Embodiment Construction

[0039] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0040] This embodiment provides a method for switching the working mode of a PIR camera. When the PIR camera detects a change in illumination, or detects that the monitoring target is within a certain range, it needs to switch the working mode. Predict the exposure parameters for switching to another mode, so as to achieve the purpose of rapid exposure adjustment.

[0041] Such as figure 1 As shown, a kind of PIR camera working mode switching method of the present embodiment comprises:

[0042] Step S1, read the current working mode of the PIR camera, and record the exposure parameters of the current working mode.

[0043] The working modes of the PIR camera include black and white mode and color mode. Generally, when the ambient ...

Abstract

The invention discloses a PIR camera working mode switching method and device. The method first reads the current working mode of the PIR camera and records the exposure parameters of the current working mode; Go to the next step, otherwise continue to work in the current working mode; finally set the exposure target value in the switched working mode, combine the exposure parameters of the current working mode to calculate the exposure parameters of the switched working mode, and complete the switching. The device of the invention includes a recording module, a detection module and a switching module. The method and device of the present invention directly predict the exposure parameters of the switched working mode according to the exposure parameters of the current working mode, and do not need to step by step adjust the exposure parameters through photometry and exposure calculation, which greatly improves the switching speed.

Description

technical field [0001] The invention belongs to the technical field of video surveillance equipment, and in particular relates to a PIR camera working mode switching method and device. Background technique [0002] Video surveillance is an important part of the security system. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, the popularization trend of video surveillance has become more and more obvious. [0003] Passive infrared technology PIR (Passive Infrared) is widely used in monitoring front-end equipment, and the monitoring front-end equipment using PIR technology is called a PIR camera. In the application of PIR camera, it will switch to black and white mode and automatically turn on the infrared light in low light environment. When the motion detection mechanism of the PIR c...
