# Improving point cloud color quality

## Issue description

The post-processed cloud has vague colored patches in large areas. Very few details can be observed from the Point cloud, only shapes.

This could be because not enough panorama images were captured during the scanning. The processing software relies on the captured panorama images for color information. If you look at the example, you can see that there were no images in the middle portion of the scan (red dots mark the capture locations, the yellow line is the trajectory during the mapping). Therefore, the software was re-using the same color from the previous area, which created these vague color patches.

## Troubleshooting procedure

There is no way to rectify this other than remapping. When remapping, use the [automatic panorama triggering](https://knowledge.navvis.com/docs/triggering-the-cameras?highlight=automatic%20panorama%20triggering#smart-triggering-of-cameras) setting.

1. Tap the settings icon and set the automatic triggering parameter to 1.5-2 meters.
2. When you hear the beep reminding you to stop, stand still and the NavVis device will automatically capture the image.

### FAQ

#### What issue is described with the post-processed cloud?

The post-processed cloud has vague colored patches in large areas, with very few details visible, only shapes.

#### What could cause the vague color patches in the point cloud?

The vague color patches may be due to not capturing enough panorama images during the scanning process.

#### How does the processing software use panorama images?

The processing software relies on the captured panorama images for color information.

#### What should I do if there are areas without captured images?

If there are areas without captured images, the software may reuse colors from previous areas, leading to vague patches.

#### Is there a way to fix the vague color patches without remapping?

No, the only way to rectify this issue is by remapping.

#### What setting should I use when remapping?

When remapping, use the automatic panorama triggering setting.

#### What is the recommended automatic triggering parameter for remapping?

Set the automatic triggering parameter to 1.5-2 meters.

#### What should I do when I hear the beep during remapping?

When you hear the beep, stand still, and the NavVis device will automatically capture the image.

A Point Cloud is as a collection of data points in space that typically represent the external surface of an object or environment. Point clouds are used in various applications, including 3D scanning and mapping, and can be visualized and manipulated using Navvis IVION. You can perform actions such as panning, orbiting, cleaning up noise, cropping, and downloading data in formats like .e57 or .ply. The resolution of point clouds processed with NavVis Software achieves a minimum detail of 5mm, indicating the precision of the spatial data points.
