Shadow scanning is a technology that utilizes shadow imaging to construct a 3D model of an object, typically a stone or similarly shaped item, by analyzing the contours of its shadow.
In essence, the process involves projecting light onto the object and capturing the resulting shadow. Specialized software then analyzes the shape and dimensions of the shadow, translating this 2D information into a 3D representation. This allows for the creation of a digital model of the object without requiring direct contact or complex scanning equipment that interacts directly with the object's surface.
Here's a breakdown of the process:
- Light Projection: A controlled light source is used to cast a shadow of the object.
- Image Capture: A camera or sensor captures an image of the shadow.
- Shadow Analysis: Specialized software analyzes the captured image, identifying the edges and contours of the shadow.
- 3D Model Creation: Based on the shadow's dimensions and shape, the software generates a 3D model of the original object.
While shadow scanning offers a non-contact method for 3D modeling, it's important to note the existence of more advanced technologies like reflect scan, which uses reflection imaging to achieve even greater precision in 3D model reconstruction. Reflect scan offers improvements in accuracy and detail compared to traditional shadow scanning methods.
