Abstract

The invention discloses a video monitoring cloud platform controlling method and a device and belongs to the field of video monitoring. The video monitoring cloud platform controlling method and the device can obtain cloud platform parameters and lens parameters through a mobile terminal and displays video monitoring images collected by a lens in the mobile terminal. Required rotation angles of the mobile platform and target focal length of the lens are calculated on the mobile terminal based on settings of a user and then a control order is sent to control rotation of a cloud platform or contraction of the lens. With the video monitoring cloud platform controlling method and the device, a monitoring client terminal can visually control the cloud platform so that the lens can accurately be moved to a designated position once or contracted to a required size.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a video monitoring pan-tilt control method and device. Background technique [0002] In the monitoring system, the pan / tilt is used to control the movement of the lens in all directions up, down, left, and right, as well as the zoom of the lens. Usually, on the client side, control commands are sent through keyboards, joysticks and other devices. [0003] Such a control method, the user experience is not very good. First of all, click the control button once, or shake the joystick once, the distance the camera moves, or the size of the zoom is a fixed value. It often takes multiple keys, or shaking the joystick to move the camera to the appropriate position, or zoom to the desired size, especially on handheld devices, when there is no keyboard, only an area on the screen can be drawn to display these controls Buttons, which occupy the image display area, are also very clumsy; se...
