Positioning Correctly

The 2D camera and the projector have an angle with respect to the center axis. This should be considered if it is desired to have the camera perpendicular to the scene.

If possible, mount the camera at a slight tilt angle to avoid reflections and interference from the background. This also frees up space above the scene for easier access for tools and robots. Check out available Zivid mounts.

Ambient light might reduce performance. Consider blocking direct light affecting the scene.

Note

Camera tilting is more important if the scene contains specular surfaces.

For bin-picking applications, place the Zivid camera projector above the back edge or above the rear corner of the bin (see images below). Pan and tilt it so that the 2D camera is looking at the center of the bin. The projector rays should not fall on the inner surfaces of the two walls closest to the projector; they should almost be parallel to those two walls. Mounting the camera this way minimizes inter reflections from the bin walls.

Mount the camera to minimize occlusion if you have bin dividers and/or multiple bins in your scene.

This article should help you make the right decisions regarding purchasing or designing, integrating, and installing accessories and equipment for robot mounting.
