  • Page 10: Camera Hardware Interface

    SECTION 2 Camera Hardware Interface Installation Overview Before you integrate your camera into your system you should first determine some basic operating parameters such as what resolution you need. Do you know the speed of the object that your camera will be inspecting? One additional point you want to keep in mind is your lighting requirement.

  • Page 30: Lens Modeling

    4.9 Lens Modeling Several camera companies have included this and like information in their manuals. For reference material it is very useful. The focal point is the point at which the image of an infinitely distant object is brought to focus. The effective focal length (f’) is the distance from the second principal point to the second focal point.

  • Page 35: Reference A

    REFERENCE A Camera Link Introduction Camera Link is a Protocol that is Implemented in Channel Link Hardware Camera Link is a communication interface for machine vision. The interface extends the underlying technology of Channel Link to provide a specification more useful in this application. For years, the scientific and industrial digital video market has lacked a standard method of communication.

  • Page 36: Camera Control Signals

    Video Data Signals The Channel Link technology is integral to the transmission of video data. Image data and image enable signals are transmitted on the Channel Link bus. Four enable signals are: FVAL-Frame Valid (FVAL) is defined HIGH for valid lines LVAL-Line Valid (LVAL) is defined HIGH for valid pixels DVAL-Data Valid (DVAL) is defined HIGH when data is valid Spare- A spare has been defined for future use...
