Problems solved by technology

[0004] However, this method still has shortcomings: when the user presses the mouse button in the virtual keyboard window, the front camera can only be controlled at the same speed in the same horizontal or vertical direction, and the control efficiency is low.
Secondly, when there are multiple video images in the video display window, the user needs to select a certain video image first, and then click the virtual keyboard to perform PTZ control operations. The steps are cumbersome and the camera cannot be controlled quickly and quickly.
Furthermore, its PTZ operation mode is completely visible, occupying the display screen interface, affecting the magnification ratio of the displayed image, and bringing visual blind spots and inconvenience to the operator

Embodiment 1

[0028] refer to figure 2 , which is Embodiment 1 of a remote control method for a front-end camera provided by the present invention. This embodiment may specifically include the following steps:

[0029] Step 201: Obtain the video image captured by the front-end camera and display it in the video window.

[0030] In the specific implementation process, the real-time monitoring video code stream can be obtained from the network first, and the obtained real-time monitoring video code stream is decoded by using Microsoft Directshow technology, and then the decoded video frame is rendered into the video window.

[0031] One or more video images can be displayed in the video window at the same time. In the case of displaying multiple video images, each video image may be arranged in a matrix in the video window. The user can enlarge or reduce the display ratio of each video image according to needs, that is, multiple video images in the video window can occupy interfaces of dif...

Embodiment 2

[0040] refer to image 3 , which is Embodiment 2 of another remote control method for a front-end camera provided by the present invention, this embodiment may specifically include the following steps:

[0041] Step 301: Obtain the video image captured by the front-end camera and display it in the video window.

[0042] In the specific implementation process, the real-time monitoring video code stream can be obtained from the network first, and the obtained real-time monitoring video code stream is decoded by using Microsoft Directshow technology, and then the decoded video frame is rendered into the video window.

[0043] One or more video images can be displayed in the video window at the same time. In the case of multiple video images, each video image can be displayed in the video window in any form, such as a matrix or a circle. The user can enlarge or reduce the display ratio of each video image according to needs, that is, multiple video images in the video window can...

Abstract

The invention discloses a remote control method and system for a front-end camera. The method includes the following steps: acquiring a video image taken by a front-end camera and displaying it in a video window; judging whether the current cursor display position is located in a certain video image, and if so, setting the control mark group and the set for controlling the front-end camera Superimpose and display the above-mentioned certain video image; perform remote control on the front-end camera according to the operation of the user on the control mark group. The system includes an acquisition and display video unit, a judgment cursor position unit, a superimposed display unit and a remote control unit. Through the method and system provided by the invention, the user can control the front camera to move in any direction at any speed, which is significantly improved compared with the traditional control method.

Description

technical field [0001] The present invention relates to the field of security technology, more specifically, to a method and system for remote control of a front-end camera PTZ. Background technique [0002] With the development of economy and society, and the continuous improvement of people's demand for security protection, video surveillance systems have been rapidly developed and popularized in the past few decades. development in the direction of networking. In the traditional video monitoring system, because the analog technology is mainly used, the system scale is generally small, and the users are few and generally concentrated in the monitoring room. In this case, it is generally only necessary to configure several control keyboards and joysticks in the monitoring room to realize the remote control (PTZ, Pan / Tilt / Zoom) of the front-end camera, that is, to realize the control of the pan / tilt and the camera. [0003] In the new generation of video surveillance syste...
