There are different types of 3D scanning technologies. There are scanners that are suited for short-range while others are suitable for a long distance. The design of the scanner which is used for tinny small is different than those used to scan big equipment like cars. The 3D scanners mostly use the laser while others use light.
Laser scanners use a process called trigonometric triangulation. These sensors function by sending a laser beam to the object and then sensing the reflection. To know how the image looks like, the device calculates the reflections angel. Most of the handheld sensors use laser technology. This kind of scanners is preferred because they can scan almost all types of surfaces.
There are also some scanners that use structured light to scan the target. The most commonly used type of light is white and blue light. The sensor sends the signals in patter and several sensors scrutinize the pattern to determine how the image looks like. This kind of sensors can either be used in handheld and tripod mounted 3D scanners. The main benefit of these types of scanners is that they are quick, have a wide scanning area, accurate, and portable.
Optical scanners, on the other hand, use a camera to track the shape of the image. The system works by attaching light on the object so you can scan it. These kinds of scanners are very accurate. The camera the scanner can be easily moved. You can easily scan every part of the targeted object. The benefit of this system is that you have a higher scanning volume, portable, and have can easily scan the moving object. You can learn more tips for getting a great scanner or read more about 3d scanners.
There are many places where these scanners are used. The scanners are used for industrial design and engineering. They are used to quickly and accurately capture data. Without these 3D scanning, measurement of the could be very challenging in the industry. When 3D scanning is used, there is a quick workflow. They are also helpful in avoiding mistakes and improving productivity.
3D scanners are used in the medical industry. These devices are used to research, care, and creating personalized solutions in the medical industry. 3D scanning is very helpful in implementing various medical technologies. This is helpful in ensuring that there is an improvement in medical procedures. Other places where scanning is used is in forensic, archaeology, art and design, and for educational purposes.
