Hovermap can create world-class true color point clouds, providing additional context for visualization and analysis. This builds on the incredible data that Hovermap already produces to create rich, accurate digital twins and surveys.
The colorization feature uses a GoPro camera that attaches to Hovermap. This modular approach allows you to attach the camera only when colorized scans are needed.
You can use the perspective-based GoPro Hero cameras or the 360° field of view GoPro Max for colorization. Emesent recommends using the 360 GoPro Max when capturing a larger amount of colorization data. However, the perspective Hero cameras may be more suitable in certain cases.
GoPro Hero cameras have a restricted field of vision, which means only the area within the camera's view will be colorized. To ensure optimal results, it is essential to point the GoPro directly toward the specific subject you are interested in capturing.

Tips for using colorization
Use the recommended settings for your GoPro.
Ensure that the GoPro lens is clean and free of dust and other material.
Only points that fall into the camera’s field of view will be colored.
Keep the Hovermap still for the first 10 seconds after the LiDAR starts to spin, then perform at least three vigorous side-to-side synchronization rotations.
If using a GoPro Hero perspective camera, we recommend using a “painting” motion to capture as much of the area as possible.
Minimize vibrational movement to avoid blurry video frames. Move slowly and avoid sharp turns and jerky movements.
Keep your scanning distance to around 20 m / 65 ft. If you go further than this, the matching of the pixels and points deviates, and you will see a slight decrease in quality.
It is important to have sufficient lighting in the area being colorized. While Hovermap can operate in complete darkness, the GoPro requires adequate lighting.
Spend time on subjects to be colorized to improve colorization quality.
For the best results, make sure to capture each object in the scene from multiple angles using the GoPro camera.
Limit any movement of objects in the scene being captured, including people walking through the frame.
Avoid tampering with, or removing, the GoPro mounting bracket. Its exact position has been accounted for during the calibration process.
Only use colorization when necessary as scanning and processing colorized scans can take longer than a normal scan.
Each GoPro is calibrated to a specific Hovermap. Do not use a GoPro that has not been calibrated to your Hovermap. Contact your local reseller or Customer Success if you need a new GoPro.
To help keep your scans and videos in sync, hold your phone in front of the camera after starting the scan and the recording to capture the name of the current scan in the Hovermap Web UI.
