7. Guide for Scanning

Settings before scan:

Recommended objects Size: 15x15x15 cm³ ~ 200x200x200 cm³

Object: Normal, Face and Body

• Normal: Designed to scan normal objects. It is divided into large object (50x50x50~200x200x200 cm³), medium object (25x25x25~50x50x50 cm³) and small object (15x15x15~25x25x25 cm³). It is recommended to use a PC to scan small objects better. The CR-Scan Ferret (Pro) is ideal for medium and large sized object scanning. If you are new to 3D scanning, please try some objects which are easy to be scanned. Scanning objects that are too large or too small could be challenging and may require more practice, patience, and technique.
• Face: Designed to scan the human face. The exposure and gain are set according to typical skin reflectivity. The algorithm is customized for human faces.
• Body: Designed to scan the human body.

Suitable for scanning:

Face, Body, Sculpture, Cultural relic, Plaster figure, Plaster model, Relief, Sofa, Chair, Vase, Cultural relic, Motorbike, Doll, Wood carving.

Not suitable for scanning:

Transparent cup (Transparent objects), Mobile phone, High reflective objects, Animal (Dynamic objects), Solid color ball, Featureless objects, Glasses, Tiny structure objects.

Accuracy: Fast and Hi-Quality

• Fast: Faster scanning with relatively good accuracy, offering faster scan and processing speed to get remarkable models. Fast is the default for body scanning.
• Hi-Quality: Added to meet users' needs for higher-precision data capturing. In Hi-Quality mode, the processing time for point cloud optimization, mesh, and texture operations will be relatively longer.

Feature: Geometry and Texture

• Geometry: This scanning mode is ideal for capturing objects with intricate geometric details and irregular shapes. However, it may not be well-suited for objects with many planes or circles. This mode is particularly recommended for scanning materials such as plaster portraits and handmade items.
• Texture: This scanning mode is best suited for objects with rich texture features and intricate color patterns. However, it may not be effective when scanning objects with solid colors or repetitive textures. It is highly recommended to use this mode when scanning objects such as tables with wood texture.

Color Mapping: Color and No Color

• Color: The object to be scanned has both color and shape information in the scanned 3D model (Please export color objects in .PLY or .OBJ file formats with color information).
• No Color: The scanned model has no color information; only the shape information is captured.

Scanning troubleshooting/Tips

How to obtain a high-quality model?

1. Use USB 3.0 or above port.
2. Hi-Quality mode should be chosen.
3. Fewer objects should be in the view of the scanner except your target.
4. Move your hand or rotate the turntable slowly during scanning.
5. Keep the perfect distance according to the prompt during scanning.
6. Adjust the exposure yourself to avoid red or blue parts appearing in the IR image.
7. Keep scanning until all desired parts are adequately scanned (the quality map turns green in quality mode).
8. Set a smaller resolution when optimizing the point cloud.

Preview

The preview phase provides RGB/depth images, IR images, and real-time point clouds for preview, alignment, and quality judgment. The RGB/depth and IR preview windows offer nine squares for alignment. It's recommended to keep the scanning portion in the center area.

The IR preview window allows adjusting the IR exposure method (auto/manual, default auto). IR image exposure affects point cloud integrity and quality. Red portions indicate overexposure (adjust exposure down); blue portions indicate underexposure (adjust exposure up). The RGB/depth preview window can be used to view depth changes. Generally, more complete depth on the scanned target leads to better point cloud quality.

The RGB/depth preview window supports adjusting RGB exposure (auto/manual, default auto). If RGB is overexposed or too dark, adjust the exposure level. This window also displays depth images, which can be superimposed on RGB images by adjusting depth translucency.

Scanning

The main body of the page is a 3D rendering area displaying a point cloud. The point cloud is divided into the current frame and the scanned point cloud. Red in the current frame indicates poor quality; green indicates successful tracking and registration. The scanned point cloud is displayed in quality color mode by default. Orange indicates poor quality requiring rescanning; green indicates good quality meeting model generation requirements.

The 3D rendering area supports interaction during the pause phase:

• Single finger rotation ?
• Two-finger long press and drag (with haptic feedback) ??️
• Two-finger zoom in/out ?

