3D sensors are devices that capture information about the three-dimensional shape of an object. They are used in a variety of applications, including industrial inspection, medical imaging, and security.
There are several different technologies used to create 3D images, including laser triangulation, time-of-flight, and structured light. Each of these technologies has its own advantages and disadvantages.
Laser triangulation is the most common type of 3D sensor. It works by projecting a laser onto an object and measuring the angle at which the laser is reflected. This information is then used to calculate the distance to the object and create a 3D image.
Time-of-flight sensors work by measuring the time it takes for a light pulse to travel from the sensor to the object and back again. This information is used to calculate the distance to the object and create a 3D image.
Structured light sensors work by projecting a pattern of light onto an object. The sensor then measures the distortions in the pattern that are caused by the object. This information is used to create a 3D image.
