Automated and easy 3D scanning with OpenScan Mini - Guide and test

How to Automate 3D Scanning with OpenScan Mini

Step 1: Understanding Photogrammetry and OpenScan Mini

• 3D scanning with photogrammetry involves taking images of an object from various angles and processing them to create a 3D model.
• OpenScan Mini automates the imaging and 3D file processing for 3D scanning.
• Visit the OpenScan website to learn about OpenScan Classic and OpenScan Mini.
• OpenScan Mini has a maximum scan volume of 8 cm cubed and runs on a Raspberry Pi with a compatible Pi camera.

Step 2: Acquiring and Assembling OpenScan Mini

• Purchase the necessary hardware from the OpenScan shop based on your preferences.
• Download the SD card pre-prepared image for the Raspberry Pi.
• Use Raspberry Pi Imager to write the image to the SD card.
• Assemble the OpenScan Mini by 3D printing the required parts and following the detailed instructions provided.

Step 3: Firmware Setup and Initial Usage

• Connect to the OpenScan Mini by entering the IP address in your browser.
• Update the firmware if necessary to access additional settings.
• Familiarize yourself with the scan interface and configure your OpenScan Cloud token for cloud processing.

Step 4: Preparing Objects for Scanning

• Use 3D scanning spray to reduce reflections on the object's surface.
• Ensure the object has enough texture for accurate tracking during scanning.
• Control lighting to minimize contrast between reflections and shadows on the object.

Step 5: Performing Scans with OpenScan Mini

• Position the object correctly on the turntable and adjust the camera settings for optimal exposure.
• Start the scanning process and let OpenScan Mini automatically capture images from various angles.
• Upload the scan data to the OpenScan Cloud for automated processing.

Step 6: Post-Processing and Analysis

• Download the processed 3D model from the OpenScan Cloud.
• Use software like Meshmixer for cleaning up the 3D scan and making any necessary adjustments.
• Analyze the quality and accuracy of the scanned models for further refinement if needed.

Step 7: Comparing Results and Future Considerations

• Compare the results obtained from OpenScan Mini with other 3D scanning methods like Meshroom.
• Evaluate the speed, quality, and ease of use of OpenScan Mini for your scanning needs.
• Stay updated on new advancements like the OpenScan Mini V2 for potential improvements in 3D scanning capabilities.

By following these steps, you can effectively utilize the OpenScan Mini for automated and easy 3D scanning, producing accurate and detailed 3D models of various objects.
