Abstract: The present disclosure provides a handheld gimbal control method and a handheld gimbal. The method includes: acquiring an input signal (S301); and performing a first control operation triggered by a first trigger signal in response to the input signal being a predetermined first trigger signal, where the first control operation is used to control the yaw axis motor disposed on the handheld gimbal to start and continue to work so as to enable the imaging device carried by the handheld gimbal to start and continue a rolling rotation (S302). The control method relieves a user from pressing the control button on the handle at all times, thereby improving the flexibility of user operation and user experience.

Abstract: A control method includes obtaining distribution information of a point cloud obtained by a detection device. The detection device includes a light source, and a first reflection assembly and a second reflection assembly configured to cause a light beam emitted by the light source to scan in a first direction and a second direction, respectively, to obtain the point cloud in a detection range. The method further includes, in response to a point cloud line distribution of the point cloud deviating from the second direction, controlling the first reflection assembly to adjust from a current attitude to a target attitude, to correct the point cloud line distribution to the second direction.

Abstract: A video encoding method includes encoding an image to generate a bitstream. In the bitstream, a first syntax element is configured to indicate whether a first chrominance component is filtered by adaptive loop filtering (ALF), and a second syntax element is configured to indicate whether a second chrominance component is filtered by the ALF. The ALF is not a cross-component ALF (CC-ALF) filter.

Abstract: A method for controlling a movable platform includes: displaying a first image and/or a second image on a display device of a head-mounted device, where the first image is captured by a first photographing device on the head-mounted device and the second image is captured by a second photographing device on the movable platform; when switching from displaying the second image to displaying the first image on the display device, sending a safety operation instruction to the movable platform to make the movable platform perform a corresponding safety operation. This disclosure ensures the safety of the movable platform during interactions between the head-mounted device and the movable platform, particularly when the content displayed by the head-mounted device changes. The disclosure also provides a terminal device and a head-mounted device.
