  1. BASICS OF 3D SCANNING: HOW STRUCTURED LIGHT SCANNING WORKS

  2. INTRODUCTION • 3D Laser Scanning is a non-contact, non-destructive technology that digitally captures the shape of physical objects using a line of laser light. 3D laser scanners create “point clouds” of data from the surface of an object. • 3D laser scanning is a way to capture a physical object’s exact size and shape into the computer world as a digital 3-dimensional representation.

  3. TYPES There are 3 main types of scanning •  Infrared/time of flight, •  Structured light, and •   Photogrammetry 

  4. Infrared scanning • Infrared scanning identifies the transfer of infrared heat radiation from an object. It provides the means to scan the thermal emissions of various surfaces and display an image of temperature distribution. • This reveals possible problem areas that may need to be dealt with to improve the safety and efficiency of machinery, building structures or electrical apparatus. 

  5. Photogrammetry • The process of photogrammetry revolves around gathering information about an object from photos of it. The photos are taken from different locations and angles to allow for precise calculations that help analysts gather the data. • They use things like photo interpretation and geometric relationships to gather measurements. With the data gathered from photogrammetry.

  6. Structured light Scanning • Structured light scanning is a 3D scanning technology that uses a single light source that projects multiple lines on the object, all of which are tracked by a camera or multiple cameras. • This is in contrast to a laser scanner, which emits multiple laser dots on the object one after the other and it is based on the concept of triangulation. 

  7. Structured light scanning working process • Projecting a single beam of light with uniform intensity will not be enough to make a 3D scan of an object • This is because a single beam of light – or even a uniform gradient black to white – will fail to capture the depth of individual features as it does not reflect the drop off of light intensity because of distance. 

  8. To solve this gap, structured light scanning projects a finely calibrated pattern made of alternating stripes of light gradients on objects. • The very gradual drop off from one stripe to the next allows the cameras to differentiate between the different depth values of the features in an object. AAMS provide 3D Scanning services in Coimbatore.

  9. Conclusion • Aravind Accurate provide the best design solution for all types of Engineering industries by Reverse Engineering Services in Coimbatore and advanced Technological Tool. • Their services include CMM Inspection Service in Coimbatore, Digital Inspection Services in Coimbatore, Rapid proto typing services in Coimbatore and more.
