When performing 3D scanning of people and animals, special attention needs to be paid to the following aspects to ensure the accuracy of the scanning data and the detailed reproduction of the model:
1. Posture and Stance
-
Characters: Ensure that characters are posed in a natural way, avoiding movements that obscure the face or details, such as crossed arms or sitting postures, which can make it difficult for the scanner to capture the full body features.
-
Animals: Since animals are often not easy to work with, it is recommended that they be scanned when they are still or in a relaxed state. Try to avoid rapid movements of the animal, which can be achieved by gently calming or rewarding them for a more stable posture.
2. Light conditions
-
Try to scan under a soft, even light source, avoiding glare, shadows or reflected light, and especially avoid backlighting. Overly bright or dim light sources can affect the performance of the scanner, resulting in loss of scanned data or increased noise.
-
Indoors: you can use a soft light to evenly illuminate the object being scanned.
-
Outdoor: Avoid direct sunlight and choose a cloudy day or an environment with controlled indoor light.
3. Scanner parameter settings
-
Adjust the scanner resolution and scanning distance according to the size and detail requirements of the object. For faces or small animals that require high detail, select high resolution and a closer scanning distance.
-
Pay attention to the scanning speed, if you move too fast, it may lead to faults or ghosting during the scanning process.
4. Material and Color
-
3D scanners may be affected by reflective materials, so it is recommended to avoid wearing clothing made of highly reflective or transparent materials, especially metal jewelry, brightly colored fabrics, etc.
-
For animals with dark colors or black hair, you can adjust the sensitivity of the scanner appropriately to avoid data loss due to light absorption.
5. Stability
-
People or animals need to be kept as still as possible during the scanning process to ensure data integrity. Especially for full-body scanning, it is recommended that the person being scanned avoid moving his/her head or limbs.
-
Use tools such as brackets and stationary tables to ensure the stability of the scanning equipment and the object being scanned.
6. Multi-angle scanning
-
To ensure data integrity, especially the face, hair and hand details of a person or the ears and tail of an animal, scanning can be done from multiple angles. Scanning from multiple angles reduces shaded areas and blind spots and helps to generate more accurate 3D models.
7. Data Processing
-
Real-time data checking: check the data quality in real time during the scanning process, find problems and rescan in time to avoid the need for large-scale repair later.
-
Software processing: After scanning, use software to process the data, remove noise and repair missing parts to optimize the integrity of the model.
8. Scanning Environment
-
Simple background: Avoid complex backgrounds or surfaces with textures to minimize interference with the scanner and ensure that only the needed objects are acquired.
-
Sufficient space: especially for large animals or multi-person scans, ensure sufficient scanning space so that the device can cover all angles of the object.
Having these details in place can significantly improve the quality of the scan and make the final 3D printed model of the person or animal more vivid and realistic.
