Patent ID: 7315794

Claim:
A process, comprising the following steps: a. employing a first and second projection source to place a first reference point and a second reference point on the trunk of a tree, such that projection paths of said projection sources are parallel to one another and substantially perpendicular to the longitudinal length of said tree, and wherein an actual distance between said first reference point and said second reference point is a known distance, “A 1 ”; b. employing a third projection source to place a third reference point on the trunk of said tree, wherein said third projection source is positioned at a known angle, “{acute over (α)} 1 ”, relative to said first projection source and positioned a known actual distance, “A 3 ”, from said second projection source; c. capturing an image of that portion of the trunk of said tree having said reference points placed thereon; d. measuring on said image an image distance, “D 1 ”, between said first reference point and said second reference point; e. measuring on said image an image distance, “D 2 ”, between the left outer boundary and the right outer boundary of the trunk of said tree; f. calculating an actual distance, “A 2 ”, between a left outer boundary and a right outer boundary of the trunk of said tree as follows: A 2 =[(D 2 ÷D 1 )( A 1 )]; g. recording to a file record at least one of: i) said distance A 2 ; or ii) a tree measurement derived from said distance A 2 .
