Calibrating a 3D scanner is a crucial process that ensures the accuracy and reliability of the scanned data. Especially with the CR-Scan Raptor, a high-precision 3D scanner from Creality, proper calibration is indispensable to guarantee consistent results and high-quality data. In this comprehensive guide, we will discuss in detail when calibration is necessary, how it is performed, and which factors should be considered during the process.

When should the CR-Scan Raptor be calibrated?

To ensure the CR-Scan Raptor delivers optimal results, it should be calibrated in the following situations:

1. Initial Setup

When the scanner is set up for the first time, calibration is essential to ensure it is properly adjusted to the environmental conditions and requirements.

2. Regular maintenance

If the scanner is unused for a long period (e.g., over a month), precision may change. Recalibration restores the original accuracy.

3. Environmental changes

Temperature fluctuations, changes in humidity, or lighting can affect the scanner's performance. A significant temperature change (e.g., more than 10°C) requires calibration.

4. Moving or vibration

If the scanner is moved or accidentally dropped, this can lead to measurement deviations. Strong vibrations during transport can also negatively affect precision.

5. Noticeable errors

If the model's accuracy significantly decreases or the point cloud is incomplete or no depth map is created, this is a clear sign that calibration is necessary.

6. After software updates

After every firmware or software update, calibration should be performed to ensure the new software parameters are correctly applied and performance is not affected.

How to calibrate the CR-Scan Raptor?

Calibrating the CR-Scan Raptor requires careful procedure to ensure the scanner operates at the highest level. Here is the step-by-step guide:

1. Check calibration board

Make sure the calibration board is type CBR1, as the Raptor only works with this specific board. Each calibration board is unique and cannot be used with other scanners.

2. Connect scanner to computer

Remove the protective film from the scanner's camera. Then connect the CR-Scan Raptor to your computer and open the "Device: CR-Scan Raptor" interface.

3. Start calibration

Click "Calibrate" and follow the animated instructions on the screen. Start by scanning the QR code on the back of the calibration board.

4. Align calibration board

Rotate the calibration board so that the marked side faces up. Tilt the scanner 15° to the left relative to the board's central axis, then slowly move it vertically from bottom to top. Repeat this process by tilting the scanner to the right, forward, and backward.

5. Check calibration points

Be patient during the calibration process. The higher the score, the better the accuracy. A score above 90 is aimed for to ensure precise results.

Important considerations when calibrating the CR-Scan Raptor

CR-Scan Raptor: The comprehensive guide to optimal 3D scan performance

Introduction

The CR-Scan Raptor is a highly precise 3D scanner specifically designed for applications requiring metrological accuracy. With a maximum accuracy of 0.02 mm and the use of a 7-line blue laser along with a 2.3-megapixel camera, the CR-Scan Raptor delivers extremely detailed and sharp 3D data. Whether small objects like coins or large items like statues and vehicle parts, the CR-Scan Raptor masters all challenges. This guide provides a detailed overview of the key features, best practices, and advanced tips to take your scans to the next level.

Technological fundamentals and operation of the CR-Scan Raptor

Precision scanning with blue and infrared light

The CR-Scan Raptor uses both blue light and infrared light technology to scan a wide range of objects under various conditions. While the blue light mode is specifically optimized for highest precision on small and detailed objects, the infrared mode is better suited for larger objects such as human bodies or artworks.

Blue light scanning

• Applications: Small parts (e.g., coins, bolts) or objects with complex geometries.
• Features: High accuracy up to 0.02 mm, requires markers to support the scan.
• Procedure: For small objects, markers can be placed on the scan table; for larger objects, markers should be attached directly to the object's surface.

Infrared scanning

• Applications: Larger objects such as statues or human bodies (150-2000 mm).
• Features: Marker-free scanning possible, but also supports scanning with markers and texture features.
• Advantage: Ideal for objects that are more difficult to scan with blue light, such as very dark or metallic surfaces.



Project management and scan configuration

Before starting a scan, you can set the project name and the save path at the top. We recommend using the object's name as the project name to facilitate recognition and management of multiple projects.

