Calibration Mode is used to calibrate the optical group on a specific rolling stand, and offers the possibility to save calibration parameters in CPU memory or reset them to default values. Work Mode is used to calibrate each rolling stand through screen selection based on the model of the rolling stand under calibration. The operator has the ability to zoom in or out, change/select reference grids, rotate the image, and save any image to CPU memory and/or to an external USB drive in order to record historical calibration data. The E-Vision System facilitates the creation of a database as well as real-time data sharing; this streamlines the roll calibration process through the utilisation of stored information. A video of the E-Vision System can be found on the Continuus Properzi website (under “Press & Media” – Video section) or on YouTube by searching “E-Vision, a new era in rolls calibration”.

The case contains the high-resolution video camera assembly and the backlight (LED) assembly, which are each housed in a protective aluminium cylinder ( Figure 4 ). The VR-CP5 model is shown in the photo. Additional items include the various interconnection cables (for the camera, backlight, power supply and CPU), the flanges required to connect the camera and backlight assemblies to the rolling stands, and an instruction manual. The second case, designated as VR-CPU ( Figure 5 ), is common to all versions of the E-Vision System. It houses the main processing unit (an industrial CPU) which powers the camera and backlight systems, and acquires, processes and sends images via Wi-Fi or via a wired LAN connection. This case also contains the 12" tablet that acts as the operator interface (HMI) and displays the high-resolution images from the camera. Setting up the E-Vision System ( Figure 6 ) is carried out by the following simple steps: 1. Mount the camera and backlight assemblies on the rolling stand 2. Connect the camera and backlight to the CPU panel board via the appropriate cables 3. Connect the CPU to the power supply and switch on the unit 4. Connect the tablet PC to the CPU via Wi-Fi Once the system is connected and the tablet PC has been positioned to the operator’s preference, the calibration operation can begin. Figure 7 illustrates the tablet (HMI) screen. The left side of Figure 7 depicts Calibration Mode while the right side depicts Work Mode.
