Abstract: An example system includes two objects each having a known dimension and positioned spaced apart by a known distance, and a fixture having an opening for receiving an imaging device and for holding the two objects in a field of view of the imaging device such that the field of view of the imaging device originates from a point normal to a surface of the base. The fixture holds the imaging device at a fixed distance from an object being imaged and controls an amount of incident light on the imaging device. An example method of determining image scaling includes holding an imaging device at a fixed distance from an object being imaged, and positioning the two objects in the field of view of the imaging device such that the field of view of the imaging device originates from a point normal to a line formed by the known distance.

Abstract: An example fixture includes a hollow elongate section having a first end and a second end, and the first end has an opening for receiving a lens portion of an imaging device and the second end is structurally configured to brace against a surface of an object being imaged. The hollow elongate section is configured to hold the lens portion of the imaging device at a fixed distance from an object being imaged and to control an amount of incident light on the lens portion. Example methods of configuring an imaging device for capturing images of an object include holding, via a fixture, a lens portion of an imaging device at a fixed distance from an object being imaged, controlling an amount of incident light on the lens portion of the imaging device, and holding a calibration object in a field of view of the imaging device.
