3D Scanning

Tuning parameters under 3D Scanning can optimize the point cloud quality by improving the images used for acquiring depth information. Please see 3D Scanning for details.

Point Cloud Processing

Tuning parameters under Point Cloud Processing can optimize the point cloud quality by optimizing the processing of the obtained data.

Cloud Smooth Mode

• This parameter sets whether and how strongly the point cloud surface smoothing algorithm is applied. The options and descriptions are listed below.

• Options:

  • Off: Apply no smoothing algorithm to retain object details as much as possible.

  • Weak: Apply weak smoothing. Keep more details and apply less smoothing.

  • Normal (default): Apply moderate smoothing. Balance between smoothness and detail preservation.

  • Strong: Apply strong smoothing. Keep fewer details and apply more smoothing.

  Hint

  Intensity of smoothing: Off < Weak < Normal < Strong.

Cloud Outlier Filter Mode

• This parameter sets whether and how strongly the point cloud outlier removal algorithm is applied. The options and descriptions are listed below.

• Options:

  • Off: Apply no outlier removal. Keep all noise.

  • Weak: Apply weak outlier removal. Remove a small amount of noise. Produce more accurate and complete edges.

  • Normal: Apply outlier removal. Remove all noise detected. Mild edge erosion may occur.

  Hint

  Intensity of outlier removal: Off < Weak < Normal.

• Point Clouds under different intensities of outlier removal:

  Off	Weak	Normal

Fringe Contrast Threshold

• This parameter sets the signal contrast threshold for selecting valid pixels. Pixels with contrast less than this threshold will be ignored. A higher value means filtering more image noise but may remove point clouds of dark objects.

• Value range: 1 to 100 (Default is 3)

• Usually, the default value 3 works well but you can increase the value for images with heavy noise.

  Point clouds obtained with different values of Fringe Contrast Threshold:

  3	15	30

Hint

• Usually, setting Cloud Smooth Mode and Cloud Outlier Filter Mode to Normal and setting Fringe Contrast Threshold to 3 will help obtain satisfactory point clouds.

• If after tuning the parameters, the point cloud is still not satisfactory, please save the raw data of the camera and save the images via File ‣ Save Raw Data of Camera and File ‣ Save Images, and contact the support team.

Depth Range

• The upper limit and the lower limit of depth range are to set the interested range of depth on the depth map and ignore the parts of the depth map with depth values beyond the depth range.

• 1 to 9,999 mm

• Point clouds under different depth range settings:

  Too large	Moderate	Too small

Hint

Please set an appropriate range to select the parts that are relevant to your projects. The range should not be too large or interference may be introduced. Nor should it be too small or the key parts of the point cloud may be missing.

3D ROI

• This parameter is an entry for setting the ROI used in generating depth maps and point clouds. Pixels outside the ROI will not be used to generate depth maps and point clouds.

  Click on Edit to open the ROI setting window.

  Click on Apply to finish setting.
