We describe the use of an automated co-ordinate measurement machine (CMM) directly or in concert with a three-axis robot arm to map the distortion of a 3D structured light scanner's field of view. This enables us to compare the claimed accuracy and resolution of different structured light scanners. In addition, we can also use the distortion mapping to generate a correction mechanism to improve the performance of the scanner. We present the results of experiments obtained using this novel approach on three commercially available 3D scanners.

映射和校正 3D 结构光扫描仪的失真

我们描述了直接使用自动坐标测量机 (CMM) 或与三轴机械臂配合使用来绘制 3D 结构光扫描仪视野的失真。这使我们能够比较不同结构光扫描仪声称的精度和分辨率。此外，我们还可以使用畸变映射来生成校正机制，以提高扫描仪的性能。我们展示了在三个商用 3D 扫描仪上使用这种新方法获得的实验结果。
