Compared to 3D laser scanning, structured-light scanners can offer advantages in speed and safety by using non-coherent light sources like LEDs or projectors instead of lasers. This approach allows for relatively quick data capture over large areas and reduces potential safety concerns associated with laser use.
PrimeSense's depth acquisition was enabled by "light coding" technology. The process coded the scene with near-IR light, light that returns distorted depending upon where things are (Structured light). The solution then used a standard off-the-shelf CMOS image sensor to read the coded light back from the scene using various algorithms to ...
The advantage of structured-light 3D scanners is speed and precision. Instead of scanning one point at a time, structured light scanners scan multiple points or the entire field of view at once. Scanning an entire field of view in a fraction of a second reduces or eliminates the problem of distortion from motion.
Structured light is the process of projecting a known pattern (often grids or horizontal bars) on to a scene. The way that these deform when striking surfaces allows vision systems to calculate the depth and surface information of the objects in the scene, as used in structured light 3D scanners .
The active stereo vision is a form of stereo vision which actively employs a light such as a laser or a structured light to simplify the stereo matching problem. The opposed term is passive stereo vision. Conventional structured-light vision (SLV) employs a structured light or laser, and finds projector-camera correspondences. [2] [3]
A white light scanner (WLS) is a device for performing surface height measurements of an object using coherence scanning interferometry with spectrally-broadband, "white light" illumination. Different configurations of scanning interferometer may be used to measure macroscopic objects with surface profiles measuring in the centimeter range, to ...
This comparison of optical character recognition software includes: . OCR engines, that do the actual character identification; Layout analysis software, that divide scanned documents into zones suitable for OCR
Artec's 3D scanners are structured light scanners. [14] They operate by projecting light in a pattern, usually in the form of multiple parallel beams, onto an object. By projecting a grid pattern on the object, the scanners are able to capture the deformation or distortion from multiple angles and then calculate the distance to specific points ...
