Abstract:
1. A scanner system for scanning an object comprising: a frame comprising a support for receiving said object, said support having a rotational axis extending vertically therefrom; a first laser and a second laser attached to said frame and emitting a first beam of light centered on a first illumination axis and a second beam of light centered on a second illumination axis, respectively, said first laser being positioned and oriented such that said first beam of light illuminates at least a first region of said object when received on said support, said second laser being positioned and oriented such that said second beam of light illuminates at least a second region of said object when received on said support, said first illumination axis and said second illumination axis defining an illumination plane and intersecting said rotational axis at a first intersection angle and a second intersection angle, respectively, said first intersection angle being comprised in a first range from about −15 degrees to about −5 degrees or from about 5 degrees to about 15 degrees, and said second intersection angle being comprised in a second range from about −65 degrees to about −55 degrees or from about 55 degrees to about 65 degrees; and a first optical sensor and a second optical sensor attached to said frame and having a first field of view centered on a first sensing axis and a second field of view centered on a second sensing axis, respectively, said first optical sensor being positioned and oriented on one side of said illumination plane such that at least said first region of said object is within said first field of view and said second optical sensor being positioned and oriented on another side of said illumination plane such that at least said second region of said object is within said second field of view.
