3D Scanning Made Simple – ANH is Your Best Solution for Precision & Accuracy
3D scanning is the process of analyzing a real-world object or environment to collect data about its shape, dimensions, and appearance. This data is then used to create a 3D digital model of the scanned object.
This technology captures the geometry of an object using lasers, light, or X-rays. It converts it into a point cloud, which is further processed into a 3D mesh model using specialized software.
How Does 3D Scanning Work?
The basic process involves:
- Scanning — The scanner collects data by measuring the surface of an object from multiple angles.
- Point Cloud Generation — Millions of points are collected to represent the object’s surface.
- 3D Model Creation — The points are converted into a digital 3D model using software.
Depending on the type of scanner used, the method of data capture can vary.
Types of 3D Scanning Technologies
1. Laser 3D Scanning
- Uses laser beams to measure the distance between the scanner and the object.
- High accuracy and detail.
- Common in industrial and engineering applications.
2. Structured Light Scanning
- Projects a pattern of light onto the object and captures its deformation using cameras.
- Ideal for capturing fine details.
- Often used in reverse engineering and art restoration.
3. Photogrammetry
- Uses high-resolution photographs from multiple angles to reconstruct a 3D model.
- More affordable but less precise.
- Used in gaming, VR, and archaeology.
4. Contact Scanning
- Uses a probe that physically touches the object to record data.
- Extremely accurate.
- Used in quality control and metrology.
Applications of 3D Scanning
3D scanning is transforming workflows across many sectors:
Manufacturing & Engineering
