Abstract

The invention provides a camera, which includes a motor, a controller, a memory and a magnetic sensor assembly. The motor, the magnetic sensor assembly and the memory are all connected in communication with the controller; several executable programs are stored in the memory; the controller obtains the target rotation of the motor angle and call the executable program in the memory to drive the motor to rotate; the magnetic sensor component detects the actual rotation angle of the motor; the controller calls the executable program in the memory to compare the actual rotation angle and the target rotation angle, and calls the memory according to the comparison result. The executable program feedback adjusts the rotation angle of the motor. The invention detects the actual rotation angle of the motor through the magnetic sensor assembly and feeds it back to the controller for comparison. The controller drives the motor to rotate according to the comparison result to compensate or reset the lens, which is beneficial to improve the movement accuracy of the lens and improve the shooting quality.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to a camera. Background technique [0002] The camera generally includes a motor and a deceleration transmission mechanism. The motor drives the lens to move horizontally and vertically through the deceleration transmission mechanism, thereby realizing multi-angle shooting of the lens. In order to detect whether the lens rotates to the preset angle, the stepper motor is generally used in the existing camera. By obtaining the step number of the stepper motor, the rotation angle of the stepper motor is calculated by the preset algorithm, and the step is used to calculate the rotation angle of the stepper motor. The rotation angle of the input motor can directly represent the actual angle of the lens rotation. [0003] Specifically, the existing camera is provided with an angle detection device, which includes a sensor for detecting the rotation distance of the stepping mo...
