CVB Movie is a Common Vision Blox tool that can record video
sequences and save them as AVI files directly to hard disk ready for
subsequent playback using either Image Manager or any other suitable
playback software. Using an appropriately configured computer with
an adequate RAID-disk array, impressive data rates are possible.
As CVB Movie uses the DirectShow Video Codecs that are available to
the system at the time of recording, various movie formats can be used.
Depending on the Video Codec selected, even video files compressed
with the most modern compression algorithms can be recorded.
Naturally the Video Codecs used have to be available on both the
recording and playback systems.
In industrial and scientific machine vision there are many application
areas where continuous recording of sequences may be needed. The
video data that the system stores, may be used for documentation and/
or later analysis. Besides the continuous recording of camera data, it is
also possible to record preselected images, for example, only those
images that show defective parts.
As the videos can be played back using CVB Image Manager, they can
also be used for development purposes or for testing machine vision
software, in cases where no online testing is possible.
As the core of our recording solutions, CVB Movie guarantees robust
and secure image storage to RAM or disk and supports a variety of
additional features such as adding a timestamp or user specific
information such as GPS-data directly synchronised to the image data.
This data is not visible on the image, but is clearly allocated to the
individual image as meta data. Combined with our experience in
building customer specific PC vision systems we have the expertise to
work with customers to deliver image recording platforms with
guaranteed underlying performance leaving the appli cation functionality to the developer, removing significant risk. Our consultants are
also available to code specific functionality into a bespoke solution that
meets your needs.
Separation of image recording and image analysis
Recording of memory intensive image sequences directly to hard disk
Recording of portable, compressed video sequences, i.e. for email dispatch for use in feasibility studies
