Embodiment 1

[0065] Such as figure 1 ,

[0066] figure 1 The structural block diagram of the embodiment of the preset position method of the present invention is given, specifically including preset position setting and preset position calling. The preset position setting is mainly to determine the current line number according to the current direction information and magnification of the dome camera , and store the direction information and line number, and the preset position call is to find the line number according to the current direction information of the dome machine, and determine the current focal length according to the magnification sent by the dome machine to the camera, so as to perform accurate and fast preset position transfer.

[0067] Such as figure 2 ,

[0068] A preset position method, comprising the steps of: a preset position setting step and a preset position calling step,

[0069] Such as figure 2 In the process of area A, the preset position setting step in...

Embodiment 2

[0101] Such as Figure 4 , according to the control system generated by the preset position method,

[0102] Including the dome machine control device that can send commands to the dome machine,

[0103] Includes a command parsing module that can parse command headers,

[0104] Including the Focus calculation module that can calculate the Focus value,

[0105] Including the preset position setting line number calculation module that can calculate the line number,

[0106] Including a preset information storage module that can store horizontal angle, vertical angle, and line number,

Abstract

The invention discloses a preset bit method and a control system. The preset bit method comprises the steps of preset bit setting and preset bit calling. According to the step of preset bit setting, current wire numbers are determined mainly according to the current direction information and magnification times of a dome camera, and the direction information and the wire numbers are stored. According to the step of preset bit calling, the wire numbers are searched for according to the current direct information of the dome camera, the current focal length is determined according to the magnification times sent to a camera by the dome camera, and therefore preset bit calling can be carried out fast and accurately.

Description

technical field [0001] The invention relates to the field of camera and video surveillance, in particular to a preset method and a control system. Background technique [0002] In the field of security monitoring, it is necessary to link the key areas to be monitored with the operating conditions of the dome camera. It is necessary to set and store multiple specific monitoring area positions in the back-end controller. When these areas need to be monitored, the controller will Call a preset position set above by sending a command. And this kind of preset position setting and calling method usually needs to store the ball machine direction information, Zoom (magnification) and Focus (gathering) at the same time when the preset position is set, and it can only be called under these specific Zooms. Quickly and accurately call the preset position, so when the preset position is set, the amount of stored data is large, but the information is less. When the preset position is cal...
