德國進口3D掃描儀-GOM.用色彩誤差分析圖呈現全尺寸精度的CAV差異比對，將量測對象掃描成密集的點云數據，再進行數據對位、比對分析，然后用不同的顏色呈現整個樣品的誤差值，并產生報表，達到樣品全域檢測的效果。
German 3D scanner - GOM. Uses color error analysis chart to present full-scale precision CAV difference comparison, scans the measured object into dense point cloud data, and then carries out data alignment, comparison analysis, and then presents the error value of the whole sample with different colors, and produces a report, so as to achieve the effect of sample global detection.
