Abstract

The invention discloses a pan-tilt motor limiting method and device, a pan-tilt camera and a storage medium. The method comprises the following steps: acquiring a sound signal acquired by a microphone; extracting feature information of the sound signal to obtain first feature information; comparing the first feature information with pre-stored second feature information, wherein the second featureinformation is feature information of impact sound generated when the motor and / or the holder impacts the limiting structural member; and if the first feature information is consistent with the second feature information, stopping sending a first rotation instruction to the motor, the first rotation instruction being used for controlling the motor to rotate. In this way, impact noise can be reduced.

Description

technical field [0001] The present application relates to the technical field of pan-tilt cameras, in particular to a method and device for limiting the position of pan-tilt motors, pan-tilt cameras and storage media. Background technique [0002] A PTZ camera refers to a camera with a PTZ, and the PTZ can drive the camera to move. In order to protect the internal structure and components of the camera, the movement of the pan / tilt needs to be limited within a specified range, that is, the movement of the pan / tilt and / or the motor driving the pan / tilt needs to be limited. [0003] At present, there are many kinds of limit methods, such as sensor (optocoupler, Hall sensor, etc.) limit, pure structural limit, etc. However, there are still defects in the existing position-limiting methods. For example, sensors such as optocouplers and Hall sensors are required for sensor limit. The cost of limit is high, and corresponding positions need to be reserved on the structure to plac...
