You can now focus on a specific section of your 3D point cloud based on the selected 2D output. This enhancement makes it easier to identify objects and improve spatial awareness across the entire scene.

Introduces the ability to adjust camera field of view and distance for better focus. Enables quicker identification and annotation of specific objects.

Overview

Previously, users had the ability to color the point cloud based on camera distance, but the process lacked precise control over specific areas of interest. There was no way to seamlessly integrate camera field of view adjustments with point cloud visualization. This feature was needed to provide more control and flexibility, allowing users to focus on smaller regions within their 3D point cloud and improve accuracy when identifying objects. By combining both the camera field of view and distance, the "Region of Interest" feature enhances precision and streamlines the annotation process.

What's new?

This feature helps the user focus on specific areas of the 3D point cloud, using the 2D video output as a reference. It reduces cognitive noise around the image and allows the user to focus on a particular area of interest needed to annotate.

Full Point Cloud View (No Emphasis)

In this example, both Camera Field of View and Camera Distance are disabled, allowing the entire point cloud to be visible, and when zooming in on the 2D frame, there is no emphasis on any specific section of the point cloud.

 

 

Focused Point Cloud with Adjustable Range

In this example, when Camera Field of View and Camera Distance are enabled, the point cloud is adjusted to match the zoomed-in section of the 2D image. This functionality also works without Camera Distance enabled, but when Camera Distance is activated, it defines a range of frames, displaying the point cloud from the current frame up to the specified frame.

 

 

How to use it?

1. Enabling "Camera Field of View"
Go to Settings and click the new Region of Interest tab. Enable Camera Field of View to highlight the section visible in the 2D output. As you zoom in or out, notice how the point cloud adjusts dynamically, narrowing or expanding based on the 2D view. The 2D and 3D views stay synchronized, making it easier to focus on specific objects.

2. Adjusting "Camera Distance"
In the Region of Interest tab, enable Camera Distance to control the depth of the colored point cloud. Use the text box to enter a number and set a distance threshold, removing points beyond the selected range. The 3D point cloud updates accordingly, refining visibility based on the set distance. This adjustment works seamlessly with zoom, helping you focus on relevant objects.
