  • Refresh Point Cloud

    Refreshing the point cloud will trigger the camera to perform one data acquisition and update the point cloud in the 3D display area.

  • ROI Size Display

    The length, width, and height dimensions of the current ROI are displayed in the ROI data bar.

  • ROI Adjustment

    • Step size adjustment: Select the step size in the dropdown bar to the right of the step size. The step size affects the offset when adjusting ROI in a single step.

    • Rotation, translation, and stretch adjustment: Click the corresponding +/- buttons.

Adjustment Example

Using the illustration in the operation steps as an example. The adjustment process is as follows:

  1. Set ROI Length and Width

    1. Click Z to switch to the +Z view.
