¶ 7. Your First Scan
¶ 7.1 VCSEL Rapid Scan
In this example, RANGE 3 is used to scan a large sculpture to introduce the operation process of the VCSEL Rapid scanning mode.
¶ 7.1.1 Start Scanning
¶ Create a New Scan
Click"New Scan" on the File page.
① Select "Feature" for the tracking mode and select "VCSEL Rapid" for the scan mode.
② Name the scan file and click "Confirm" to enter the scanning interface.
¶ Scan Settings & Scan Control
① Set Accuracy to "High Accuracy" by default, select "Dark/Black" for Object Type, and then configure Scanning Distance as needed.
② Enable Color Scanning if the color model is needed.
③ Enable Base Removal, Object Segmentation, or Remove Background as needed to reduce unnecessary object interference.
④ Check the object position in the left camera preview window to ensure the object is within the camera's field of view.
⑤ Adjust the depth camera exposure to minimize red or blue coloring on the object surface in its preview window. Gray is preferred.
⑥ Adjust the scanner‑to‑object distance to ensure the color bar on the distance histogram shows green.
⑦ After parameters are configured, click "Scan".
⑧ You can pause during scanning and view the scanning progress in real time in the object scan status pane. Click "Scan" to resume if the scan is incomplete.
¶ 7.1.2 Finish Scanning
You can refer to the following criteria to determine if scanning is complete:
- Data completeness: Ensure key areas are fully captured and check for missing data on model boundaries and contours. (Small holes can be manually filled during post-processing.)
- Data registration quality: Ensure no misalignment, shifting, or other anomalies are present in the data.
- Point cloud quality: Ensure the model surface is free from excessive noise, spikes, or uneven density (over-dense or sparse regions) that could degrade model quality.
After you confirm that no such issues exist, click "Complete" to finish the scan. If the model is incomplete, click "Scan" to resume.
¶ 7.2 Laser Line Scan
Only RANGE 3 Pro supports the Laser Line scanning mode.
¶ 7.2.1 Preparation Before Scanning
¶ Handle the Object
- Set up a marker environment for scanning in Marker or Global Marker tracking mode.
Do not use too many markers and ensure that at least 5 markers are placed irregularly per scanned frame.
For optimal accuracy, attach the markers to flat surfaces rather than curved ones. Do not use cushioned pads or soft cloths with pre‑applied markers.
You can also use the Marker Block Kit to create a more ideal and complete scanning environment.
Marker Block Kit Quick Start Guide
- Use Scanning Spray
For transparent or specular objects, such as glass, stainless steel, and electroplated surfaces, both the laser line scanning and structured light scanning require scanning spray.
For dark reflective or metallic reflective surfaces, such as black paint and machined aluminum alloy, the laser line scanning can be performed without spray.
Note: Scanning spray can be purchased from Revopoint's online stores.
For detailed object processing instructions such as how to use markers, please refer to Scanning Tips--Handle Objects Before Scan.
¶ 7.2.2 Start Scanning
¶ Create a New Scan
Click "New Scan" on the File page.
① Select "Marker" or "Global Marker" for the tracking mode and select "Laser Line" for the scan mode. For more details about mode selection, please refer to Tracking Mode & Scan Mode.
② Name the scan file and click "Confirm" to enter the scanning interface.
¶ Scan Settings & Scan Control
① Enter the scan interface. Set Accuracy to "High Accuracy" and select "Metallic Shiny Object" for Object Type.
② Configure the target point distance. A larger value enables faster scanning, while a smaller value produces a finer model at a relatively lower scanning speed.
③ Adjust the exposure and laser brightness of the depth cameras to ensure that the laser lines are clearly visible in the depth camera preview window.
④ Adjust the scanner‑to‑object distance to ensure the color bar on the distance histogram shows green.
⑤ After parameters are configured, click "Scan."
⑥ You can pause during scanning and view the scanning progress in real time in the object scan status pane. Click "Scan" to resume if the scan is incomplete.
¶ 7.2.3 Finish Scanning
You can use the following criteria to determine if scanning is complete:
- Data completeness: Ensure key areas are fully captured and check for missing data on model boundaries and contours. (Small holes can be manually filled during post-processing.)
- Data registration quality: Ensure no misalignment, shifting, or other anomalies are present in the data.
- Point cloud quality: Ensure the model surface is free from excessive noise, spikes, or uneven density (over-dense or sparse regions) that could degrade model quality.
Note: In Laser Line scanning mode, the quality map gradually turns blue as more frames are rendered. A fully blue quality map indicates high-quality scan data. Therefore, we recommend that you scan the object from multiple angles and directions until the entire model surface turns completely blue.
After you confirm that no such issues exist, click "Complete" to finish the scan. If the model is incomplete, click "Scan" to resume.
¶ 7.3 Outdoor Scan
Both Laser Line and VCSEL Rapid modes support outdoor scan.
Avoid scanning in rainy or windy conditions. Moisture may damage the scanner or impair data accuracy due to wet object surfaces.
¶ 7.4 More Tips
For improved scanning results, you can review and configure suitable parameters prior to scanning. Parameter settings directly impact model completeness, definition, and post‑processing efficiency. Refer to Revo Scan 6 User Manual - Scanning Parameters Settings for guidance on detailed settings.

¶ 8.3 AI Object Segmentation and Tracking Function
Object Segmentation: Uses AI object recognition and tracking technology. After selecting the target object region, the software can continuously track that region during scanning, automatically remove irrelevant environmental point clouds, and output independent object point cloud data. For details, see Revo Scan 6 User Manual - Object Segmentation.
Remove Background: Uses AI background recognition and filtering technology. After selecting the background area to be removed, the software can continuously ignore that area during scanning and automatically retain the target object's point cloud. For details, see Revo Scan 6 User Manual - Remove Background.
¶ 8.4 3DGS Real Modeling Function
3DGS: Uses 3D Gaussian Splatting reconstruction. The system generates a Gaussian model based on point cloud and RGB scan data for improved surface detail fidelity. This feature can only be used after mesh reconstruction.
