Engineering Applications for V-Stars Measurement

Two areas were measured as part of the V-STARS demonstration. Each area had two pipe flanges that required measurement.

The primary objective of these measurements was to determine the centre point of the pipe flanges as well as the coordinates of four bolt holes for each pipe.

Equipment Used

  1. V-STARS S8 INCA3 Camera
  2. Scale Bars
  3. AutoBar
  4. Coded targets
  5. Single dot targets
  6. Edge targets

Measurement Objectives

  1. Demonstrate INCA3 camera use
  2. Determine location of key centre points
  3. Create planes, circles and lines



The necessary targeting for the measurements was very similar for both areas. The targeting used for the first measurement is shown below.

  1. AutoBar for initial coordinate system
  2. Reference coded targets to tie photography together
  3. Two scale bars
  4. Single dot targets
  5. Edge targets
