Generate Point Cloud Model

There are two ways for you to generate a point cloud model in Matching Model and Pick Point Editor: from images acquired by the camera, or from an imported CAD file.


icon1 Generate from Images Acquired by the Camera

This feature first acquires a depth map of the background and one with the target object in it, and then generates a point cloud of the target object through comparing the two depth maps.

Hint

This feature is available only when the opened project contains the Capture Images from Camera Step, AND the Camera Settings parameters of this Step are fully configured.

The procedure differs depending on whether you are using a real camera or a virtual camera. Click on the options below for detailed instructions.


icon3 Generate from imported CAD files

If you already have the CAD model file of the target object, you can import this file into Matching Model and Pick Point Editor, and generate a point cloud model from the CAD file.

Hint

Currently, only STL format is supported.


Hint

Other than generating point cloud models through the methods described above, you can also import existing point cloud files in PLY format directly by clicking on icon2 in the Toolbar.

The following are some actions you can take once you have generated a point cloud model:

  • Save all the files in the Lists: click on File ‣ Save or use the shortcut Ctrl+S.

    Hint

    Files are save to the following directory: Project Folder/resource/model_editor.

  • Delete a point cloud model: right-click on the point cloud you wish to delete in the Model Files List, and select Delete in the pop-up menu.

  • Toggle the visibility of a file: click on EyeIcon to the right of the file name will make the file invisible in the Visualizing Space. Clicking again makes the file visible.

  • Show the bounding box: select a file in the Files List, and then check the box in front of Show bounding box below the CAD Files List.

  • Change the display color of a point cloud: select a point cloud model in the Model Files List, double-click on the white rectangle next to Cloud color below the CAD Files List, and then change the color in the pop-up window.

    Hint

    The display color of an imported color point cloud cannot be changed.


Now that you have a point cloud model, you can start editing it to meet your actual needs. Please click on Next in the lower right for a detailed instruction for editing a point cloud model.
