Abstract

The invention discloses a PTZ rotation control method and device. The method comprises the following steps: obtaining starting positioning information through a magnetometer and/or a gyroscope on a mobile terminal, wherein the starting positioning information comprises at least one of an initial azimuth angle and an initial dip angle; sensing the displacement change and obtaining stopping positioning information through the magnetometer and/or the gyroscope, wherein the stopping positioning information comprises at least one of the current azimuth angle and the current dip angle; and controlling the PTZ to rotate according to the starting positioning information and the stopping positioning information. According to the technical scheme provided by the invention, the operation manner is simple and easy, no screen space is occupied, and the linear rotation can be realized without constantly carrying out fine tuning according to the played pictures fed back by preview.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method and device for controlling the rotation of a pan-tilt. Background technique [0002] At present, existing mobile terminals such as smartphones and tablet computers are integrated with magnetometers and gyroscopes. A magnetometer is an instrument used to measure the direction of a magnetic field, which can be used to locate a device's orientation. The magnetometer can be understood as the compass of the mobile terminal, which can obtain the azimuth angle of the mobile terminal at any tilt attitude (that is, the horizontal angle between the north direction line of a certain point and the target direction line in a clockwise direction), That is, the orientation of the terminal. A gyroscope is a device used to sense and maintain the angle between directions, and is used to judge the tilting posture of the device. The gyroscope can obtain the angle between the mobile termin...
