Problems solved by technology

However, these anti-shake technologies have too high requirements on hardware, and are mainly applicable to the hand-shake problem during the shooting process of mobile phones and cameras, and are not suitable for application scenarios where the pan-tilt camera is operated by a motor

Abstract

The invention discloses a speed control device for a holder camera. The device comprises an instruction reception unit used for receiving a rotation instruction for driving the holder camera to rotate, a displacement calculation unit used for calculating a displacement distance of the holder camera from the present position to a target position according to the rotation instruction, a speed querying unit used for querying a pre-stored speed and an acceleration model according to the displacement distance to acquire a motor rotation speed, and a driving control unit used for sending the motor rotation speed acquired through querying to a motor control end of the holder camera to drive the holder camera to rotate to the target position. Through the device, jittering of the holder camera can be eliminated to a great degree at relatively low cost.

Description

technical field [0001] The present invention relates to camera transmission technology, and more particularly, to a speed control method and device for a pan-tilt camera. Background technique [0002] The pan-tilt camera is provided with a rotating motor. When the motor drives the camera to rotate, it needs the camera to rotate to a predetermined position within a predetermined time, so the camera needs to rotate to a predetermined position at the highest speed. In the prior art, the motor directly drives the camera to rotate at a rated maximum speed, so the picture captured by the camera will shake, thereby affecting the shooting quality. [0003] The existing anti-shake technology mainly includes natural anti-shake technology, such as: increasing the sensitivity to increase the shutter speed; optical anti-shake technology, such as: using a special lens or the structure of a charge coupled device (CCD), which can Use these anti-shake technologies to reduce the impact cause...
