Types of 3D Object Document Cameras

A 3D object document camera is used to capture high-resolution images of an object from multiple perspectives to create a digital 3D model. Various types of 3D object document cameras are available.

• Handheld scanners: A handheld 3D camera scanner is portable and extremely versatile. It can scan virtually any object regardless of size or shape. However, getting pictures of large items can be tedious and time-consuming. In addition, it requires skilled personnel to operate the handheld scanner.
• Stationary scanners: Stationary 3D object document cameras work best for scanning large objects or multiple small items. They are mounted on a stable platform, usually with a turntable underneath. The item to be scanned is turned in a 360-degree motion, while the scanner remains motionless. This setup allows for greater accuracy and finer detail capture. However, the schematic assembly can be a problem if the object is too large to fit onto the turntable.
• Mobile scanners: A mobile 3D object scanner camera comes with a separate stand that can be moved around the object to capture the scans. This option works great for medium to large objects that won't fit on a turntable. Like the handheld scanner, it also requires skilled personnel for proper operation.
• Automatic scanners: The automatic scanner integrates the turntable system for stationary scanning. It also has a built-in camera or laser scanner that can be manipulated via a mobile app or PC. The object to be scanned is placed on the turntable, which rotates automatically for the camera or laser scanner. Although it lacks the detail and resolution of the stationary or handheld scanners, the 3D scan process is very simple and user-friendly. One drawback is that it is not suitable for very large objects.
