Problem
Sensors used for 3D object scanning must undergo a calibration and verification process that requires moving the sensor and acquiring data along pre-set trajectories.
The accuracy of this process is critical to guarantee the required measurement precision (0.1mm in our case); therefore, controlling environmental conditions and process repeatability is crucial for sensor mass production.
Solution
ACSENS is a system for automatic calibration of sensors dedicated to high-precision three-dimensional scanning.
A 6-axis cobot moves the sensors along pre-programmed trajectories around a calibration target, ensuring acquisitions at optimal positions for continuous comparison between real data and theoretical models.
The calibration is adaptive and fully automated, continuing until sufficient precision is achieved with errors reduced below pre-set thresholds, so that highly reliable and repeatable results are systematically achieved.
ACSENS ensures rigorous control of environmental conditions by integrating a target self-centering system, calibrated lighting, and continuous monitoring of temperature and humidity.
All calibration data and process logs are automatically stored and transmitted to remote servers, ensuring security, traceability, and easy access to information.
