Problems solved by technology

At present, the 3D control function of the control pan / tilt simply divides the current camera field of view according to the image segmentation method stipulated in the agreement, so as to obtain the angle that the pan / tilt needs to rotate. When the pan / tilt has an elevation or depression angle, it will lead to 3D positioning The accuracy is not high and the error of the gimbal will increase with the increase of the elevation angle (depression angle)

Embodiment Construction

[0026] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] A method to improve the positioning accuracy of the cloud platform, such as figure 1 As shown, firstly, by establishing the 3D mathematical model of the gimbal movement, and then calculating the compensation function of the current gimbal horizontal angle and vertical angle of the position that the gimbal needs to move according to the model, and secondly, performing 3D control on the gimbal When , the angle that the pan-tilt needs to move is calculated through the compensation function, and finally, the pan-tilt motor control module drives the pan-tilt motor to run to the corresponding position to achieve. The present invention specifically comprises the following steps:

[0028] Step 1: Establish a 3D mathematical model of the gimbal movement.

[0029] This step takes the pan-tilt as the center of the sphere, and the image that can b...

Abstract

The invention relates to a method for increasing the location accuracy of a cloud platform. The invention has the main technical characteristics by comprising the following steps of (1) establishing a 3D (Three Dimensional) mathematical model for the movement of the cloud platform; (2) calculating a compensation function of the position of the cloud platform needing to move relative to a horizontal angle and a vertical angle of the current cloud platform according to the 3D mathematical model for the movement of the cloud platform, and calculating a compensation angle of the cloud platform needing to move; and (3) enabling a cloud platform motor driving module to drive a cloud platform motor to execute the compensation angle of the cloud platform. According to the method disclosed by the invention, the design is reasonable, the 3D control accuracy of the cloud platform is increased, the 3D location and accurate execution can be accurately realized by the cloud platform under various different elevation angles, the development trend of a video surveillance industry can be adapted, better experience can be brought for a user as well, and the method has the characteristics that the implementation is easy, the control is simple, the applying effect is obvious, and the like.

Description

technical field [0001] The invention belongs to the field of video monitoring, in particular to a method for improving the positioning accuracy of a pan-tilt. Background technique [0002] PTZ is the most commonly used front-end monitoring equipment in video surveillance system. With the continuous development of monitoring technology, the 3D function has become an indispensable function of the cloud platform. At present, the 3D control function of the control pan / tilt simply divides the current camera field of view according to the image segmentation method stipulated in the protocol, so as to obtain the angle that the pan / tilt needs to rotate. When the pan / tilt has an elevation or depression angle, it will lead to 3D positioning The accuracy is not high and the error of the gimbal will increase with the increase of the elevation angle (depression angle). With the development of video surveillance systems, people's requirements for 3D positioning accuracy are also increas...
