Creation, configuration and calibration of a device

This small tutorial will guide you through the creation and calibration of two Orbbec Femto Mega cameras.

To calibrate devices, we advise you to start by deactivating the crop region. This allows you to freely move your point clouds in the 3D space without losing points due to the crop region.

To create a camera, go to the “Cameras” tab of the side bar and press on the “+” button. A menu item should be created. The Orbbec device type should be selected by default.

If Orbbec cameras are connected to your network, the IP dropdown should already contain their IP addresses. If you just plugged them in, wait a moment for them to start up and for Carto’s auto discovery process to find them. Selecting an IP should connect the camera to Carto and a point cloud should appear.

Start by trying to align the floor, walls or an easily identified object of your space. To help with the visualization, you can use the solo and mute buttons of each device. Orthographic views are very useful to align walls and floor.

For your second camera, try to align walls, floors or another object to the point cloud of your first camera.

You can then re-activate the crop region. Click on the handles of the crop region to get a gizmo that allows you to resize and move it.

The crop region allows you to crop out the floor, walls and other object to be able to get points only when someone is moving in the space.

Note that it is possible to select multiple objects with Ctrl+Click. This can help you to change the position of the cameras without losing your calibration.
