Problems solved by technology
It can be seen that there is a certain delay between the real-time image of the dome camera and the real image, so when locating a certain position, it often takes multiple operations to complete. Among these operations, the user must wait for the previous operation to complete , the next operation can be done according to the position of the current real-time screen, which leads to too much time required to realize the positioning of a position, the user experience is not good, and the operation efficiency is not high; and during this operation, if a certain direction The upper operation range is too large, and reverse fine-tuning is required, and the operation efficiency is low

The invention discloses a zooming method, device, equipment and storage medium of a video image; in this solution, when a user wants to zoom in or out of a video image, he only needs to trigger an operation instruction in the real-time video image, and the operation can be performed according to the operation instruction. The rectangular frame corresponding to the instruction generates adjustment parameters in the frame selection zoom-in mode: up and down pan parameters, left and right tilt parameters and the first focal length parameter, and generates adjustment parameters in the frame selection zoom-out mode: the second focal length parameter, and according to the generated adjustment parameters The camera is controlled to perform corresponding adjustment operations in order to display the adjusted real-time video images. In this way, the user is not required to perform multiple adjustment operations, which improves operation efficiency and user experience.
Description
technical field [0001] The present invention relates to the technical field of video processing, and more specifically, to a zooming method, device, equipment and storage medium of a video image. Background technique [0002] At present, dome cameras generally support PTZ control (Pan / Tilt / Zoom, pan / tilt omnidirectional movement and lens zoom, zoom control) based on Onvif (Open Network Video Interface Forum, Open Network Video Interface Forum), so users can Use the Onvif test tool to connect the dome camera, and use the Onvif command to control the picture of the dome camera to move up, down, left, and right, and to zoom in and out. For example: the user locates the upper right corner of the video screen, at this time the user needs to perform the following operations: a to turn to the right, b to turn up, and c to zoom in. It can be seen that there is a certain delay between the real-time image of the dome camera and the real image, so when locating a certain position, it ...
