Abstract:
1. A surface scan measuring device, comprising: a scanning probe having a measuring piece brought into contact with or close to a workpiece surface, and a detection sensor for detecting the relative position between the measuring piece and the workpiece surface, the scanning probe scanning the workpiece surface in the state in which the relative position between the measuring piece and the workpiece surface is kept in a preset reference position range; a motion section which relatively moves the scanning probe along the workpiece surface; a drive sensor for detecting drive amount of the motion section; and an analysis section which analyzes a profile of the workpiece based on detected values by the detection sensor and the drive sensor; wherein the analysis section is provided with a compensation table stored with compensation data to correct detected values obtained by the detection sensor for respective directions along which the measuring piece measures the workpiece surface when the scanning probe scans the workpiece surface.
