V-STARS offers attractive and unique advantages over alternative 3D measurement techniques. V-STARS has been fully tested and validated in accordance with the VDI/VDE 2634 standard for optical 3D measurement systems.

High accuracy


Absolute accuracy to 5µm + 5µm/m of the size of the object (0.055mm on a 10m object) is attainable with the single camera V-STARS/N-Platinum system, whereas the N-Gold and N-Silver systems are capable of measurement accuracy of 7µm + 7µm/m and 10µm + 10µm/m of the size of the object of the size of the object accuracy, respectively.

The dual camera, real-time V-STARS/DynaMo-D5 measurement system produces an accuracy of 14µm + 14µm/m of the size of the object (0.15mm on a 10m object).

The V-STARS process is totally non-contact, which makes it ideal for the measurement of both delicate items that deform when touched, and objects in hostile environments such as solar vacuum chambers and nuclear plants. 

Fast results

Single camera V-STARS systems produce results on site within minutes of completing photography of the object. Results are available instantly, in real-time with the multi camera on-line V-STARS/DynaMo systems


V-STARS is highly flexible and adaptable, and is routinely used across a wide range of applications, exemplified by dimensional characterization, part inspection, deformation measurement or even part adjustment. 


V-STARS is battery operated and highly portable, and can be transported to remote locations, generally as carry-on luggage comprising a camera case and laptop computer. The system is thus ideal for complete on-site measurement operations.

Minimal temperature effect

As the photography is generally completed in less than 10-15 minutes, the effect of thermal expansion/contraction on the object being measured is minimized. 

Immune to vibration

V-STARS operates in unstable environments, including upon vibrating or unstable floors, man lifts, cranes and ladders. Additionally, the object itself can be vibrating or moving during the measurement without affecting the results, though it must retain its shape during the photography. 

Versatile in confined spaces

The system is sufficiently versatile to operate in even the most confined spaces and challenging line of sight environments.

High data rates

V-STARS in single camera mode is capable of measuring thousands of points in the same amount of time it takes to measure hundreds.

Thermal vacuum chamber

With I-CAN, GSI's state-of-the-art INCA3 and DynaMo cameras can operate in thermal vacuum environments, yet still produce the same high accuracy as V-STARS operating in normal conditions 

Target projection operation

The PRO-SPOT target projection system enables the measurement of thousands of points on a surface without applying a single target. PRO-SPOT is suited to rapid surface measurement for inspection or adjustment purposes

Proven Track Record

GSI has established itself internationally over three decades as the premier system manufacturer and service provider in high accuracy, image-based 3D industrial coordinate measurement. V-STARS has been fully tested and validated in accordance with the VDI/VDE 2634 standard for optical 3D measurement systems.
