Abstract
An apparatus for stabilizing a camera of an autonomous vehicle includes: a sensor that detects vibration generated and applied to the camera due to a state of a road surface when the autonomous vehicle is traveling; a first actuator that attenuates roll vibration applied to the camera; a second actuator that attenuates pitch vibration applied to the camera; and a controller that controls the first actuator and the second actuator to attenuate the vibration detected by the sensor.
Claims11
An apparatus for stabilizing a camera of an autonomous vehicle, the apparatus comprising:
- a sensor configured to detect vibration generated and applied to the camera when the autonomous vehicle is traveling;
- a first actuator configured to attenuate roll vibration applied to the camera;
- a second actuator configured to attenuate pitch vibration applied to the camera;
- a third actuator configured to vertically move the camera;
- and
- a controller configured to:
- control the first actuator and the second actuator to attenuate the vibration detected by the sensor,
- control the third actuator to move the camera from a holder to a reference location, when the autonomous vehicle is turned on, and
- control the third actuator to return the camera to an original location, when abnormality occurs in the first actuator or the second actuator.
