Abstract

A laser frame tracer (12) including a laser measuring unit (20) with a laser (36) and one or more cameras (38, 40) for optically measuring dimensions of eyeglass frames (10). A frame carrier (22) is provided for moving the eyeglass frames (10) through a laser line emitted by the laser (36). The frame carrier (22) includes a linear carriage (44) and a rotary carriage (88). Movement of the linear carriage (44) and the rotary carriage (88) are controlled by an on-board computer (116) which collects image data from the one or more cameras (38, 40). Image data is processed to determine a 3D model from which selected dimensions for the eyeglass frames (10) may be measured. The dimensions may be stored in a cloud database for access by others in cutting lenses to fit the eyeglass frames (10).

Claims

1. A laser tracer, comprising:

a laser measuring unit including a laser and a camera, said laser adapted to emit laser light and said camera adapted to record images of reflected laser light;

a moveable platform with said laser measuring unit scanning an object with said laser light; and

a data processing unit adapted to store said images from said camera.
