In this 3d measuring method, a laser beam is directed via a line lens onto the surface of the object to be measured. With the help of a C3 or C4 camera, a picture of the laser line is acquired from the triangulation angle alpha. As a result of the arrangement of the laser and the camera, any change in the surface make-up below the laser line will lead to the laser line in the camera image being displaced in a defined manner.The task of a C3/C4 camera is to use maximum speed and precision to determine the position of the laser line. Below, you will see a number of typical laser-scanning arrangements. For the approximation of the height resolution data that has been given, the following symbols have been used: dX= resolution along the laser line, dY= resolution perpendicular to the laser line (in the direction in which the object or the camera moves), dZ= resolution in the direction of height.

3D cameras of Automation Technology are designed for a lot of different applications. The cameras accomplish 3d measurements based on the principle of triangulation and export 3D data for the determination of position, height, width and volume. Thus enables you check lots of production criteria in a fully automatic way. AT’s 3D cameras stand out due to its detailed accuracy of measurement, especially for applications with high speed.
