Scan 3d Calibration Offset#

The Scan 3d Calibration Offset feature allows you to add an offset to the distance measured to compensate for differences between the measured and the actual distance of the target.

运作原理#

The offset specified by the Scan3dCalibrationOffset parameter is added to the radial distances the camera measures. The camera transforms the radial distances into x, y, z coordinates in a Cartesian coordinate system whose origin lies in the camera's optical center.

即： Scan3dCalibrationOffset parameter can be used to manually correct a temperature-dependent drift.

信息

由于偏移量已添加到径向距离中，因此无法用于平移坐标系的原点，即，不能用于向 z 坐标添加恒定偏移量。
特别是，请勿通过这种做法来尝试将相机坐标系的原点从光学中心移动到相机外壳的前部。否则会导致测量错误，造成平坦表面看起来呈现弯曲的效果。
