Abstract

The invention provides a handheld automatic follow shot device and a target tracking method thereof. The method uses a handheld holder to obtain a video, and then uses a target tracking algorithm to update the real-time position of a target in each frame of the video, so that by calculating the displacement of the target between any two adjacent frames, the holder is controlled to move, and thereby the method ensures that a user can shoot high-precision stable frames anytime and anywhere. A tracking system ensures that the holder automatically follows the movement of the target to move, and the user does not need to make adjustment all the time.

Description

technical field [0001] The invention relates to the technical field of video imaging, in particular to a hand-held automatic camera follow-up device and a target tracking method thereof. Background technique [0002] In recent years, with the rapid development of electronic technology, photography technology and other fields, an important device for photography - the use of the cloud platform is becoming more and more extensive. The pan / tilt refers to the steering shaft connected to the bottom of the optical equipment and the fixed bracket, and is a supporting workbench for installing the imaging device. The imaging device refers to an imaging device such as a video camera or a still camera. The imaging device is placed on the pan-tilt, and by adjusting the pan-tilt, the lens orientation can be adjusted, so as to accurately observe and photograph the target. Large-scale pan-tilts are mainly used in the modern film and television industry. In order to achieve stable shootin...
