In V-STARS/S Mode, one camera is used to take images of an object that is fitted with photogrammetry targets.
By automatically measuring points of the images, V-STARS automatically recreates the network geometry of these images and the points.
We call this "S-mode". It is also called off-line photogrammetry because the calculation of the point coordinates is performed by V-STARS only once the images are taken.
The highest measurement accuracy and versatility attainable with V-STARS is obtained with the S Mode system using GSI's INCA4 camera.
V-STARS has been fully tested and validated in accordance with the VDI/VDE 2634 standard for optical 3D measurement systems.
There are four S-Mode system configurations of V-STARS:
V-STARS/M INCA4 using the INCA4 camera,
V-STARS/N PLATINUM, V-STARS/N GOLD and V-STARS/N SILVER systems using the N series cameras.
They are all portable and comprises of a high accuracy and calibrated digital camera, a lap top computer, V-STARS software, and accessories. The 3D measurement accuracy today ranges from 10 µm + 10 µm/m to a maximum of 4.5 µm + 4.5 µm/m, corresponding to 0.0225mm @ 4m or 1:200,000.
V-STARS/S has the inherent advantages of photogrammetry. The V-STARS measurement is immune to vibration and movement; the camera can be operated hand-held from MEWPs (Mobile elevating work platforms),
cranes and unstable platforms; image process is extremely fast; ultra-fast wireless transmission of the recorded images is available; and the systems fit into two small cases that can travel as carry-on luggage.
In addition, multiple cameras used simultaneously in S-mode for the measurement of both dynamic and static objects.
