German automation company Visutronik GmbH has developed a laser scanning device to measure surface soil samples for subsequent geometric analysis: roughness, surface type expansion (e.g. earthworm courses), etc. The core of the measuring device is the scanCONTROL 2700-100 laser scanner. This sensor projects a vertical laser line from the top to the bottom of the soil sample. The integrated camera system views the sample from another angle, resulting in a classic triangulation approach. To scan the sample surface, the laser scanner moves along a linear axis horizontal to the sample. Every 0.1 mm a profile measurement is carried out. A large number of profiles form a relief, which the software uses to calculate the elevation profile. The associated scanCONTROL 3D-View software configures the laser scanner, visualizes and stores the acquired 3D data. The relief data is evaluated using commercially available software (e.g. ArcView, Surfer, Saga).The combination of laser scanner, linear axis, motor control and software makes this solution suitable for continuous/inline industrial applications. You can, for example, automatically check the flatness of punched parts by using software that is tailored for each application.
