Visual inspection device and process

A system for inspection of a part comprising:

• means for mapping a first portion of the part;
• means for mapping a second portion of the part;
• means for defining a first reference coordinate corresponding to a first reference point located on the first portion of the part;
• means for defining a second reference coordinate corresponding to a second reference point located on the second portion of the part;
• means for determining the number of coordinates between the first reference coordinate and the second reference coordinate;
• means for calculating a constant corresponding to third portion of the part, wherein the third portion of the part is not mapped;
• and
• means for adding the constant to the number of coordinates between the first and the second reference coordinates.

A system for inspection of a part comprising:

• a computer;
• a first camera connected to the computer and having a first field of view;
• a second camera connected to the computer and having a second field of view;
• and
• a light source located such that the part is between said first camera and said light source;
• wherein the first field of view includes a first portion of the part;
• wherein the second field of view includes a second portion of the part;
• wherein the computer digitizes the first field of view to define a first digitized field of view;
• wherein the computer digitizes the second field of view to define a second digitized field of view;
• wherein the computer assigns a set of coordinate address values, one to each coordinate of each of the digitized fields of view;
• wherein the computer assigns a set of coordinate image values to each coordinate of each of the digitized fields of view;
• wherein the computer pastes the first and the second digitized fields of view together as if the first and second digitized fields of view were separate halves of the one total field of view, whereby a pasted digitized field of view is defined;
• wherein the distance in coordinates between any coordinate of the first digitized field of view and the second digitized field of view is corrected by a correction factor;
• and
• wherein the correction factor is determined from the distance between the first camera and the second camera.
