Claim 0:
1. A method of estimating target object dimensions within digital images, the method implemented by one or more computing devices and comprising:
obtaining a digital image containing a target object and a first reference object having a first fiducial pattern having a highly saturated color, wherein the first reference object further has at least one of:
an optical transmittance between about 2 percent and about 80 percent,
a reflectance between about 15 percent and about 85 percent,
a diffuse transmittance between about 5 percent and about 65 percent, or
a direct transmittance less than about 10 percent and another diffuse transmittance greater than the direct transmittance;

locating the first reference object in the digital image;
calculating a pixel scale factor for the digital image based on both measured and known dimensions of the first reference object;
locating the target object in the digital image; and
calculating a dimension of the target object based on the pixel scale factor.
