Analog Video/PAL Video Tracker
Introduction
AV tracker consists of two circuit boards, with the lowest weight and size in the industry. Excellent real-time image processing technology and broad usage make the tracker very user-friendly to be integrated into the photoelectric pod/gimbal and other mobile or static systems.
Features
· Adapt to image affine transformation caused by high speed movement
· Adapt to target panning, zooming, rotation and partial occlusion
· Adapt to illumination variation
Affine transformation is the shape changes caused by relative displacement of two objects, and we use ARM+FPGA structure-based template-matching algorithm to improve the tracking stability of the tracker so that the device could still follow any shaped moving target even it is panning, spinning or partically blocked as well as in low light condition.
