4. user during installation Since vProcess s main feature is to execute vision projects consisting mainly of vision and data algorithms scripts the software packages always include one or several algorithms libraries in form of DLLs and algorithms description files The installer will place the libraries in the adequate folder Besides other folders will be created to include libraries and resources used by the program The folders placed in the installation path are Folder Contains alg Algorithms libraries and description files bin The program executable and runtime libraries cfg Configuration files vision projects model images and model data lib Runtime libraries resources Icons used by the program 3 Program window areas vProcess opens one main window and some secondary windows for performing punctual operations or for showing log messages a log window a camera parameters window and an algorithms parameters window The log window can be made visible and invisible by the user It is not shown by default The camera parameters window appears when the user opens it to modify the parameters of the selected camera Three cameras can be connected The algorithms parameters window appears when the user opens it to modify the parameters of the selected algorithm of the vision project assigned to the selected camera The main window is always visible and is divided into several areas for displaying different information
5. ating system as Windows Embedded Standard 7 We intend to provide full compatibility of vProcess for future Operating System releases as Windows 10 vProcess is distributed by Keysens or its representatives included in software packages that may also include keysens algorithms libraries demo images and demo projects of vision applications vProcess is also distributed ready installed in embedded devices intended to execute machine vision applications The purpose of this manual is to explain the usage of the program s features and the meaning of the information it shows For more technical information on setting up ma chine vision applications please see vProcess technical notes that can be downloaded from www keysens com Particularly vProcess telegrams vProcess configuration files and vPro cess project files Manual 2002 Rev 02 2015 Keysens Machine Vision 2 vProcess User s Manual 2 Installation If you acquired a Keysens Vision Processor such as a vComputer this is an embedded device and vProcess is already installed on it You do not have to install the program If you have a software package containing vProcess then it is distributed as an executable installer program exe When executed the installer will write some folders and files to your computer in the installation path one of these files will be the vProcess executable The installer can also place a desktop link to vProcess and a menu entry if selected by the