Area Descriptions:

10. FAQs

1. Can the scanner scan small objects?
   It is recommended to scan objects from 15cm-200cm. With extensive experience and high-end equipment (PC or smartphones), you can try scanning smaller objects.
2. Why do I get the message "Ceiling reach!" or "Scanned frames limit reached"?
   The scanning frame limit is dynamically adjusted based on the phone's remaining RAM. If RAM is insufficient, this prompt appears. To scan more frames, close background apps to free RAM and export data to a high-performance PC for model processing.
3. Can the scanner be powered directly by an Android phone without a charging handle?
   If the Android phone supports a USB3.0 Type-C port, it can power the scanner directly. However, this consumes significant power. Using the charging handle is recommended for a stable power supply. Note that scanning consumes more computing resources and phone power.
4. How to avoid tracking loss?
   Return the scanner to the previous correct position and hold for 2 seconds to retrieve the image. If tracking is lost frequently with an electronic turntable:
   (1) Turn on the turntable after clicking "start" and the object is tracked (turns green on screen), then slow down the speed.
   (2) Use a Lazy Susan instead.
5. What system configuration is recommended for scanning?
   
   • Android phones: USB 3.0 or higher interfaces, 8GB or more RAM, Android systems 11-13. Refer to the compatibility list for recommended phone models.
   • PCs: USB 3.0 interfaces, Intel i5 8th generation or higher CPU, 8GB or more RAM, running Windows 10 64-bit or higher (32-bit Windows systems are not supported).
   • Mac: Software (1.0.13) is compatible with Apple M1/M2 series chips and Intel CPUs. Recommended: 8GB or more RAM, Thunderbolt 3/4 or USB 3 interface. For Apple M1/M2 chips, macOS Big Sur 11 or newer is required. For Intel CPUs, macOS 10.5.7 Catalina or later is required.
   • iPhone: iPhone 11 or later (RAM ≥ 4GB, 6GB better) recommended for connection via Wi-Fi 6.
   • Large objects: A device with 16GB or more memory is recommended.
6. Does CR-Scan support USB2.0?
   The scanner supports USB2.0, but the scanning frame rate will be limited by the lower data transmission rate. Scanning accuracy will also be reduced, and some functions may be restricted.
7. How long can the charging handle support continuous scanning?
   It supports over two hours of continuous scanning. Generally, scanning small and medium-sized objects takes within 5 minutes, allowing the charging handle to support 20 to 30 objects.
8. How to restore the connection when the smartphone scanner is disconnected?
   Plug the USB cable on the handle of the rechargeable battery again.
9. Some Android phones show disconnection after a period of time. How to restore the connection?
   If the device is disconnected for more than a certain time (e.g., 10 minutes), some Android systems automatically turn off the OTG connection, leaving the device status offline. Reconnect only after turning on the OTG switch in the Android system.
10. What are the influences of scanning effect?
    
    • The model itself is too thin, too narrow with holes, or has reflective and transparent parts.
    • Other objects are present during preview; remove obstacles and re-scan.
11. What to do if "few point clouds" is shown?
    If the exposure time is too long or too short, cancel automatic exposure and manually adjust the exposure time.
12. USB2.0 is detected while USB3.0 was connected.
    USB3.0 is compatible with USB2.0. If USB3.0 is plugged in slowly, the common pins are detected before the additional USB3.0 pins, causing the connection to be recognized as USB2.0. Plug in USB3.0 quickly to resolve this.
13. How to deal with the warning "Invalid data"?
    If the "Invalid data" warning constantly appears, check scan object settings. Scanning medium objects on a turntable with the "large objects" option selected may trigger this warning. Rescan using the medium (or small) object option, aim at the prominent texture part, or slow down the scanning speed.
14. How to make the scanner work via Wi-Fi if it is disconnected or the display isn't refreshed (≥20s)?
    
    1. Check if the Wireless Bridge indicator light is on and blue. If not, power cycle the Wireless Bridge and reconnect to the hotspot.
    2. Verify the connected WLAN is the Wireless Bridge hotspot. If not, connect to the "Ferret-XXXXXX" SSID.
    3. If the connection is still abnormal, try closing and restarting the APP.
    4. If issues persist, power cycle the Wireless Bridge again and reconnect to the "Ferret-XXXXXX" Wi-Fi.
