Abstract

The invention provides a method and apparatus for locating panorama camera sub-picture display area and a video monitoring system. The method comprises the following steps: determining a first rotational speed of a sub-picture pan / tilt in the horizontal direction and a second rotational speed in the vertical direction; determining the boundary position of the sub-picture line frame in the horizontal direction according to the first rotation time, the first rotation direction, and the first rotation speed in the horizontal direction of the center of the panorama picture corresponding to the sub-picture pan / tilt; and determining the position of the sub-picture line frame in a panoramic picture according to the boundary position in the horizontal direction and the boundary position in the vertical direction of the sub-picture line frame. The embodiment of the present invention can realize the display of the sub-picture line frame and improve the versatility of the schemes without requiring the front-end device to support the output of the line frame information.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for locating a sub-picture display area of ​​a panoramic camera. Background technique [0002] When the panoramic camera includes a panoramic video channel, it can also be configured with logical display channels of multiple independent sub-picture videos, and the position of each sub-picture in the panoramic image can be selected by the user. Usually, the area currently displayed by each sub-picture is marked in the panoramic picture through a wireframe. It is convenient for the user to locate the position of the sub-picture in the panoramic picture. [0003] In the existing solution, in order to realize the positioning of the sub-picture display area of ​​the panoramic camera, the front-end camera usually outputs the wireframe metadata, and the front-end camera transmits the line of the display area of ​​each sub-picture channel by carrying a priva...
