A measuring system comprises a stand having a base plate and a vertical column fastened thereto, a stand carriage that is movable along the vertical column and having a counter bearing for placing the object, a runner that is fastened to the stand carriage and is movable relative thereto in a guided manner and has an indenter for penetrating the object, having at least one force generation actuator, at least one motion generation actuator, wherein the indenter is coupled to the stand carriage via the actuators. The measuring system further comprises a metrology frame which is fastened to the counter bearing and is supported laterally on the vertical column, a displacement measuring unit for measuring a displacement of the stand carriage and/or the runner with the indenter. The measuring system comprises a force measuring circuit and a displacement measuring circuit both being are largely configured separately from one another.

Measuring system and method for hardness measurement

The aim of the invention is to determine the local quality of surface data (O) extracted from a volume data set (V) by means of a surface determination method. An environment in the volume data set (V) is determined for each surface point of the surface data (O). Using the curve of the grayscale values of voxels from said environment, at least one quality characteristic (Q) is derived which characterizes the quality of the respective examined surface point. The quality characteristic (Q) or each quality characteristic is output together with coordinates of the respective examined surface point as the method result (O').
