LVR and STRobotics Automated Optical Comparator Technology for Bone Screw Inspection

CHICAGO, Illinois (February 14, 2012)  Lakeview Vision & Robotics, of Chicago, Illinois, and STRobotics of Cambridge, UK announce a new technology for the inspection and measurement of bone screws using an automated optical comparator process.

Using a completely digital process, the technology compares images of a screw in inspection to images of a “golden screw” (first article inspection) through an 18 step rotation and, for each comparison, displays a difference result based on a subtraction of the “golden” image. Mechanical variations are compensated through proprietary algorithms. Images are resolved at a resolution of less than .002. Each 18 image inspection takes approximately 2.5 minutes.

The Automated Optical Comparator Technology can be also be used to calculate screw holding power, major and minor diameters, flank angles, and other critical measures.

STRobotics and LVR have a combined 50 years of experience in robotics and machine vision. Learn more about the Automated Optical Comparator Technology at
