Anti-interference camera and anti-interference method thereof

Abstract

The invention discloses an anti-interference camera and an anti-interference method thereof. According to the anti-interference method, a coordinate zero point position is positioned in a set range at two sides of an angular bisector of a maximal rotational angle of a cradle head, the position, corresponding to the coordinate zero point position, on a rotary structure is a zero point mark position, a signal device is arranged on the rotary structure according to the zero point mark position, and the coordinate zero point position is detected according to the signal device. The anti-interference camera comprises the rotary structure and a detection module and a setting module for setting the coordinate zero point position, the position, corresponding to the coordinate zero point position, on the rotary structure is the zero point mark position, and the signal device is arranged on the rotary structure according to the zero point mark position; the detection module is used for detecting the coordinate zero point position according to the signal device. The anti-interference camera and the anti-interference method thereof can realize fast powering zero point self inspection, and effectively prevents environment interference.

Description

Technical field [0001] The invention belongs to the technical field of camera pan-tilt zero point positioning, and in particular relates to an anti-interference camera and an anti-interference method. Background technique [0002] In recent years, with the rapid development of computers, networks, and image processing and transmission technologies, the popularization of video surveillance has become more and more obvious. The most commonly used cameras in video surveillance are various cameras as front-end equipment. There are a huge number of them all over the city. The cameras include fixed-position cameras and pan-tilt cameras. The pan-tilt cameras can drive the camera to rotate through the rotation of the pan-tilt for cruise monitoring. [0003] All cylindrical pan-tilt integrated cameras currently on the market require zero point detection when powered on, and use the zero point coordinates to control the pan-tilt rotation angle and monitoring position coordinates. The conve...