At the bottom, select the appropriate configuration based on the object to be scanned and the environment. The software offers video tutorials and presets to help you choose the optimal settings.

Scanning and point cloud preview

After starting the scan, you will reach the main scan interface. Here, you can monitor the preview of the image and point cloud display:

• Depth camera preview (IR mode): This displays the infrared image from the depth camera. We recommend manually adjusting the IR exposure to achieve optimal point cloud quality. Overexposure (blue/red) should be avoided.

• RGB camera preview: In this window, you can see the color image from the RGB camera. Here, you can also manually adjust the exposure to obtain high-quality images.

Recommendations for the scanning process

To achieve an optimal scan result, you should pay attention to the following aspects:

• IR-Exposure: Adjust the exposure so that the marking points and laser lines are clearly visible in the preview window.
• Distance display: The software offers a distance display that helps you maintain the ideal distance between scanner and object. Follow the recommendations to avoid distortions or data loss.

High-resolution camera and LED lighting

The CR-Scan Raptor's integrated 2.3-megapixel camera provides exceptionally detailed and sharp images, while 12 white LED lights ensure clear textures can be captured even in low-light environments. This combination enables excellent results even under challenging lighting conditions.

Optimizing scanning settings for best results

Adjusting the resolution

Choosing the right resolution plays a crucial role in the quality of the 3D model and the duration of the scanning process. A distinction is made between the resolution in real-time scanning and the resolution in point cloud optimization.

• Real-time scanning resolution: This setting affects the appearance of the model during the scanning process. A finer resolution provides more detailed real-time models but requires more memory. For smaller objects, e.g., about 10 cm in size, a resolution of 0.15 mm is recommended.
• Resolution in point cloud optimization: This setting determines the level of detail of the final 3D model. For most objects, a point spacing resolution of 0.1 mm is sufficient. For very detailed models or small objects, a resolution of 0.02 mm can also be used, but at the cost of significantly increased processing time.

Sensitivity and filtering of the point cloud

• Sensitivity: A higher value means more points are retained, while a lower value filters out more points. The correct setting depends on the complexity and level of detail of the object.
• Filtering: Filtering unnecessary points can reduce processing time and improve model quality.

Point cloud optimization and editing

Optimizing the point cloud after the scanning process is crucial to create a high-quality 3D model. This includes merging multiple scan passes into a consistent dataset and removing unwanted points.

Tips for avoiding artifacts and improving scan quality

Avoiding line artifacts

Line artifacts often occur in very detailed scans when the resolution is set too high. To avoid these artifacts, we recommend the following measures:

1. Use an adequate resolution: A resolution of 0.1 mm is sufficient in most cases and avoids over-detection of details that lead to artifacts.
2. Proper Exposure and Laser Intensity: Ensure that the laser lines and markers are clearly visible but not overexposed.
3. Overlapping Scans: Cross-scanning the same areas helps minimize errors.
4. Increase the Number of Scan Images: The more images taken of an area, the more detailed and accurate the 3D model will be.

Multi-Project Merging

The CR-Scan Raptor offers a powerful multi-project merging feature. This allows multiple scans of an object to be combined into a complete model. This function is especially advantageous for larger objects. Please observe the following steps:

• Ensure Overlapping Areas: Make sure that each scan captures sufficient overlapping areas to enable seamless merging.
• Manual Merging: For even more accurate results, the merging of point clouds can be manually optimized.

Advanced Features and Fine Tuning

Mesh Generation and Smoothing

After optimizing the point cloud, it can be converted into a mesh model. Here, you can manually adjust the number of faces, the degree of smoothing, and hole closure. The more faces the mesh contains, the finer and more detailed the final model will be.

• Number of Faces: More faces lead to higher detail accuracy but increase processing time.
• Smoothing Settings: Stronger smoothing can eliminate irregularities in the model but may also result in the loss of small details.

Texture Capture and True-Color Models

The CR-Scan Raptor is equipped with a high-resolution RGB camera that captures true colors for the model. This is especially useful when creating models for visual presentation. For texture capture, we recommend:

• Good Lighting: Even when using the built-in LED lighting, ensure the environment is well-lit to avoid shadows and distortions.
• Multiple Shots: Take multiple scans from different angles to minimize color changes and distortions.

