Video Tracker board 80mm x 90mm

The Vision4ce CHARM-80 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. The CHARM80 has SD resolution analog video interfaces.

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. Within 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).
