Systems and Methods of Determining Image Scaling

Abstract:

An example system includes a base, two objects each having a known dimension and positioned on the base spaced apart by a known distance, an imaging device positioned such that the two objects are in a field of view of the imaging device and such that the field of view of the imaging device originates from a point normal to a surface of the base, and a computing device having one or more processors and non-transitory computer readable medium storing instructions executable by the one or more processors to perform functions. The functions include receiving an image from the imaging device capturing the two objects in the field of view, and based on one or more of the known dimension of the two objects and the known distance between the two objects, determining an image scaling factor that associates a number of pixels in the image to a physical distance.
