Common Vision Blox - Tools



CVB Movie - Software for sequence recording and image archiving

CVB Movie 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.