CR-Scan Raptor: Troubleshooting Connection Issues

The CR-Scan Raptor from Creality is a powerful 3D scanner designed for high-precision scanning. However, connection issues can occasionally occur during use, disrupting the workflow. In this article, we provide a comprehensive guide to troubleshooting connection problems with the CR-Scan Raptor. By following these steps, users can ensure the scanner operates optimally and delivers excellent results.

Optimization of scanning conditions

Precision of light modes

For improved precision, we recommend preferring the blue light mode over the infrared mode. It offers higher accuracy, especially for detailed scans. However, in both modes, it is important to adjust the exposure time of the IR camera to achieve medium exposure. Overexposure appears in red areas, while underexposure is indicated by blue areas.

Adjust laser power

When scanning in blue light mode, the laser power should also be adjusted. This ensures optimal capture of the object's surface and improves detail accuracy.

Maintain optimal scan distance

The distance of the scanner to the object is crucial for scan quality. Basically: the closer the scanner is to the object without losing tracking, the better the details are captured. Correct positioning and a constant distance lead to a precise scan image.

Point cloud optimization and modeling

Point cloud optimization

For small objects, the point spacing should be reduced during point cloud optimization. A setting of 0.1 mm is ideal here. This fine adjustment ensures detailed capture of the object's surface and improves the overall quality of the model.

Model meshing

During the meshing process, it is important to ensure that the number of model faces is sufficiently large. This prevents inaccuracies and gaps in the finished 3D model and ensures a smooth and precise surface.

Multi-project scanning and merging

Using the multi-project merging function

Creality Scan offers the possibility to merge multiple scans of an object into a complete model. This is especially useful when the object needs to be scanned from multiple angles. A multi-part scanning process begins with capturing a visible area, followed by rotating the object to achieve a complete scan through backtracking.

Handling small objects and marker points

Marker points for small objects

Smaller objects, such as figures or components, require placing marker points on the scanning substrate. These markers allow the scan to be performed in point mode, enabling precise capture of small and complex objects.

Blue light mode

Reflective marker points are required for the blue light mode, which are glued onto the surface of the object. These markers improve tracking and enable detailed capture of the object's geometry.

Infrared mode

In infrared mode, reflective marker points should be used if the scanned object has few geometric features. These markers can be attached to the object's surface to facilitate tracking.

Texture mode

If an object has few geometric features but rich textures, such as a vase, it can be scanned directly in texture mode. This mode captures the surface structure of the object and provides detailed texture information.

Scanner calibration

Calibration interval

It is recommended to calibrate the CR-Scan Raptor if it has not been used for an extended period (e.g., after three months) or after a fall or damage. Calibration ensures that the scanner functions correctly and delivers accurate results.

Calibration plate

Each calibration plate is unique and matched to a specific scanner. When used for the first time, the plate must be paired with the scanner via the printed QR code. This ensures that the calibration is performed accurately.

After each calibration, the plate should be carefully stored in its protective case to avoid scratches or damage.

Proper connection to the computer

USB connection issues

When using a desktop computer, it is advisable to connect the scanner via the USB 3.0 port on the back of the device. USB 3.0 ports are usually marked in blue or red. If the scanner is not recognized, it is recommended to try an alternative USB 3.0 port or use a USB Type A to Type C adapter.

Check system requirements

It is important to ensure that the operating system supports Windows 10/11 64-bit and that the system configuration meets the scanner's minimum requirements. The software should also be installed directly in the system's root directory to avoid compatibility issues.

Device and firmware management

Firmware updates

Updating the scanner's firmware to the latest version is crucial to ensure compatibility with the Creality Scan software and to resolve potential connection issues. Regular updates also improve the overall performance of the scanner.

Camera access permissions

Check the operating system's privacy settings and ensure that camera access is enabled for desktop applications. These permissions can be configured in the Windows settings under Privacy > Camera.
