Invention:
This invention presents a method for performing full-field 360-degree 3D measurements of complex objects and human bodies using advanced projection technology originally developed for virtual reality applications. Captured light reflected from the object’s surface as well as the surface shape are reconstructed using advanced 3D imaging technologies such as structured light, deflectometry, and photometric stereo to get the measurement. This invention has the potential to perform accurate 360-degree 3D measurements of complex objects with mixed reflectance properties, such as statues, large astronomical mirrors, car bodies, human bodies, and other metrology applications.
Background:
Currently, there is an issue of insufficient coverage of surface area in optical 3D imaging. Traditional 3D scanning methods often struggle with achieving full-surface coverage, particularly for objects with complex geometries or reflective surfaces. Current techniques require multiple scans from different angles, leading to occlusions, stitching errors, and incomplete data. This technology has the potential to solve this issue by allowing for high-resolution and accurate 3D scanning without the need for repositioning objects or multiple scanning passes. With this new use, this system can be adapted to use as a scanning device and help produce sufficient and accurate coverage of complex objects for 3D imaging in several industrial fields.
Applications:
- Optical 3D imaging
- 3D measurement
- 3D scanning
- 3D metrology
- 360-degree measurement
Advantages:
- More sufficient coverage of surface area
- More accurate coverage of surface area
- Higher efficiency as a result of not needing multiple scanning passes or object repositioning
- Novel application in several industrial fields
