Problems solved by technology

[0004] It is possible to follow and shoot moving objects by using the pan-tilt follow-up method, but it usually rotates and shoots in a fixed direction and a fixed speed, which lacks flexibility and cannot flexibly adjust the rotation speed of the lens according to the actual situation, or adjust the camera device The way of shooting often lags behind the movement of the target object, resulting in poor coherence of the captured picture

Abstract

The invention discloses a following shot control method and device of a cradle head and the cradle head; the cradle head is used for installing a photographic device; the method comprises the following steps of receiving a video image acquired by the photographic device and determining a following shot target of the video image; acquiring first motion information of the following shot target according to the position information of the following shot target in each frame of the video image; acquiring current position information of the following shot target; calculating predicated position information of the following shot target according to the current position information and the first motion information; and acquiring second motion information of the cradle head and adjusting the posture of the photographic device according to the predicted position information and the second motion information. According to the method, in the following shot process, the positions of the followingshot target can be kept consistent in the video image, so that the shot pictures are stable and coherent during the following shot process.

Description

technical field [0001] The present invention relates to the field of cloud platform technology, in particular to a camera tracking control method and device for the platform and the platform. Background technique [0002] The gimbal is a kind of carrying equipment for installing and fixing the camera device. Through the adjustment of the gimbal, the orientation of its lens can be adjusted, so as to accurately realize the observation and shooting of the follow-up target. [0003] Large-scale pan-tilts are mainly used in the modern film and television industry. In order to achieve stable shooting images, such large-scale pan-tilts are often large in size and heavy in weight, which cannot meet the needs of shooting in various environments. At present, hand-held gimbals suitable for daily use have appeared on the market. By installing a camera or mobile phone on the handheld gimbal, holding the gimbal and aiming at the target to shoot, in order to obtain stable and smooth image ...
