Capturing High Quality Point Clouds

The basic approaches to getting high-quality point clouds are as follows:

• Presets

• Capture Assistant (GUI & API)

If you are not satisfied with the point cloud quality using these approaches, continue reading this tutorial.

Prerequisites

We recommend starting by visiting Camera Settings to learn about the exposure variables and available filters. The articles which we recommend as a prerequisite for this tutorial are:

• Vision Engine

• Acquisition Settings

• Processing Settings

Basic and generic tutorials

The procedure to get high-quality point clouds can be divided into a couple of steps:

• Working Distance and Camera Positioning
• Getting the Right Exposure for Good Point Clouds
• Adjusting Filters
• Optimizing Color Image

Note

If you are looking for a set of settings that provide good 3D point clouds for different scenes, check Zivid presets

In some cases we might want higher quality data on certain pixels, this is covered in:

• How to Get Good 3D Data on a Pixel of Interest

Advanced tutorials

We will also cover some more advanced topics such as specifically dealing with highlights and lowlights, and considering environmental factors, such as ambient light and choice of background.

• Dealing with Highlights and Shiny Objects
• Dealing with Strong Ambient Light
• Dealing with smooth 3D edges
• Depalletization - Imaging at Large Distance
