CHARM-80SDI
Video Tracker board 80mm x 90mm

The Vision4ce CHARM-80SDI 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 CHARM-80SDI has HD resolution HD-SDI video interfaces.

CHARM-80SDI
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).
