Camera holder control method, device and equipment and storage medium

Abstract

The invention provides a camera holder control method and device, equipment and a storage medium, relates to the technical field of security and protection, and aims to improve the monitoring effect of a camera. The method comprises the following steps: when a first monitoring target enters a monitoring area of a camera, determining an initial motion strategy adopted by a camera holder for monitoring the monitoring target based on the equipment structure information of the camera holder; controlling the camera holder to rotate based on the initial motion strategy; in the execution process according to the initial motion strategy, determining the motion stage of the camera holder during out-of-step according to the actual rotation angle of the camera holder at each moment and the estimated rotation angle of the camera holder at the corresponding moment determined based on the initial motion strategy; adjusting the initial motion strategy based on the motion stage of the camera holder during out-of-step, and obtaining an adjusted motion strategy; and when the monitoring target of the same type as the first monitoring target is monitored, controlling the camera holder to rotate based on the adjusted motion strategy.

Description

Technical field [0001] This application relates to the field of security technology, providing a camera turbine control method, device, device, and storage medium. Background technique [0002] At present, with the development of artificial intelligence, AI technology, and the user's improvement of camera monitoring requirements, the camera needs to apply to different business scenarios, for example, in the absence of a long distance, The lens of the magnification is fixed-back-round monitoring, or tracks the target of moving at different speeds, or uses a camera to cruise, patrol, and other business scenes. [0003] However, different business scenarios have different requirements for monitoring, accurate, fast and other requirements, and traditional camera turns typically drive the stepping motor, by subdivision, can move the motor moving motor movement At the angle, and according to the strategy presenting a single trapezoidal speed curve or the S-shaped acceleration curve, th...

Problems solved by technology

[0003] However, different business scenarios have different requirements for monitoring stability, accuracy, and speed. Traditional camera pan / tilts are generally driven by stepping motors. Through subdivision processing, the motors of camera pan / tilts can be moved by corresponding steps. distance angle, and according to the strategy presented as a single trapezoidal velocity curve or S-shaped acceleration curve to control the motion state of the camera pan / tilt, however, these strategies will make the camera pan / tilt prone to vibrations and relatively slow acceleration / deceleration during motion. slow situation

[0004] Therefore, the existing strategies often cannot guarantee the monitoring effect in different business scenarios

Moreover, due to the difference in the structure and working environment of the camera pan / tilt, selecting the acceleration / deceleration control strategy only according to the business may cause the motor of the camera pan / tilt to lose synchronization, and when this strategy is continued to be used, it may always occur The situation of out of step, which leads to the accumulation of errors
