Ball machine control method, device and equipment

Abstract

A ball machine control method is applied to processing equipment, and comprises the following steps: after a target object to be tracked is determined, periodically sending a control instruction to a ball machine, and controlling a stepping motor in a cradle head in the ball machine through the control instruction to drive a camera mounted on the cradle head to rotate to a monitoring area where the target object is located, so as to track the target object, so that the processing device tracks the target object based on the image received from the dome camera. Herein, by presetting the period of sending the control instruction, the processing equipment periodically sends the control instruction to the rotatable and variable-magnification dome camera, so that the problem that the response of a holder is always obviously lagged behind the change of the position of a target object in an actual picture when the camera of the dome camera is controlled to rotate at present, and the rotation of the dome camera is not smooth and stable enough is effectively solved. Therefore, the rotation of the dome camera is not blocked any more, smooth and stable tracking of the target object is realized, and thus the use experience of the dome camera is improved.

Description

technical field [0001] The present application relates to the technical field of control, in particular to a dome machine control method, device and equipment. Background technique [0002] The dome camera is a commonly used device in the field of intelligent security video surveillance, including a camera and a pan / tilt used to support the camera. The stepping motor in the pan / tilt drives the camera installed on the pan / tilt to rotate to realize the change of the shooting picture. Because the camera in the dome camera can be rotated and the magnification can be changed, it is widely used in target tracking scenarios in security monitoring. [0003] At present, when the dome camera is tracking the target object, it usually first determines the square box where the target object is located based on the collected image, and then calculates the angle deviation of the dome machine according to the pixel deviation between the center point of the square box and the center point of...

Problems solved by technology

In this way, considering that the response of the pan / tilt often lags behind the change of the position of the target object in the actual picture, the rotation of the speed dome and the change of the magnification will cause the camera to shake, resulting in blurred or lagging of the captured image. Instruction cycle, the processing equipment periodically sends control instructions to the dome camera with rotatable and variable magnification, which effectively overcomes the current shortcomings of not being smooth and stable when controlling the camera rotation of the dome machine, so that the rotation process of the dome machine is no longer stuck To achieve smooth and stable tracking of the target object, thereby improving the use experience of the speed dome
