3D virtual sensor
straintest/
Small tags. Precise data.​
​Capture 3D displacement with up to 0.1 mm accuracy using any camera.
How does it work?
Attach
the visual tags
Place Straintest tags on both sides of key structural points such as joints, bearings, or cracks.
Capture
images
Use any phone camera or drone to record the structure at different times.
Upload
and measure
Straintest automatically reconstructs the 3D geometry and calculates displacement between captures.

* Accuracy refers to standard usage with tag spacing below 10 cm and good lighting conditions.
sub-millimeter precision
Our sensor captures subtle shifts and long-term trends with the reliability needed for confident decisions.
For every measurement, Straintest also estimates the accuracy, ensuring full traceability and trust in the results.
Software flexibility. Hardware stability
Straintest uses visual tags to keep measurements stable over the long term.
These tags stay reliable even when the environment changes, so reference points don’t shift. With strong hardware and smart software working together,
Straintest offers clear advantages over traditional sensors.
