Abstract

The direct contour mapping (DCM) algorithm, which was proposed and developed by the authors, is effective for automated contour mapping around a peak of a solid body. For mapping of a solid body with multi peaks, the faculties for recognizing the shape of contour lines and for deducing the position of independent peaks should be needed. The DCM system in the present paper consists of a coordinate measuring machine (CMM), a personal computer (PC) and an engineering-workstation (EWS). With the DCM algorithm, the PC controls the CMM to measure a contour line of the solid body, then the shape of the measured contour line is represented by a chain code and sent to the EWS. The EWS analyzes the chain code data to recognize the shape of the contour line. The result of recognition is sent back to the PC, where the PC deduces the presentation and position of independent peaks. Experimental results of measurement for solid bodies having three and more peaks are shown.
