What is a Structured Light 3D Scanner? A structured light 3D scanner is a 3D scanning technology that projects a series of light patterns on the subject and senses the deviations in the pattern to build a digital 3D model of the subject. It is preferred in several fields such as industrial design, engineering, and medical imaging as this scanning process is very accurate and can capture fine details. This technology projects structured light — grids or stripes — onto the object’s surface. A camera then takes pictures of these light patters, and the algorithms rely on these images to tell the 3D shape of the object with millimeter accuracy. 5000μmVery highresolution1 3D scanner(A)10,000μmTypical Structured-lightgenerating5,000μm accuracyis vital for Accurate aerospace and automotive measurements.
Structured light 3D scanners operate at speeds that can take millions of points of data in seconds, allowing them to efficiently scan larger objects or more complicated geometries. From that data, this technology can create detailed 3D models in minutes, a process that would take hours using traditional methods such as manual measuring or photogrammetry. This was quickly followed by structured light scanners, which have become essential tools in rapid prototyping, reverse engineering, and quality control due to their efficiency and speed.
Structured light 3D laser scanners have been prominent in industries such as health, where digital modeling of body parts assist with prosthetics and orthotics. An example would include the use of structured light scanners for custom prosthetic creation, which have increased fitting accuracy by 40%, reducing discomfort associated with a prosthetic and improving function for the end user. Organisations including Revopoint have even introduced structured light 3D scanners that provide both high accuracy and usability, so these devices become viable still for pros and amateurs alike.
Its non-contact nature also makes it well-suited for scanning delicate or fragile objects without damage. In fact, one of the reasons that structured light scanners are used in cultural heritage restoration is their ability to capture surface textures, colors, and geometries in great detail with no physical contact.
If you would like to know about the future features of a 3d scanner, this is a really strong tool and it is transforming more and more industries that need precise, high level 3D models.
