illuminated. The image capture device has various features that increase the variety and number of different image capture conditions that can be captured. For example, using planar arrays of individually addressable lights in the image capture device allows tens, hundreds, or even thousands of lights to be used. Using planar arrays of lights provides light from many different directions without adding substantial complexity or cost to the device.
