What is the white light scanner?
White light scanner is a combination of camera and scanner that creates three -dimensional (3D) scanning of the object, especially using white light. This scan can be used for many things, for example for computer drawings (CAD) and reverse engineering. The white light scanner must take many images to assemble the 3D model correctly, and the scanner can be manual or automatic. A marginal pattern or a black and white formula is used to ensure accuracy, add contrast and measure the object during scanning. Before taking pictures, dots and points are manually added to the object, so the computer can properly compile an object in 3D space. In addition to the realistic scanning of the depth, curve and the size of the object, the scanning of white light also provides further use. Information collected from the scan can be added a program CAD, which allows designers to make theoretical changes of the object. Parts can also be reverse engineering so that users can understand what causes objects or parts to work.
To create a 3D model correctly, the white light scanner must take many pictures at different angles of the object. This ensures that the scanner understands the object exactly, so it can be correctly assembled on a computer. Some scanners are automatic and shoot themselves, but most of them are manual and users have to move the scanner around.
When taking the image of the white light scanner, it projects a marginal pattern on the object surface. One camera is responsible for the screening of this pattern, while the other controls the environment and calibration. The use of a marginal pattern facilitates the scanner to understand the size of the physical object and ensures accurate display. By using a marginal pattern, the object has an optimal contact that helps the scanner to pick up the pictures.
Before using the white light scanner, users must prepare an object to be scanned. This includes the addition of small dots and larger point stickers to the object. OneThis is because it further ensures the accuracy of the display. Another reason is that when the scanner takes pictures, it really raises these dots and points. Position information from dots and points is compiled, creating a realistic 3D representation.
