scanCONTROL laser scanners also detect large measurement areas with high resolution and are ideal for use in CMMs due to the low sensor weight. Measurement data acquisition is very fast with measuring rates up to 10 kHz.
measurement areas at high resolution and are ideal for use in CMMs due to the low sensor weight. Measurement data acquisition is very fast with measuring rates up to 10 kHz. As a result, a complete 3D point cloud is available, which allows precise evaluation, quality inspection as well as further processing. The scanCONTROL laser scanners are based on the latest GigE Vision and GenICam standards and can therefore be integrated in a wide range of image processing environments. The 3DInspect software is a powerful tool for parameter setting, evaluation and output. Among other things, laser scanners are used for prototype scanning. The sensor can be guided by a robot arm or integrated in a measuring table. The scanner measures the component while being moved over the component from all sides. Taken from multiple directions, the user obtains a 360° image. A software solution transforms it into a complete 3D point cloud within an extremely short time. To enable high-precision measurements, the measurement data must be perfectly synchronised with the measurement position. Conventional sensors are often triggered externally and detect the profile with a time delay that causes inaccurate position data. The scanCONTROL laser scanners from Micro- Epsilon, on the other hand, offer a special CMM trigger for this purpose. This is a parameter output optimised for CMMs. The sensor can therefore send trigger pulses in the middle of the exposure time and thus assign the profile to an exact measuring position. Fine tuning is also possible, for example, to compensate for run times of the pulse in the cable. As scanCONTROL laser scanners are available with different measuring ranges, both large and small objects can be detected. The captured 3D point clouds can be compared with existing CAD models to make any discrepancies obvious.
