Video Tracker board 233.3 x 160mm (Double Eurocard)

The Vision4ce CHARM-6U VME video tracker uses the CHARM module and the DART (Detection & Acquisition, with Robust Tracking) detection and target tracking software hosted on an embedded multicore ARM processor board for video tracking and image processing applications.

If appropriate options are selected this board is a replacement for ADEPT 60 and ADEPT 36.

Video Detection & Tracking

A video tracker analyzes video image sequences from a sensor system (one or more cameras), mounted on a servo controlled pedestal (platform) to keep the camera pointing at the nominated person or object. In this context, a Tracker has two primary processing functions.
• Detecting and locating objects of interest in the video image (object location).
• Controlling the platform (Pan and Tilt) position and rate such that the camera follows the designated object (Pan and Tilt Control).
