1. What’s the difference between the MetroX’s 4 scanning modes?
① Cross Lines: Efficiently captures surface areas and can scan shiny and black surfaces. It’s more efficient than the Parallel Lines mode. (Requires markers for tracking.)
② Parallel Lines: Excellent at capturing fine and complex details at a lower speed. It can also scan dark or shiny surfaces. (Requires markers for tracking.)
③ Full Field: Quickly captures feature-rich objects without makers as well as featureless objects with markers and deals with diffuse or matte materials well.
④ Auto Turntable: Automatically scans objects in single shot mode by controlling the Dual-axis Turntable’s tilt and rotation via Revo Scan 5 MetroX and offers metrology-grade capture of complex objects as well as color scans if required.
2. What’s special about MetroX?
MetroX offers metrology-grade Multi-Line Laser and Full Field Structured Light scanning capabilities for small to medium objects.
① Four scanning modes for optimal object capture: 14 Cross Lines for fast area capture, 7 Parallel Lines for detail capture, Full Field for fast scans, and Auto Turntable for one-click object scans.
② Never second guess the accuracy with a metrology-grade accuracy of up to 0.03 mm.
③ Fast scans at up to 7 million points per second using full-field structured light and up to 800 thousand points per second using multi-line lasers.
④ Free and powerful software for scanning, editing, merging, and other functions.
3. What technology does the MetroX use?
It uses multi-line laser scan and full-field structured light scan.
4. Is Single Shot mode available for MetroX?
Single shot mode is available in Full-field structured light scanning and Auto Turntable modes.
5. What’s MetroX’s volumetric accuracy?
The volumetric accuracy is 0.03 mm + 0.1 mm × L (m). L is the length of the object.
6. Does MetroX have an optical zoom feature?
No, MetroX has a digital zoom.
7. Does the Full-field scanning mode use a laser?
Yes, all scanning modes work with laser projection.
8. Which of MetroX’s four scanning modes has the best accuracy?
In all four scanning modes, the single-frame accuracy can reach up to 0.03 mm, and the volumetric accuracy can reach 0.03 mm + 0.1mm × L (m). When using marker tracking, the volumetric accuracy stays stable. However, cumulative tracking errors may affect the volumetric accuracy when using feature tracking in Full field mode.
9. Does MetroX have a built-in battery?
No, MetroX is powered externally by its power adapter.
10. How do If use the calibration board?
Calibrating your Revopoint 3D scanner using the calibration board to ensure accuracy. Before scanning, it's suggested that the scanner's accuracy be checked using the calibration board after entering the calibration program. Below are the basic steps:
(1) Power the scanner and connect it to a USB 3.0 port on a PC using the USB Type-A to Type-C Cable and Power Adapter that came with your scanner.
(2) Download and install the latest version of Revo Scan 5 MetroX software to your computer and open it.
(3) Place the calibration board on a flat and stable surface and ensure the pattern on the board is clearly visible.
(4) Enter the calibration program. First, scan the QR code to import the calibration board’s information, then check the scanner’s accuracy. If the accuracy check fails, follow the on-screen instructions to complete the calibration.
11. Does MetroX have cooling to maintain accuracy over extended scans?
Yes, MetroX's fans dissipate heat, keeping its temperature stable. Also, both the image sensor and CPU have real time temperature sensors to compensate for small drift sand ensure accuracy.
12. What are MetroX’s PC requirements?

15. Does the MetroX have Wi-Fi?
No, MetroX can only connect to a PC via a USB cable.
16. Does MetroX have an IMU?
No, laser scanning uses marker tracking, which results in more stable tracking and smoother frame stitching.
17. What’s MetroX’s scanning volume?
The recommended scan volume is 10 × 10 × 10 mm - 1000 × 1000 × 1000 mm.
18. Can MetroX scan transparent surfaces?
Scanning Spray is needed when scanning transparent or specular surfaces. Scanning Spray can be purchased from Revopoint Store.
19. Can MetroX scan black surfaces?
Yes, MetroX can scan black objects directly using the Cross Lines and Parallel Lines modes. However, for better detail, scanning spray is recommended. When scanning black surfaces in Full Field or Auto Turntable modes, scanning spray is necessary. Scanning spray can be purchased from Revopoint Store.
20. Can MetroX scan metal surfaces?
Yes, MetroX can scan metal objects directly using Cross Lines or Parallel Lines modes. You can also scan dull metal surfaces directly in Full Field and Auto Turntable modes. However, for very shiny metal surfaces, a scanning spray is necessary when using these modes. Scanning spray can be purchased from Revopoint Store.
21. How does the Auto Turntable mode work?
After connecting MetroX and the Dual-axis Turntable to Revo Scan 5 MetroX, set the number of rotations, the capture interval, the speed, and the turntable’s tilt angle, click “Start,” then wait for the capture process to finish. For detailed instructions, go to the bottom of the Support-Download page on Revopoint’s website to download the latest MetroX Quick Start Guide.
22. What are MetroX's cameras' resolutions?
Both the Depth camera and RGB camera have a resolution of 2 Megapixels.
23. Can I switch scanning modes during a scan?
Yes, but only within the same tracking mode (Marker or Feature Tracking). To do it, click the Finish button, select "Continue", switch to a different mode, and resume scanning. For complex or large objects, use different scanning modes to capture data from various sections, then merge it with Revo Scan 5 MetroX software for a more accurate 3D model.
24. Can MetroX scan the object with electronic components? Will the laser damage the component?
Sensitive electronic components will not be harmed if they are kept at least 200 mm away. It is important to ensure that the components are not positioned directly next to the scanner's laser outlet, as this area has a high energy density from laser emission.
25. Can MetroX scan the details on a small piece of jewelry, such as a ring or a watch face?
Yes, the recommended minimum scan size for MetroX is 10 x 10 x 10 mm.
26. Can MetroX be used to scan people's faces or bodies in any available mode?
It is not advisable to scan the face in any mode, as direct laser exposure to the eyes poses a risk. However, scanning other body parts (excluding the face) at a normal working distance is considered safe. The software offers a real-time distance prompt to assist with this. To perfectly scan a face or body, Revopoint MIRACO Pro, POP 3 Plus, or RANGE 2 is the best option.
27. Can MetroX safely scan people or animals?
Like most industrial laser 3D scanners, the MetroX is unsuitable for scanning humans or animals. When using the MetroX, please avoid looking directly into the laser beam. MetroX is designed to scan small to medium-sized objects. It uses a Class 2M laser projector, which is generally safe for accidental viewing with the naked eye but is hazardous if viewed with optical instruments or looking into the laser beam for a long period. Here are Class 2M laser safety tips:
① Avoid looking directly into it at a close range.
② To avoid retina damage, don’t look directly into the laser beam through optical instruments capable of magnifying it (e.g., telescopes, and camera lenses).
③ To prevent laser reflection, avoid placing reflective surfaces like mirrors or glass in the path of the laser beam.
28. Can MetroX scan an entire car?
Yes, MetroX can scan a car in sections to be merged, but it's difficult. If you want to scan a car quickly and reliably, we recommend getting the MIRACO Plus and using its Photogrammetric Metrology Kit.
29. Will multiple scans of the same surface area be more accurate than a single scan?
When using laser scanning modes (14 cross-line or 7 parallel-line), repeatedly scanning the same surface area is essential because scanning multiple times from different angles helps the model go green, which means a higher-quality model. Avoid scanning the same area multiple times in Full-field Structured Light mode. With a capture rate of up to 7 million points per second, repeated scans can lead to more errors rather than improved accuracy.
