The embodiment of the invention discloses a rotary camera-based video-tracking method, comprising the steps as follows: starting a rotary video recording mode of a terminal camera; obtaining a target recording object which is set by the user, and determining moving data of the target recording object according to a moving state of the target recording object; determining a rotary direction of the camera according to the moving direction of the target recording object, and determining rotational speed and rotational acceleration of the camera according to the moving speed and acceleration of the target recording object; triggering the camera to perform rotary video recording according to an original state and the rotational speed of the camera, and rotating the camera in the rotary direction according to the rotational acceleration to keep the relative positions of the camera and the target recording object unchanged. The embodiment of the invention further discloses a terminal. The rotary camera-based video-tracking method and the terminal of the embodiment of the invention could strengthen operational stability of the tracking videos of target persons, thereby improving recording quality of the video and user experience of the terminal video recording.
Description
technical field [0001] The present invention relates to the field of electronic technology, in particular to a method and terminal for tracking video recording based on a rotating camera. Background technique [0002] At present, with the increasing popularity of mobile phones and the increasingly powerful recording function of mobile phone cameras, more and more mobile phone users like to take pictures or record videos with their mobile phones. In the prior art, when a mobile phone user uses the video recording function of the mobile phone to track and record people in application scenarios such as outdoor activities or character performances, a handheld device is required for tracking and recording. If the video recording time is long, the user of the handheld device will experience arm shaking or unstable holding height due to overweight phenomena such as arm soreness; or during video recording, because the movement of the handheld device and the movement of the recording...
