Hand-Held Fastener Surface Measurement

ABSTRACT: There is a significant need for a handheld device that can do fastener flushness measurement and countersink measurement. In this proposal, X-wave Innovations, Inc. (XII) propose a handheld, non-contact, three-dimensional (3D) measurement system (called SnapSCAN). The SnapSCAN utilizes a unique design based on our 3D scanner that has a MEMS laser projector and a split lens 3D sensor, allowing much faster and accurate measurements than any other handheld devices on the market. The key innovation of the proposed SnapSCAN is the integration of 3 state-of-the-art technologies (including 3D scanning and measurement technology, MEMS laser color image projection technology, and ultra compact computer technology) into one compact, handheld device. It is a true standalone system that requires neither additional assistant component for 3D data stitching, dedicated computer for calculation, nor wired power supply. It can replace two different gauges on the market: Protrusion/Flushness Gauge (Analog or Digital) and Countersink Gauge (Analog or Digital). It can provide high accuracy comprehensive analysis results. The system startup time is only a few seconds. There is no need for any pre-setups such as system calibrations. The measurement time for a fastener can be less than one second. BENEFIT: The key advantage of the proposed handheld SnapSCAN is the non-contact nature, which eliminates the possibilities of damaging the fastener and surrounding surfaces during scanning and measurement, improves accuracy, and eliminates sources of human error. The image guided quick measurement can interactively guide the operator to find the optimal location for the scanner, make measurement and show the results in real-time. By whole surface measurement, it can provide accurate and comprehensive results that are impossible by other tools. The measurement results can be interactively displayed and be instantly saved to local hard drive or to wireless network storages.
